Getting a new phone? Your number can come with it. Transferring a phone number to a new device is usually quick — the details depend on whether you use a physical SIM or an eSIM, and whether you are staying with the same carrier. Here is how to move your number to a new phone.
Key takeaways
- Same carrier + physical SIM: often just move the SIM card over.
- eSIM: transfer digitally during setup or through your carrier's app.
- Switching carriers: you 'port' your number using account details and a PIN.
- Back up contacts and re-register iMessage so nothing gets lost.
Before you start: back up
Moving the number is separate from moving your data. Make sure your contacts, photos, and messages are backed up first (iCloud or Google), so the new phone restores cleanly.
Same carrier, physical SIM
- 1Power down the old phone.
- 2Remove the SIM tray, move the SIM into the new phone, and power it on.
- 3Wait for the network to connect; restart if you don't see signal.
Transferring an eSIM
Most modern iPhones use eSIM, which has no card to move. Instead you transfer it digitally.
- 1During new-iPhone setup, choose to transfer your eSIM from the nearby old iPhone when prompted.
- 2If you skipped setup, go to Settings → Cellular → Set Up Cellular / Transfer.
- 3Or use your carrier's app to activate the eSIM on the new device.
Switching to a new carrier (porting)
Keeping your number while changing carriers is called porting. You do it through the new carrier — never cancel the old account first, or you can lose the number.
- 1Gather your account number and transfer PIN from the old carrier.
- 2Give those to the new carrier when you activate service.
- 3Keep the old line active until the port completes (usually minutes to a day).
After the transfer: don't skip these
- Re-register iMessage and FaceTime (toggle off and on in Settings).
- Confirm two-factor codes arrive on the new phone.
- Check that your contacts restored correctly.
Kept your number? Then your contacts are fine — this time
Transferring your number means you don't have to tell anyone. But the day you dochange numbers — or move, or switch jobs — every contact's copy of your info goes stale at once. Social Contact keeps your details in one profile so a change reaches everyone automatically. See how.
Frequently asked questions
How do I transfer my number to a new phone?
Move your physical SIM, transfer your eSIM during setup, or — if changing carriers — port the number through the new carrier using your account number and transfer PIN.
