You’ve found a flat, booked the flight and packed the boxes. Your UK phone number is easy to forget on that list, until the first time your bank sends a security code to a number you no longer have.
A UK mobile number is tied to your bank, HMRC, pension, GP, insurers, delivery services and dozens of online accounts. If it stops working after you move, you can be locked out of accounts that are hard to recover from overseas.
This guide covers the options for keeping a UK number when you move abroad, what each one costs you in money and hassle, and how a UK eSIM like Megaconnect, available on the App Store and Google Play, gives you a +44 number that works wherever you live.
Why Your UK Number Matters After You Move
Security codes
UK banks, building societies and many online services send one-time passcodes by SMS when you log in, add a payee or pay online. No number, no code.
Account recovery
Email and social media accounts often use your phone number to recover access. Losing the number can mean losing the account.
Official and financial contacts
Tax, pension, insurance and investment providers use your number to verify who you are when you call.
Staying reachable
Family, friends, former colleagues and landlords already have your UK number. Keeping it means nobody loses touch.
Number recycling
Operators can reassign numbers that stay inactive for a long time. If that happens to your old number, someone else could receive texts meant for you.
Your Options for Keeping a UK Number
Option 1: Keep your current contract
The simplest option on paper, but often the most expensive. You keep paying a monthly bill for allowances you won’t use, may pay roaming charges abroad, and are tied to the contract terms. Check whether your contract allows use abroad for long periods, since many plans are designed for UK residents.
Option 2: Switch your current number to pay-as-you-go
Many UK operators let you move an existing number to a cheaper pay-as-you-go plan. You keep the same number, but you must follow the operator’s rules to keep it active, often a top-up or some usage every few months. Rules differ between operators, so check them before you leave. You also need your physical SIM in your phone, or a dual SIM phone, for texts to arrive.
Option 3: Get a new UK number on an eSIM
If you’re ready to update your accounts, a UK eSIM gives you a real +44 number that runs next to your new local SIM, with no plastic card to keep safe. You add the new number to your bank and other services before you move, and from then on everything arrives on one phone, wherever you are.
Option 4: A virtual (VoIP) number
Cheap and quick, but many banks and apps reject VoIP numbers for security codes. Not a safe choice for your main contact number.

| Works next to a local SIM | Needs dual SIM | Needs dual SIM | Yes | Yes |
| Receives standard SMS | Yes | Yes | Yes | Sometimes |
| Easy to keep active from abroad | Yes | Depends on operator | Top up once every 180 days | Yes |

Moving-Abroad Checklist for Your UK Number
Start this about a month before you move:
- List every account that uses your UK number: banks, credit cards, HMRC, pension, insurance, email, social media, delivery and shopping accounts.
- Decide which option you’ll use: keep your old number on pay-as-you-go, or get a new UK number with Megaconnect.
- If you get a new number: Download Megaconnect from the App Store or Google Play, install the eSIM and check that it receives texts.
- Update your accounts while you’re still in the UK. Changing a number is usually easier when you can still receive codes on the old one.
- Test your bank logins with the new number before you cancel anything.
- Only then cancel or downgrade your old contract.
- Set a 180-day reminder in your calendar for your next top-up.
Visiting the UK After You Move
When you come back to visit family or for work, buy a UK data plan in Megaconnect for the length of your stay. Your number stays the same, and you get local data without roaming on your new country’s SIM.
When you travel to other countries from your new home, pair it with Megaroam for local data in 200+ countries. Crossing several borders? Read our regional eSIM guide.
Tips
- Label your lines: “UK” for Megaconnect, and your new country’s name for your local SIM.
- Keep the UK line switched on so texts arrive, even when you use your local SIM for data.
- Don’t delete the eSIM profile. Removing an eSIM usually can’t be undone.
- Top up before 180 days pass. A calendar reminder is the easiest way.
