Travellers are often surprised to learn that many countries now require “real‑name” registration to activate a local SIM or eSIM. In plain terms: you may need to show ID (usually a passport) and complete a quick form or selfie check before your number works. Other destinations still allow anonymous purchase, especially for data‑only plans. This guide summarises SIM registration by country across 30 of the most-visited destinations, so you know what to expect at the airport kiosk, high‑street shop, or when activating an eSIM in‑app.
We update this list quarterly and link out to the most relevant country and regional guides, including Esim United States, Esim France, Esim Italy, Esim Spain, Esim Western Europe and Esim North America. For everything else, browse all country pages via Destinations.
What is SIM registration?
SIM registration (aka “real‑name registration”) ties a mobile number to an individual using a recognised ID. It usually happens: - At point of sale (airport desk, carrier shop, authorised reseller) - Online or in an app (video KYC, document upload, eID), especially for eSIM
Authorities use it to limit fraud and spam. For travellers, it means carrying your passport and sometimes completing a quick selfie or address check.
Quick prep checklist (save this before you fly)
- Bring your physical passport and one backup photo/scan stored offline.
- Know your accommodation address (hotel is fine) and a reachable email.
- Have a payment method that matches your name (card or digital wallet).
- If you want a local plan on arrival, favour official carrier stores or airport counters for smoother tourist KYC.
- Consider activating an eSIM before departure to skip queues. Regional options like Esim Western Europe and Esim North America cover multi‑country trips.

Notes: - “Need ID?” reflects national rules for prepaid activation; retailers can still choose to verify even in “No” markets. - Requirements can change; use this as a traveller’s quick reference and confirm details in‑country.

How to buy and register smoothly (step‑by‑step)
- Decide eSIM vs physical SIM - Single or multi‑country trip? Consider Esim Western Europe or Esim North America. - Need calls/SMS? Some markets (e.g., Japan) require ID only for voice—data‑only eSIMs are simpler.
- Prepare documents - Keep your passport ready; jot down your hotel address and a local contact (hotel desk works).
- Choose the right channel - Airport carrier counters and flagship stores handle tourist KYC fastest. - For eSIM, complete the in‑app KYC with good lighting for any selfie/ID scan.
- Complete registration - Follow staff guidance or app prompts. Don’t leave until you’ve made a test call or used data.
- Keep proof - Save the receipt, SIM sleeve, QR code/eSIM email, and any confirmation SMS for the duration of your trip.
Pro tips from frequent travellers
- Arriving late? Pre‑activate an eSIM before you fly so you have data for ride‑hailing and maps on landing.
- Airport vs city: Airport kiosks are efficient but sometimes pricier than city shops; decide what you value more—speed or price.
- Brazil and Turkey specifics: Use official carrier stores; they’re set up for foreigner KYC and can explain CPF/IMEI rules.
- UK/US/Mexico: Even where registration isn’t mandated, keep your passport and a payment card handy in case a retailer requests verification.
- Keep it simple for teams: If you’re coordinating for a group or staff, consider centrally managed plans. See For Business. If you’re a reseller or TMC, explore our Partner Hub.
When an eSIM helps vs when it doesn’t
- Helps:
- Short trips where you want instant data without visiting a shop.
- Anonymous data‑only allowed (e.g., many Japan MVNO data plans).
- Multi‑country itineraries covered by regional products like Esim Western Europe.
- Doesn’t help:
- Markets requiring in‑person KYC before activation (e.g., China), or where tourist eSIMs still need document upload.
- When you specifically need local voice/SMS and the operator mandates full ID.
FAQ
- Do I always need a passport to buy a SIM?
- No. Some countries don’t mandate registration (e.g., US, UK, Mexico, Netherlands, New Zealand). That said, many sellers still prefer to see ID. When ID is required, a passport is the safest bet for travellers.
- Can I register online for an eSIM instead of visiting a shop?
- Often yes. Many European operators support video ID or document upload for eSIM activation (e.g., Germany, France, Italy, Spain). In some markets (e.g., China), you’ll still need to visit a carrier store.
- How long does registration take?
- In store: 5–15 minutes at airport counters, sometimes longer in city shops. Online/app KYC: usually 2–10 minutes if your photos are clear and documents match.
- What if I don’t have a local address yet?
- A hotel address is typically acceptable. If asked for a contact number, use the hotel’s front desk.
- Will my phone get blocked if I use a local SIM?
- Only in certain markets with IMEI controls (notably Turkey). Tourists can use their phones for a limited period (commonly around 120 days) without registering the device. This does not affect roaming on your home SIM.
- Is roaming on my home SIM affected by these rules?
- No. Real‑name rules apply to activating local SIMs/eSIMs. Roaming with your existing SIM works as normal, subject to your home carrier’s rates.
