Countries that require SIM registration

Buying a local prepaid SIM without showing identification is now the exception, not the rule. The countries that require SIM registration outnumber the ones that do not on every continent, and over the last fifteen years the list has moved in one direction only. If you are landing somewhere for nine days and would rather not leave a passport scan in a shop you will never see again, the local SIM counter is the wrong door.

Registration is not one thing. It is a spectrum, and where a country sits on it decides how much of you ends up in a database:

• Sighted ID. The clerk looks at your passport and types a number into a form. Nothing is copied.
• Photocopy or scan. Your passport page is imaged and kept by the retailer, often on a shared drive, sometimes indefinitely.
• Central registration. Your identity goes to the carrier and, in many countries, into a state register that maps the number to you.
• Biometric capture. A fingerprint or a live facial scan is taken at the point of sale and matched against a national identity system.

The last two are the ones worth caring about. A number tied to your identity in a central register is a permanent, queryable link between a person and a device — and it outlives your trip by years.

Exact counts depend on who is counting and what they count — some tallies include voluntary schemes, others only statutory mandates. The organisations that track this seriously, Privacy International and the GSMA among them, have put the number of countries with mandatory prepaid SIM registration well above 150 for several years. That is most of the world.

More useful than the number is the direction of travel. Registration mandates are almost never repealed by the legislature that passed them:

• New mandates are introduced on security or anti-fraud grounds, and usually framed as proportionate and narrow.
• The requirement then ratchets: sighted ID becomes a scan, a scan becomes a central register, a register acquires biometrics.
• Reversals happen almost exclusively through the courts. Mexico’s biometric mobile registry, PANAUT, was struck down by its Supreme Court in 2022 — a rare and instructive exception.

Asia has the strictest regimes in the world, and it is the region where a tourist is most likely to meet biometrics at a phone shop rather than a photocopier.

This is also where the cost of getting it wrong is highest. In China a foreign number is hard to obtain at all and the domestic alternative is a facial scan. In India a tourist SIM can take a day to activate, which is most of a short trip. In Thailand the airport kiosk is genuinely fast, but your passport page goes with it. Pakistan takes a fingerprint. If you would rather do none of that, install before you fly — install and activate your eSIM covers the ten minutes it takes.

Where national identity systems are recent, they were often built alongside the mobile network rather than before it — so SIM registration and biometric ID arrived together, and the registration step inherited the biometrics.

Turkey deserves a specific warning that has nothing to do with privacy. Putting a Turkish SIM into your own handset starts a clock: after a set period an unregistered foreign IMEI can be blocked from Turkish networks unless you register the device and pay a fee. The rule is triggered by using a local line, not by being in the country — a foreign-issued profile roaming onto the same towers is not what it targets. If you are weighing that against simply leaving your home plan on, eSIM vs roaming covers the cost side.

Europe is not one regime. It is split roughly down the middle between countries that mandated prepaid registration — usually in the year after an attack — and countries that never did and show no sign of starting.

The practical effect is that a traveller crossing Europe can go from anonymous to fully registered by changing trains. The UK is still one of the easiest places on the continent to buy a prepaid SIM with cash and no name attached. Germany sits at the other end: verified identity has been required for prepaid since 2017, and the shop cannot activate the card until the check clears.

North America is unusually relaxed in law and unusually acquisitive in commercial practice. Latin America is close to the opposite: registration is generally mandatory, and increasingly biometric.

The US case is worth understanding precisely, because “no law requires it” is not the same as “nobody knows who you are.” You can still buy a prepaid SIM in the United States for cash with no identity check at the till. What follows is commercial rather than legal: the activation app wants an email, the top-up wants a card, and the carrier assembles the profile the statute never demanded. Brazil is the harder wall in the other direction — without a CPF tax number, a visitor is largely locked out of prepaid entirely.

This is the part the requirement never explains. Handing over a passport creates a record, and that record has a life of its own:

• It is copied more than once. The retailer keeps an image, the carrier receives the data, and in central-register countries the state gets a copy too.
• It is held by whoever sold the SIM. Often a franchise kiosk or an airport concession rather than the carrier — with the security practices you would expect of a franchise kiosk.
• It links a number to a person, permanently. Anyone who later obtains the number can work backwards to you, whether by lawful request or by leak.
• It is a breach waiting to happen. Telecom breaches routinely expose exactly this combination: names, document numbers, and the phone numbers attached to them.

None of this is exotic. It is the ordinary lifecycle of a document scan taken by a retail business in a hurry. The honest framing is that you are not choosing between privacy and surveillance — you are choosing how many organisations end up holding an image of your passport, and how long they keep it. What an anonymous eSIM hides — and what it cannot sets out where that choice genuinely helps and where it does not.

The list is short and shrinking, but it is real. As of 2026 you can generally still walk into a shop and buy a prepaid SIM without producing identification in:

• The United Kingdom — cash over the counter, no registration step.
• The United States and Canada — no statutory requirement, though carriers collect plenty during activation.
• The Netherlands and the Czech Republic — no mandatory prepaid registration.
• Several Nordic countries — no general mandate was ever introduced.
• Mexico — by court order rather than by policy, which is a weaker guarantee.

Two caveats, because they matter more than the list. First, “no ID required by law” does not mean no data collected: the activation app, the top-up card and the handset itself all leak identity even where the counter does not. Second, this list has lost members steadily — Hong Kong was on it until 2021 — and nothing in the trend suggests it reverses.

SIM registration laws bind whoever sells you a local subscription inside that country. A travel eSIM is not that. It is a foreign-issued data profile that reaches local towers through roaming agreements, exactly as your home SIM does when you land — and roaming visitors have never been the target of registration mandates, because they are already registered somewhere else.

• The reseller holds the carrier relationship, so there is no local buyer to register in the destination.
• The profile is data-only — no number, no voice, no SMS — which is the category that sits outside identity rules almost everywhere, Japan included.
• Nothing is purchased locally, so no shop in the destination ever sees your passport.

A no-KYC eSIM adds one further step: the store itself does not ask who you are either. Payment is a crypto invoice, the order is a random code, and there is no account for a travel history to accumulate against. That covers both ends — no foreign registration desk, and no vendor profile back home. A no-KYC eSIM for private travel walks through the trip-planning side, and the destinations list covers all 190 countries.

There is no free lunch in that table. The local SIM really is the cheapest per gigabyte in many countries — you pay for it with a passport scan and an hour of your first day. Roaming is frictionless and narrates your itinerary to your home carrier. The eSIM removes both problems and gives you no phone number in exchange. If you want the eSIM route measured against named competitors instead of against SIM cards, the comparison pages do that directly.

The entire point is that this happens before you are anywhere near a foreign counter:

1. 01
   Pick the plan size before you fly

   Packs run 1, 3, 5, 10, 20 and 50 GB, priced per country and valid for 30 days from the first connection.

2. 02
   Pay with crypto

   BTC, XMR, ETH, LTC, TRX, SOL, or USDT on ERC-20 or TRC-20. No name, no card, no account.

3. 03
   Get the QR in about two minutes

   It is issued against a random order token rather than an identity.

4. 04
   Install on Wi-Fi at home

   Install and test before you travel, so landing is one toggle instead of troubleshooting.

5. 05
   Land and switch it on

   The profile connects to a local partner network. No shop, no queue, no passport.

Sizing is the only decision that needs any thought — how much data do you need abroad? has the arithmetic for a week or a month. On the payment side, how to buy an eSIM with crypto covers the wallet steps if this is your first time paying that way.

Registration is one layer. Removing it does not remove the others, and any store telling you otherwise is selling you something:

• It does not hide your location from the network. Every mobile connection reveals which tower it is on. That is how cellular works, not a policy choice.
• It does not encrypt your traffic. Run a VPN or Tor over it if the content of your connection matters and not just who bought it.
• It does not give you a phone number. Data-only means no calls and no SMS — keep your physical SIM alongside for those.
• It does not exempt you from local law. What you do on the connection is governed where you are, exactly as with any internet access.
• It does not undo registrations you already have. If you have used a registered local SIM in that country before, that record still exists.
