France eSIM & Mobile Internet Guide (2025): Airport Setup, Speeds, FUP

30 Oct 2025

Planning data for Paris, Provence or the Alps? An eSIM is the easiest way to get online in France the moment you land. This guide explains exactly how to set up at CDG/Orly, what speeds to expect in cities, on the Metro, and on the TGV, and how EU Fair Usage Policy (FUP) actually affects travellers. We’ll also help you choose between a France-only plan and a multi-country eSIM for cross-border trips.

France has four nationwide operators (Orange, SFR, Bouygues Telecom, Free Mobile). In 2025, urban 5G is widely available with solid 4G fallback. Paris is well covered, including most of the Metro and RER corridors; rural pockets still exist in mountains and deep countryside. With a compatible, unlocked phone, you can install your eSIM in minutes and keep your home SIM for calls/OTPs while using local data.

Ready to go? If France is your main stop, start with Esim France. For multi-country trips, see Esim Western Europe. Explore more country guides via Destinations.

The mobile networks in France (and what that means for you)

Orange: Best overall coverage, strong in cities and on motorways; reliable rural reach.
Bouygues Telecom: Competitive urban 5G and good suburban/rural coverage.
SFR: Strong in cities and many regional towns; variable in remote areas.
Free Mobile: Great value and fast in cities; patchier between towns and on some rail lines.

Most travel eSIMs auto-connect to one or more of these networks. You can often manually select a network in your phone’s settings if performance varies.

Real-world speeds (2025)

Paris and major cities (5G): 100–300 Mbps typical; peaks above 500 Mbps are possible in uncongested cells.
Paris and major cities (4G/LTE): 20–80 Mbps typical.
Suburban/rural 4G: 10–40 Mbps typical; 5G in larger towns.
Busy venues (stadiums, big events): Speeds can drop at peak times due to congestion.

These are practical ranges; your exact results depend on your device, network load, and location.

Paris Metro and RER coverage

Coverage in stations: Generally strong 4G across the network; 5G present in many central stations.
Tunnels: 4G works on most lines and corridors; brief dropouts can happen between stations, especially on older tunnels and deeper sections.
RER A/B inner zone: Usually solid 4G; gaps possible outside the core.
Contactless payments and app tickets usually validate without issue, but download QR tickets and passes to your wallet in case of brief no-signal sections.

Pro tip: If you need a continuous data session for video calls, avoid scheduling them during Metro rides; the above-ground bus or tram is more consistent.

Choose the right eSIM for your trip

France only: Short stays or France-focused trips? Pick Esim France for best value and local speeds.
Multiple countries: Visiting Spain, Italy or neighbours on the same trip? Use Esim Western Europe. For country-specific legs, compare Esim Spain and Esim Italy.
Coming from or heading to the US/Canada: Combine with Esim United States or a regional Esim North America.
Business travellers: Centralised purchasing, sharable allowances, and staff management are available via For Business.

Airport setup at CDG and Orly: from wheels down to data in 5 minutes

You can install an eSIM anywhere, but airports are noisy and time-pressured. Here’s the no-fuss approach that works at both Paris Charles de Gaulle (CDG) and Orly (ORY).

Before you fly

Check your phone is unlocked and eSIM-compatible.
Buy and add your eSIM profile (scan QR or use activation code) but don’t “turn it on” yet if your plan starts on first connection.
Label the new line “France Data” so it’s easy to recognise.
Download offline maps for Paris/France (Google Maps/Apple Maps) and any ride-hailing apps.
Update your OS/apps over Wi‑Fi at home.

On arrival (CDG/ORY)

Connect to the airport’s free Wi‑Fi so you’re not relying on your home SIM.
Open Mobile/Cellular settings and enable the eSIM line you added earlier.
Set it as “Mobile Data/Cellular Data”. Keep your home SIM for calls/texts if needed.
Turn on Data Roaming on the eSIM line.
Wait up to 2–3 minutes for network registration. You should see 4G/5G bars.
If prompted for APN, accept the default or use the one provided in your eSIM instructions (most set automatically).
Test with a quick webpage and a maps search.

Pro tips: - Avoid surprise roaming: Set your home SIM to “Calls & SMS only” and disable data on the home line. - If speeds are poor right at the gate, walk towards arrivals halls; coverage is usually stronger. - Dual-SIM iPhone: Set “Default voice line” to your home SIM and “Cellular Data” to the eSIM. Leave iMessage/FaceTime tied to your existing number or Apple ID.

Troubleshooting at the airport

No service after 3 minutes:
Toggle Airplane Mode for 10 seconds, then off.
Manually select a network: try Orange, then Bouygues, then SFR.
Restart the phone.
Connected but no data:
Ensure Data Roaming is on (for that eSIM line).
Check APN auto-filled; if blank, re-open the eSIM install email/app to confirm the APN.
5G unstable:
Force 4G/LTE temporarily in Network Mode; re-enable 5G later in the city.
Still stuck: Use airport Wi‑Fi to contact support through your order email/app while you’re in a good signal zone.

Typical speeds and performance by location

CDG and Orly terminals: 4G/5G from multiple operators; 50–200 Mbps typical once you’re out of the jet bridge.
Central Paris (above ground): 5G 100–300 Mbps typical; 4G 20–80 Mbps.
Paris Metro/RER: 4G in stations and most tunnels; 5–40 Mbps typical with short drops between some stations.
TGV between cities: Expect alternating fast 4G/5G and brief no-service sections at high speed or in cuttings/tunnels.
Countryside/coastal routes: 4G typically 10–30 Mbps; occasional 3G/no-service in remote valleys or national parks.
Ski areas/Alps: Resorts and towns are covered; lifts and high-altitude valleys vary. Cache maps offline.

EU Fair Usage Policy (FUP): what travellers need to know

EU “Roam Like at Home” lets domestic EU plans roam across member states with limits to prevent abuse. For travel eSIMs:

If your plan includes EU roaming, you can use data in other EU/EEA countries, but a fair-use cap may apply separate from your headline allowance.
Providers may also set sensible-use rules (e.g., a maximum continuous roaming period, or throttling after heavy use).
Switzerland is not in the EU; many EU bundles exclude it. Check plan details if you’ll transit via Geneva/Zürich or alpine passes.
Hotspot/tethering is generally allowed, but heavy hotspot use can trigger throttling on some plans.

How to stay within FUP: - Check the “EU usage” and “countries included” notes on your chosen plan. - Download big OS/app updates on Wi‑Fi. - Stream at SD/Auto when on mobile. - For multi-country trips, a regional plan like Esim Western Europe can be simpler than juggling multiple single-country caps.

Hotspot, tethering and dual-SIM tips

Hotspot works on most travel eSIMs. Expect battery drain; carry a power bank for day trips.
Laptops can chew through data. Disable cloud backups/sync and video auto-play when tethered.
Keep your home SIM active for calls/2FA, but set “Cellular Data” and “Allow Mobile Data Switching” carefully, so your phone doesn’t sneak onto home data.
Messaging: WhatsApp, Telegram and iMessage continue to work with your existing number even when mobile data comes from the eSIM.

Data sizing: how much should you buy?

Light user (maps, rides, emails, some socials): 0.5–1 GB/day.
Typical city break (photos, socials, light video): 1–2 GB/day.
Heavy user (hotspot, HD video, frequent video calls): 3–5 GB/day.

Examples: - 3–5 day trip: 5–10 GB. - One week: 10–20 GB. - Two weeks with hotspot: 20–40 GB.

If in doubt, start with a sensible bundle; top up or add another plan mid-trip if needed.

Coverage on the move: driving and rail

Autoroutes (A-roads): Generally strong 4G/5G along major corridors.
National/departmental roads: Good near towns; expect occasional dips between villages.
TGV/Intercités: High speed and terrain can cause short dead zones. Messaging and maps sync just fine; real-time video calls are hit-and-miss.
Hire cars: Many have CarPlay/Android Auto; cache maps and playlists offline for tunnels and mountain passes.

Pro tip: Enable offline map areas for the regions you’ll traverse. Even small offline regions keep navigation seamless during brief dropouts.

Quick pre-trip checklist

Unlocked, eSIM-compatible phone confirmed.
eSIM purchased and profile added; activation planned for arrival.
Home SIM data disabled upon landing; calls/SMS left on if needed.
Offline maps, tickets, translation packs downloaded.
Power bank packed; hotspot settings reviewed.
Plan choice confirmed: Esim France or Esim Western Europe for multi-country trips.

FAQ

Will my phone work with eSIM in France? Most recent iPhones (XR/XS and newer) and premium Androids (Google Pixel, Samsung Galaxy S/Note/Flip/Fold, many mid/high-tier devices) support eSIM. Your device must be unlocked. Check your model’s eSIM support in settings before you buy.
Which network should I use for best coverage? Let the eSIM auto-select first. If you need to choose manually, Orange and Bouygues typically offer excellent national coverage, SFR is strong in cities, and Free Mobile performs well in urban areas. Try another network if speeds are inconsistent in your spot.
Can I use my France eSIM in other EU countries? If your plan includes EU roaming, yes—subject to FUP and included country list. For cross-border trips to Spain/Italy and beyond, a regional plan like Esim Western Europe is often easier. For single-country legs, compare Esim Spain and Esim Italy. Switzerland is usually excluded from EU bundles.
Will hotspot tethering work? Yes on most plans. It uses your allowance faster—especially with laptops—so monitor usage and cap background updates when tethering.
How do I avoid roaming charges from my home SIM? On arrival, set your eSIM as the only line allowed for mobile data and disable “Allow Mobile Data Switching”. Keep your home SIM on for calls/SMS if needed, but with data off.
I’m flying into France and then to the USA. What’s the easiest setup? Use Esim France during your time in France, then switch to Esim United States for the US leg, or pick Esim North America if you’ll also visit Canada. Manage both from your phone and toggle the active data line per country.

Next step: Choose your plan and get connected in minutes with Esim France.

Andes Highlights (3 Weeks): Peru–Bolivia–Chile–Argentina Connectivity

Planning a south america itinerary 3 weeks through the high Andes? This route stitches together Peru’s Sacred Valley, Bolivia’s La Paz and Salar de Uyuni, Chile’s Atacama Desert, and northern Argentina’s quebradas or Mendoza wine country—often by long-distance bus and a couple of short flights. Connectivity is different at altitude: coverage is strong in cities but drops in high passes and salt flats; bus Wi‑Fi is patchy; border towns can be blackspots. The smart move is an eSIM with multi‑country coverage, backed by offline maps, offline translations, and a simple routine for crossing borders by bus without losing service. Below you’ll find a practical, connectivity-first itinerary; checklists to prep your phone, apps and documents; and on-the-ground tips for staying online where it matters: booking transport, hailing taxis, backing up photos, and navigating when the signal disappears.If you’re transiting via Europe or North America, you can also add a layover eSIM to stay connected door-to-door. Start with our country list on Destinations, then follow the steps, and you won’t waste time chasing SIM shops at 3,500 metres.The 3‑week Andes route at a glanceWeek 1: Peru (Cusco, Sacred Valley, Machu Picchu) - Fly into Cusco (or Lima then connect). - Base in Cusco; day trips to Pisac/Chinchero/Maras–Moray. - Train to Aguas Calientes; Machu Picchu visit; return to Cusco or continue to Puno/Lake Titicaca.Week 2: Bolivia and Chile (La Paz, Uyuni, San Pedro de Atacama) - Bus/collectivo via Copacabana to La Paz. - Fly or overnight bus to Uyuni. - 3‑day Uyuni–altiplano tour ending in San Pedro de Atacama (Chile).Week 3: Chile and Argentina (Atacama to Salta or Mendoza/Buenos Aires) - Choose: - North: San Pedro to Salta/Jujuy by bus; fly to Buenos Aires. - Or South: San Pedro–Calama flight to Santiago; bus or flight to Mendoza; onward to Buenos Aires.Connectivity notes (quick): - Cities: generally strong 4G/4G+; 5G in major hubs (Santiago, Buenos Aires). - Altitude/rural: expect long no‑signal stretches (Uyuni, altiplano passes, Paso Jama). - Bus Wi‑Fi: often advertised, rarely reliable. Plan to be offline onboard. - Border regions: networks switch; a multi‑country eSIM avoids sudden loss.eSIM vs local SIMs for a 4‑country tripFor a route with multiple borders and remote legs, eSIM wins on time and reliability.What a multi‑country eSIM gets you: - One plan across Peru, Bolivia, Chile, Argentina (check coverage per country on Destinations). - No passport/SIM registration queues at kiosks. - Keep your home number active on the physical SIM for calls/SMS codes. - Instant top‑ups if you burn data on photos or navigation.When a local SIM still helps: - Long stay in one country with heavy data use (e.g., a month in Buenos Aires). - Dead zones where a different local network performs better (rarely worth the hassle on a 3‑week pace).Practical approach: - Use an eSIM as your primary data line across all four countries. - If you find a specific local network far better in one region, add a cheap local SIM and keep the eSIM as backup.Device readiness checklist (before you fly)1) Check eSIM compatibility and SIM‑lock status on your phone.2) Buy and install your eSIM while on home Wi‑Fi. Keep a PDF/printed copy of the QR code.3) Label lines clearly (e.g., “eSIM Andes Data”, “Home SIM”).4) Turn on data roaming for the eSIM; leave roaming off for your home SIM to avoid charges.5) Set up dual‑SIM rules: data on eSIM; calls/SMS default to home SIM if needed.6) Download offline: Google Maps/Organic Maps for all target regions; language packs (Spanish at minimum); bus/air tickets; hotel confirmations.7) Cloud backups: set to upload on Wi‑Fi only; pre‑create shared albums for travel companions.8) Test tethering/hotspot with your laptop/tablet.If you’re transiting popular hubs, consider a short layover eSIM: - USA connections: add an Esim United States or a broader Esim North America.- Europe connections: Madrid/Barcelona? Use an Esim Spain. Paris or Rome? See Esim France and Esim Italy. Multi‑country layovers? Try Esim Western Europe.City‑by‑city connectivity notesCusco & the Sacred Valley (Peru)Coverage: Good in Cusco city; variable in high villages (Maras/Moray) and along Inca Trail approaches.Tips: Download Sacred Valley maps offline; pin viewpoints and ruins. most taxis use WhatsApp—save your accommodation’s number.Machu Picchu/Aguas Calientes: Patchy to none at the citadel. Upload your photos later; don’t rely on live ticket retrieval.Lake Titicaca: Puno and CopacabanaPuno: Reasonable 4G; bus terminals crowded—screenshot QR tickets.Crossing to Copacabana: Expect a signal drop around the border; have directions saved offline.La Paz (Bolivia)Good urban 4G; the cable car network has decent signal but tunnels do not.Yungas/“Death Road” tours: Mountain valleys cause dead zones—share your emergency contacts with the operator, carry a charged power bank, and don’t plan remote calls.Uyuni and the Altiplano (Bolivia to Chile)Uyuni town: OK 4G; ATMs finicky—use Wi‑Fi for banking apps.Salt flats/lagunas: Assume offline for most of the 3‑day tour. Guides often carry satellite phones; agree a pickup time/place in San Pedro and preload your map route.San Pedro de Atacama (Chile)Town: Solid 4G; accommodations often have Wi‑Fi but speeds vary.Geysers, Valle de la Luna: Offline navigation essential; sunrise trips start before mobile networks wake up in some areas.Salta/Jujuy or Mendoza/Buenos Aires (Argentina)Salta/Jujuy: Good city coverage; quebradas have long no‑signal sections.Mendoza: City 4G/5G; vineyards outside town can be patchy.Buenos Aires: Strong 4G/5G; ideal for cloud backups and large downloads before you fly home.Border crossings by bus: step‑by‑stepThe big ones on this route: Peru–Bolivia (Puno/Copacabana), Bolivia–Chile (Uyuni–San Pedro via Hito Cajón), Chile–Argentina (Paso Jama to Salta or Los Libertadores to Mendoza).How to keep service and sanity:1) The day before:- Top up your eSIM data.- Confirm your plan includes both countries you’re entering/leaving.- Download offline maps for both sides of the border and your town of arrival.- Save bus company WhatsApp and terminal address offline.2) On departure morning:- Keep a paper copy or offline PDF of tickets, insurance, and accommodation proof.- Charge phone and power bank; pack a short cable in your daypack.3) On the bus:- Don’t count on bus Wi‑Fi. Keep your eSIM as primary, but expect drops near mountain passes.- If your phone supports it, enable “Wi‑Fi calling” for later when you reach accommodation Wi‑Fi.4) At the border posts:- Data may be unavailable. Keep QR codes and booking numbers offline.- After exiting one country and entering the next, toggle Airplane Mode off/on to re‑register on the new network.- If the eSIM doesn’t attach, manually select a network in Mobile Settings.5) Arrival:- Send your accommodation a quick WhatsApp when you’re back online.- Recheck your eSIM’s data roaming is on; confirm you’re on an in‑country network, not a weak roaming partner.Pro tips: - Dual profiles: If your eSIM allows, keep a secondary profile for a different network in the same country—helpful in border towns.- Cash buffer: Some border terminals don’t accept cards; download a currency converter for offline use.Offline survival kit (5‑minute setup)Maps: Download regions for Cusco, Sacred Valley, Puno, La Paz, Uyuni, San Pedro, Salta/Jujuy or Mendoza, and Buenos Aires.Translations: Download Spanish for offline use; add phrasebook favourites (bus tickets, directions, dietary needs).Documents: Save PDFs of passports, tickets, hotel addresses; star them for quick access.Rides: Screenshots of pickup points; pin bus terminals and hotel doors.Entertainment: Podcasts and playlists for long bus legs, set to download on Wi‑Fi only.Altitude and your tech: what changesCoverage gaps lengthen: Fewer towers at high altitude; valleys can block signal. Assume offline on remote excursions.Batteries drain faster in cold: Keep your phone warm and carry a power bank (10,000–20,000 mAh).Hotel Wi‑Fi may be congested: Schedule big uploads (photo backups, app updates) for big-city stays like Santiago or Buenos Aires.GPS still works offline: Your blue dot shows on offline maps without data—preload everything.Data budgeting for 3 weeksTypical traveller usage across this route: - Messaging/Maps/Bookings: 0.2–0.5 GB/day- Social and photo sharing: 0.3–0.7 GB/day- Occasional video calls/streaming: 0.5–1.0 GB/dayFor a mixed-use trip, plan 15–25 GB for 3 weeks. Heavy creators should double it and upload over hotel Wi‑Fi when possible. If you work remotely, consider a higher‑capacity plan and a backup eSIM; see our guidance on For Business.Practical route with transport and connectivity cuesDays 1–4 Cusco base: Strong city signal; day trips may be spotty—go offline-ready.Days 5–6 Machu Picchu: Expect no service at the ruins; sync tickets ahead.Days 7–8 Puno to La Paz via Copacabana: Border signal drop; re‑register networks after crossing.Days 9–11 Uyuni tour to San Pedro: Treat as offline; charge nightly; carry spare cables.Days 12–14 San Pedro: Stable in town; tours offline; top up data before Paso Jama.Days 15–17 Salta/Jujuy or Mendoza: Good urban 4G; rural patches are offline.Days 18–21 Buenos Aires: Strongest connectivity of the trip; clear your uploads and map downloads for the flight home.Partnering and stopover extrasHospitality and tour operators in the Andes: help your guests stay connected—explore co‑branded solutions via our Partner Hub.Transatlantic flyers: test your eSIM setup on a layover with an Esim United States or Esim Western Europe before hitting high-altitude blackspots.FAQs1) Do I need a local SIM in each country?No. A multi‑country eSIM covering Peru, Bolivia, Chile and Argentina is simpler and works well for a 3‑week pace. Consider a local SIM only if you’ll spend longer in one country and want the absolute best regional coverage.2) Will my WhatsApp number change with an eSIM?No. WhatsApp is tied to your registered number, not your data line. Keep your home SIM active for voice/SMS (roaming off if you wish), and use the eSIM for data—WhatsApp continues as normal.3) Can I hotspot to my laptop or camera?Yes. Enable tethering on your eSIM. Mind your data: cloud backups and OS updates can burn gigabytes—set them to Wi‑Fi only or schedule in big cities.4) What if there’s no signal on the Uyuni/Atacama legs?That’s expected. GPS still works offline. Pre-download maps and translations, carry a power bank, and sync plans with your tour operator before departure.5) Will I get roaming charges at borders?If you’re using a multi‑country eSIM with coverage in both countries, you won’t incur extra roaming fees from your home carrier. Keep roaming off on your home SIM to avoid accidental use.6) I’m connecting via Europe or the US—worth getting a layover eSIM?Yes. It’s an easy way to test your setup and stay reachable. Try Esim North America or country options like Esim Spain, Esim France, or Esim Italy for common hubs.Next step: Browse South America coverage options and build your plan on Destinations.

Private APN & Enterprise Security: When and Why to Use It

Mobile data isn’t just “internet in your pocket.” For enterprises with roaming staff, payment terminals, or IoT fleets, the path your traffic takes is a security control. A private APN creates a closed data path from SIMs to your network, letting you enforce policy, isolate traffic from the public internet, and integrate cleanly with VPNs or zero-trust tools. This guide explains what private APNs are, when to use them, how they work with VPNs, typical use cases, what they cost, and how to deploy successfully—without jargon.If your teams travel, the stakes go up: roaming adds new networks, new attack surfaces, and variable policies. A well-designed private APN keeps device traffic predictable and governable across borders. Whether you’re connecting laptops via eSIM, securing field equipment across Esim Western Europe, or building a partner-ready solution via our Partner Hub, the right APN choice determines how easily you can meet audit, compliance, and uptime targets.Use this as a practical checklist to decide if a private APN fits—and how to keep costs and complexity under control.What is a Private APN?A private APN (Access Point Name) is a carrier-side configuration that defines how SIM traffic is handled. Rather than breaking out to the public internet using NAT on a generic, shared APN, a private APN:Identifies your SIMs into a dedicated routing contextAssigns private/static IP ranges if requiredApplies custom firewall, DNS and content policiesDelivers traffic to you over a defined path (e.g., IPsec/GRE to your DC/cloud)Think of it as “your own lane” inside the mobile core, with enterprise-grade traffic isolation and policy controls.Key benefitsTraffic isolation: Your devices don’t share a public NAT pool with everyone else.Predictable addressing: Private or static IPs allow IP allowlisting and system-to-system integrations.Policy enforcement: Apply DNS filtering, firewall rules, and segmentation per SIM group.Controlled breakout: Choose where traffic exits—your data centre, cloud VPC, or a regional gateway.Common variantsPrivate APN with public breakout: Policy and IP control, but final internet egress is via carrier NAT.Private APN with private breakout: End-to-end private path to your network over IPsec/GRE/MPLS; no public internet until you decide.Roaming home routing vs local breakout: Decide whether traffic tunnels back to a home gateway or breaks out regionally for latency/compliance.When should you use a Private APN?Choose a private APN when one or more of these apply:You must IP-allowlist mobile devices to access corporate apps, SCADA, or payment backends.You need to block open internet access by default, allowing only approved destinations.You require consistent, auditable logs of device egress and DNS activity.You deploy IoT/OT fleets where devices are headless and should never be internet-reachable.You need static or reserved IPs per SIM for device-to-cloud rules or legacy systems.You’re operating in higher-risk or compliance-heavy sectors (finance, health, critical infrastructure).Travel scenarios where it shines:Regional workforces moving between the US, Canada and Mexico using Esim North AmericaTeams rotating across France, Italy and Spain with Esim France, Esim Italy and Esim SpainShort-term projects needing fast onboarding in the US via Esim United StatesCheck your target countries and carriers via Destinations.Private APN vs VPN vs Zero TrustThese are complementary, not either/or.Private APN: Carrier-layer isolation and policy. Ensures trusted device identity (SIM/IMSI), private addressing, and controlled gateways.VPN (IPsec/GRE/SSL): Secure tunnel from APN gateway to your network or cloud VPC. Use to terminate traffic into your security stack.Zero Trust/SASE: Identity-driven access per user/device/app. Often layered on top (device certificate, posture checks) for user devices.Recommended patternsCorporate laptops/phones on the roadPrivate APN + clientless approach: Route all traffic via your gateway where CASB/SWG runs.Or Private APN + device VPN: Enforce split tunnel for corporate apps; APN blocks all other internet.IoT/OT equipmentPrivate APN with private breakout to your VPC/DC; no public internet access.Partners/contractorsPrivate APN with segmented SIM groups and per-segment firewall policies; issue time-bound SIMs.Pro tips: - Avoid double encryption where unnecessary. If APN-to-cloud IPsec is in place and devices only talk to your internal services, you may not need device-level VPN. - Use device certificates via MDM/EMM for user hardware.

Match your APN design to the route permitted in the destination. Confirm on Destinations.IP allowlists and roaming IPsIf you rely on static source IPs, avoid scenarios where roaming uses dynamic CGNAT or changes egress country by country. Private breakout fixes this by presenting consistent IP space.Device onboarding during traveleSIM QR provisioning helps. Pre-stage profiles for each region (e.g., Esim France for an EU tour, Esim United States for US trips).Cost model: what you’ll actually payExpect costs in these buckets:One-off setupAPN configuration, IP ranges, SIM group policies, initial tunnel(s)Monthly platform feeCovers APN gateway capacity, monitoring, and managementPer-SIM chargeOften tiered; sometimes includes static IP optionsData usagePooled or per-SIM; roaming may have regional ratesTunnels and hostingIPsec/GRE tunnel endpoints in your DC/VPC; cloud egress costs may applyChange management/professional servicesPolicy updates, incident support, new region gatewaysWays to optimise: - Start with a private APN + public breakout for policy control; add private breakout later for critical apps. - Use regional gateways to avoid transatlantic hairpin data charges for travellers. - Reserve static IPs only for systems that truly need allowlists; use dynamic private IPs elsewhere. - Monitor top talkers; block chatty apps at APN firewall instead of paying for unnecessary data.Quick decision checklist: do you need a private APN?Tick “yes” if the statement is true:We must restrict mobile devices from open internet by default.We rely on IP allowlists for any critical app or third-party API.We need device fleet observability (per-SIM traffic and DNS logs).We operate IoT or unattended devices that should never be publicly reachable.We have travellers across multiple regions and require consistent egress policies.We must meet compliance or audit requirements for network segregation.Three or more “yes” answers usually justify a private APN.Implementation: step-by-step1) Define scope and risk - List device types (laptops, phones, IoT), users, and data sensitivity. - Map apps/domains/ports that must be reachable. - Decide “deny-by-default” vs “allow-by-default”.2) Choose coverage and form factor - Confirm countries and networks via Destinations. - Select regional plans (e.g., Esim North America or Esim Western Europe) and country add-ons (Esim Italy, Esim Spain).3) Addressing and segmentation - Allocate private subnets per SIM group (e.g., staff vs IoT). - Decide where static IPs are required.4) Breakout architecture - Start with private APN + public breakout if you only need policy/DNS controls. - For maximum control, deploy private breakout to your DC/cloud via IPsec/GRE. - If latency matters for travellers, request EU and US gateways.5) Security policy and DNS - Set default deny; allow only business apps/domains. - Enforce DNS to your resolvers; block DoH/DoT egress except approved endpoints. - Add geo/ASN blocks for risky destinations if relevant.6) Integrate identity and device posture - Bind SIMs to users via MDM/EMM; consider IMEI binding for corporate-owned devices. - For user devices, layer device certificates or ZTNA for application-level control.7) Build and test tunnels - Establish redundant tunnels; validate failover. - Test roaming from target countries (US/EU) for latency and policy correctness.8) Logging, monitoring, and alerts - Export flow and DNS logs to SIEM. - Create alerts for policy violations and unusual data volumes.9) Pilot and scale - Pilot with 10–50 users/devices across two regions. - Iterate rules, then scale to full fleet.Pro tips: - Test common collaboration apps (Teams/Zoom) for split vs full tunnel to avoid performance complaints. - Document emergency bypass processes for critical field operations.Common pitfalls (and how to avoid them)IP allowlists failing during roamingUse private breakout with consistent source IPs; avoid reliance on roaming CGNAT ranges.DNS leaksForce DNS to your resolver; block outbound UDP/TCP 53/853 except to approved IPs; manage DoH with SNI filtering.Overly broad “allow” rulesPrefer FQDN and minimal port ranges; segment by SIM group.Latency surprisesPlace gateways regionally; verify RTT from your top travel corridors.Tunnel single points of failureAlways build at least two tunnels to independent endpoints.Who is this for?Enterprises securing roaming staff devices with eSIMPayments, logistics, and field services managing unattended endpointsMSPs/ISVs embedding connectivity into their solutions via our Partner HubOrganisations looking for turnkey policies and global eSIM bundles via For BusinessFAQQ1: What is the main difference between a public and a private APN?A private APN creates an isolated routing context for your SIMs with custom policies and addressing. Public APNs use shared NAT to the internet with limited control and no dedicated security posture.Q2: Do I still need a VPN if I use a private APN?Often yes, but it depends. For IoT or tightly controlled fleets, APN-to-cloud IPsec may be sufficient without device VPN. For user devices, a device VPN or ZTNA provides identity and app-level control on top of the APN.Q3: Can I get static IPs for my SIMs?Yes. Private APNs can assign static or reserved private IPs per SIM, which is ideal for IP allowlisting and legacy integrations. Public static IPs are possible but less common; many use private breakout and egress via corporate firewalls.Q4: Will a private APN work while roaming internationally?Yes. Design for either home routing (all traffic returns to your gateway) or regional breakout (e.g., EU/US). This affects latency and compliance—verify coverage per country on Destinations.Q5: How much does a private APN cost?Expect a setup fee, a monthly APN platform charge, per-SIM pricing (optionally for static IPs), data usage, and tunnel/cloud costs. You can start small with policy-only public breakout, then add private breakout and regional gateways as needs grow.Q6: Does this support eSIM and multi-region bundles?Yes. Private APN policies apply to both physical SIMs and eSIMs. For travellers, pair your APN with regional plans like Esim Western Europe or Esim North America and country-specific options such as Esim France or Esim United States.Next stepDesign the right private APN for your fleet and travel patterns.
