New phone. Physical SIM not working

I’m paying for an iPhone 15 which is fine and I’ll continue to do. But I have access to an iPhone 17. I’ve transferred the physical sim into the iPhone 17 but mobile data isn’t working. Neither are calls and texts.

Hi @Lawrie3112,

We're sorry to hear you're having trouble using your SIM in the iPhone 17.

Please could you try the below troubleshooting steps:

Go to Settings.
Tap Phone.
Tap My Number.
Use the delete button to remove the old number.
Use the keypad to enter the new number.
Tap Save.

Go to Settings
Messages
Turn off iMessage.
Go to General
Reset
Reset Network Settings.
Once the iPhone is open.
Go to Settings
Messages Turn ON iMessage.
This will recognize the new sim and have it verified.

If the SIM still doesn't work in either device after trying the above, please contact our Customer Service team via Live Chat so they can run checks on your line and arrange a replacement SIM if needed.
