Temp Phone Numbers for Expats: Bridging the First-Week Gap Abroad

The Two Halves of the Problem

Expats hit two separate failures at once. The first is inbound: local apps want a local number. Bolt in Tbilisi, Glovo in Lisbon, Wolt in Warsaw, Careem in Dubai, Grab in Bangkok, and every local classifieds site check the country code at signup, and a foreign number is either refused outright or accepted and then blocked at the payment step. The second is outbound from your old life: your home bank, your home government portal, your old email, and your old marketplace accounts keep sending codes to a number that is now roaming at a euro per message or has stopped working altogether.

The two halves need different products. The local half is a series of one-off activations in the new country. The home half is a long-term rental in the old country, held for as long as you need those accounts to keep working. Trying to solve both with one number, or with a shared public inbox, is how people lose access to accounts in both places.

The First-Week Gap: Local Apps Before a Local SIM

Getting a local SIM is not instant in most of the countries expats move to. Portugal requires a passport and usually a NIF for a contract; prepaid is easier but still registered. The UAE requires an Emirates ID or a visa-stamped passport for a full SIM, with tourist SIMs limited in validity. Thailand registers every SIM to a passport at the point of sale, which is easy, but the queue at the airport kiosk is not where you want to be with luggage. Georgia is one of the easiest, with prepaid SIMs from Magti, Silknet, or Cellfie sold on a passport in minutes, and even there you may land at night.

In the meantime you need a ride from the airport, groceries delivered, and a way to message the landlord. That is a handful of signups, each needing one SMS code on a local number, and each of them is an activation on TempNumber.me. Pick the country, pick the service, receive the code, and the account is created. The accounts that need a persistent number later, such as the local bank, wait for the real SIM.

• Georgia (+995): Bolt, Glovo, Wolt, and the myauto.ge and ss.ge marketplaces. Numbers at /georgia-phone-number.
• UAE (+971): Careem, Talabat, Noon, Dubizzle, and Deliveroo. Numbers at /uae-phone-number.
• Portugal (+351): Bolt, Uber, Glovo, OLX, and Idealista for the apartment search. Numbers at /portugal-phone-number.
• Thailand (+66): Grab, LINE MAN, Foodpanda, Lazada, and Shopee. LINE itself needs a local number to register and is how landlords and agents communicate. Numbers at /thailand-phone-number.
• Poland (+48): Bolt, Uber, Wolt, Pyszne.pl, OLX, and Allegro.
• Spain (+34): Cabify, Glovo, Wallapop, and Idealista.

Keeping Home-Country 2FA Alive

The accounts you leave behind do not know you moved. Your old email, your old marketplace seller account, your old streaming subscriptions, your old social accounts, and, if you are unlucky, your old bank all send SMS codes to your old number. Once roaming lapses or the prepaid SIM expires, those codes stop arriving. Keeping the old SIM alive from abroad is possible but fragile: many prepaid SIMs die after 90 to 180 days without a top-up, and carriers reclaim contract numbers when payments stop.

The durable fix has two parts. First, before you leave, move every account that supports it to an authenticator app or email 2FA, so SMS is a fallback rather than the only route. The method is at /blog/two-factor-authentication-without-phone. Second, for the accounts that insist on SMS, update the phone to a long-term TempNumber.me rental in your home country before your old SIM dies, and keep the rental renewed. A private rental delivers the code to your dashboard from anywhere, and because the number is yours alone for the rental period, nobody else sees the codes.

Do the number change while the old SIM still works. Most platforms send a confirmation code to the old number when you change the phone on file, and if the old number is already dead you are into account recovery, which is slow from abroad and sometimes impossible without a local address.

What Not to Move to a Temp Number

For banks and government portals, get a real local SIM. Bank 2FA is the account that can move your money, and a bank's fraud team treats a number change as a risk event; some, including several UK and German banks, only allow a phone change in branch or by post. Moving bank 2FA to a rental that you might forget to renew is worse than keeping it on the old SIM until you have a proper replacement. Tax portals, immigration portals, and national digital-ID schemes such as Portugal's Chave Movel Digital or the UAE's UAE Pass are tied to a registered local SIM by design and will not work on anything else.

For those accounts, the sequence is: keep the home SIM alive by topping up until you have the new local SIM, then update the bank to the new SIM directly. A rental is the bridge for everything else, not for the accounts that carry legal weight.

Activation or Rental: The Expat Split

A short table, described in text. Local ride-hailing, delivery, and marketplaces in the new country: activation. Local bank and government: real local SIM, wait for it. Home email, social, streaming, and old marketplace accounts: home-country rental, plus authenticator where possible. Home bank: keep the old SIM until the new local SIM exists, then move it directly. Home government portal: whatever SIM you registered with; do not move it to a temp number.

The general travel version of this split, for trips rather than moves, is at /blog/temp-number-for-travel. The expat case differs in that the home-country rental may run for years, so plan for renewal rather than treating it as a one-off.

Common Mistakes

The mistakes below come up repeatedly in expat forums, and each has a straightforward avoidance.

• Letting the old SIM die before moving accounts. Change the number on every SMS-2FA account while the old SIM can still receive the confirmation code.
• Using a shared public SMS number for the first-week apps. Bolt, Glovo, and Wolt reject them, and any code that arrives is visible to everyone on the page. A private activation costs little and works.
• Using an activation for the local bank or for anything with payouts. Those accounts send codes for months; an activation is released after one.
• Forgetting that the home rental has an expiry. Set a calendar reminder a week before, and renew. A lapsed rental cannot be recovered.
• Moving the home bank to a rental. Keep it on a real SIM in one of the two countries.
• Registering local WhatsApp on an activation when the local number is going to be your contact number for years. WhatsApp re-verifies on every device change; use the real local SIM for the WhatsApp you give to people.

A Sequence That Works

Two weeks before departure: move every account that supports it to an authenticator app, and update the SMS-only accounts to a home-country TempNumber.me rental while the old SIM still works. Keep the old SIM topped up. On arrival: use activations in the new country for the ride, delivery, and marketplace apps you need immediately. First week: get a local SIM with your passport and, where required, your permit or tax number, and put the local bank, the government portals, and your contact WhatsApp on it. Ongoing: renew the home rental on schedule and let the old SIM lapse once the home bank has been moved to a SIM you control.
