Moving Abroad: How to Handle Your First Month Before You Have a Local Number
Relocation has a connectivity gap between landing and getting a local contract, and almost every administrative step in between needs a working phone. Here is how to bridge it.
Moving to another country involves a sequence of appointments — housing, bank, residency, tax number, health cover — and almost all of them want a phone number, an internet connection, or both. Meanwhile, getting a local phone contract usually requires the very documents you are trying to obtain.
A travel eSIM is the bridge. Here is how to use it well.
Why the first month is the hard part
Typical requirements in many countries:
- A local SIM contract wants a local bank account or proof of address
- A bank account wants proof of address and often a local number
- Proof of address requires a rental contract
- A rental contract requires a bank account, references, and a number the agent can call
Prepaid local SIMs are sometimes the way out, but in several countries they also require registration with a local ID or a tax number.
The bridge setup
Travel eSIM for data, from the day you land. No local ID, no bank account, no address.
Your home SIM stays active for calls and SMS, because your home bank will keep sending codes there — and you will need your home bank until the local one exists.
Data roaming off on the home line, on for the eSIM. Settings walkthrough.
Size the plan for a heavy month: relocation admin involves constant navigation, forms, video calls with agents and long hold times. 15-20 GB is a sensible starting point, with the option to top up.
The order to do things in
- Land with working data. Install the eSIM before you fly — why.
- Get temporary accommodation sorted first, even if it is short-term. Most things downstream need an address.
- Open a bank account. Several online-first banks accept foreign documents and a foreign number, and can be opened before or immediately after arrival. This unlocks most of the rest.
- Register your address with the local authority if the country requires it. This is often the key that unlocks everything else.
- Get your tax or ID number.
- Then get a local SIM. By now you have what they ask for.
- Keep the eSIM profile installed as a backup and for trips home.
The order varies by country, but the principle holds: the eSIM removes connectivity from the critical path so you can work on everything else.
Keeping your home number
Do not cancel your home line during the move. You will need it for:
- Bank and brokerage two-factor codes
- Accounts tied to your old number (some cannot be changed remotely)
- Family and friends who will keep calling it
- Anything that requires proving continuity of identity
Once you are settled, move your important accounts to the new number deliberately, one at a time, then decide whether to keep the old line on a cheap tariff or port it to an online service.
If you are an EU citizen moving within the EU
Your home SIM works at domestic rates under roaming rules — but only for a few months. Permanent-roaming provisions exist specifically to stop people living abroad on a foreign tariff, and your operator can apply surcharges after a warning.

Practical first-week list
- Offline maps of your new city
- The local emergency number
- A translation app with the language downloaded offline
- Screenshots of your address in the local language, for taxis and delivery
- Your documents in cloud storage and offline on the phone
- Public transport app and payment method
- A note of which power sockets and voltage the country uses
FAQ
How long can I use a travel eSIM for? Plans have validity windows, typically up to 30-90 days, and can usually be renewed. For a permanent move, it is a bridge, not a destination — local plans are cheaper long-term.
Will I get a local number with it? No — travel eSIMs are data-only. That is fine for the bridge period, because WhatsApp and email cover most communication.
What if a local service refuses my foreign number? Some will. That is the main reason to get a local SIM once you can — until then, use email and in-person appointments.
Should I port my home number? Consider it after you are settled, not during the move. Porting mid-relocation can lock you out of two-factor codes at the worst moment.
The bottom line
Land connected, keep your home number live for codes, use the eSIM to get through the appointment sequence, then switch to a local plan once the paperwork exists. The bridge only needs to last a month — but without it, every other step takes longer.
