How do I move my phone number to a new phone by swapping the SIM card?
Answer
In most cases, moving your number to a new phone just means moving the same SIM card from the old phone into the new one. If either phone uses eSIM instead of a physical SIM, you may need to transfer the eSIM profile from carrier settings instead.
Before you start: stop right away if…
- Handle the SIM card gently; the gold contacts can be damaged by scratching or bending.
Follow these steps
Power off both phones
Turn off the old phone and the new phone completely before removing any covers or trays.
You should see: Both phones are fully powered down.
Remove the SIM card from the old phone
Open the SIM tray or back cover on the old phone using the tool that came with it, or a small pin, and take out the SIM card.
You should see: The SIM card is out of the old phone and not damaged.
Insert the SIM card into the new phone
Place the SIM card into the new phone's tray or slot in the same orientation shown in the tray, then close it.
You should see: The tray or cover clicks or slides back into place.
Turn on the new phone and check for signal
Power on the new phone and wait a minute or two for it to connect to the network.
You should see: Signal bars or a carrier name appear at the top of the screen.
Test calls and texts
Send a text message and make a short test call to confirm the number works on the new phone.
You should see: The text sends successfully and the call connects.
Use eSIM transfer if there is no physical SIM
If either phone only supports eSIM, open the carrier's app or the phone's cellular settings and look for a 'Transfer eSIM' or 'Convert to eSIM' option instead of moving a physical card.
You should see: The new phone shows an active eSIM connected to your number.

Extra tips
What to look for: Whether both phones use a physical SIM card, or whether either phone requires an eSIM.
Before you change anything: Confirm whether your phones use a physical SIM, an eSIM, or both. Back up contacts and photos on the old phone before making changes. Confirm you are using the official carrier app or website for any eSIM transfer. Never share your account password with anyone.
