It can take up to 24 hours to activate a SIM card or an eSIM.
If you've just upgraded to a new device, and your old SIM still fits, switch back to your old SIM card – you don't need to use the new SIM we've just sent you.
What kind of SIM do you have?
I have a physical SIM card
If it's been more than 24 hours and you still don't have service with your new SIM:
- Check your email – we may have sent you an update with instructions to follow
- Remove and reinsert your SIM – then restart your device
- Activate your SIM – if you're using the new one we sent you
- Use the network status checker – see if there are any network issues in your area that could stop activation.
If you reported your device lost or stolen:
- Remove any bars on your account – your device might still be blocked
If you're joining from another network:
- Check if your device is locked – if your device was used on another network, you need to contact your previous provider to unlock it
- Check your transfer completion date – if you're bringing your number over from another network, it won't work before this date
I have an eSIM
- Check your email – we may have sent you an update with instructions to follow
- Make sure your iPhone has signal and is paired with your smart watch
- Restart your device
If none of those things work, please chat to us online or find out how to order a replacement SIM
