How do I port a UK number to Unlimit Mobile?

Enter your phone number, PAC code and postcode in the porting form and submit your request. Your current carrier may send you a verification message to approve the transfer; once you approve it, the port begins.

How long does it take to port my number?

Most UK mobile number transfers complete within one business day. In some cases it can take longer, depending on your current carrier and the verification process.

What information do I need to port my number?

Just your phone number, your PAC code and your postcode as registered with your current carrier. These details must match exactly to avoid delays.

What is number porting?

Number porting transfers your existing UK phone number from your current provider to Unlimit Mobile, unchanged. You keep using the same number for calls, messages and verification codes after you switch.

Are there any fees for porting my number to Unlimit Mobile?

Unlimit Mobile doesn't charge a fee for porting your number. Your current UK carrier may charge early cancellation fees or ask you to clear an outstanding balance first.

Can I port any phone number?

Most active UK mobile numbers can be ported, but eligibility depends on your current carrier and the number's status. Numbers that are inactive, restricted or tied to unresolved obligations may not be eligible.

Should I cancel my current plan before porting?

No. Don't cancel your current service before you start the port: your number must stay active for the transfer to succeed. Once the port completes, your previous service is usually cancelled automatically.

Can I port both prepaid and postpaid numbers?

Yes. Both prepaid and postpaid UK mobile numbers can usually be ported, as long as the number is active and eligible with your current carrier.

Will I lose my contacts or data when I port?

No. Porting only moves your phone number. Your contacts, messages and personal data stay on your device or in your cloud storage and aren't affected.

Can I track my port request?

Yes. Once you submit your request you'll get updates on the status of your number transfer, so you can follow its progress until it completes.

Will my service be interrupted while I switch?

Your current service stays active during most of the porting process. A short interruption can happen during the final transfer stage, but service is usually restored quickly once the port completes.

Do I need to buy a new phone?

Nope. Bring your existing unlocked iPhone, Samsung, Pixel or most modern Android devices.

Which devices support eSIM?

iPhone XS and later, Samsung Galaxy S20 and later, Google Pixel 3 and later, and most modern flagships support eSIM. Physical SIMs for the UK are coming soon.
