Switch from Three to iD Mobile
Keep your phone number when you switch from Three to iD Mobile. Here's how in 3 simple steps.
Important Warning
Do NOT cancel your contract manually. If you cancel before transferring your number, you will lose it permanently. Your old contract will automatically cancel once the transfer completes.
Pre-Switch Checklist
- Back up your data: Contacts, voicemails, and saved messages won't transfer.

How to Switch from Three to iD Mobile
Get your PAC code from Three
Text PAC to 65075 from your Three phone. You'll receive your PAC code by text within a minute.
You can also call Three on 333 (or 0333 338 1001 from another phone).
Give your PAC to iD Mobile
Sign up for a iD Mobile plan and give them your PAC code. You can usually do this online at my.idmobile.co.uk, in-store, or by phone.
Wait 1 working day
Your number will transfer from Three to iD Mobile within 1 working day. You'll get a text when the switch is complete. Your old Three contract is automatically cancelled.
Transfer Cut-off Times: Submitting your PAC code before 5:30 PM usually means your number will transfer the next working day. Submitting it after 5:30 PM or on weekends/bank holidays will add an extra working day to the process.
Final Bill: You'll receive a final bill from Three shortly after the transfer is complete. This covers your usage up to the date of the switch.

Things to Check Before Switching
- Contract status — Check if you're still in contract with Three. You can switch at any time, but you may need to pay an early termination fee if your minimum term hasn't ended.
- Outstanding balance — If you're paying off a handset, you'll need to settle any remaining balance with Three.
- Phone compatibility — Make sure your phone is unlocked and compatible with iD Mobile's network. Most phones sold since 2015 are unlocked.
- Coverage — Check iD Mobile coverage in your area before you switch.
Same Network Coverage
Three and iD Mobile both use the Three network, so you'll get the same coverage after switching. No need to worry about signal changes.
