Hi @Samiworld

It sounds like the SIM has not been activated and so is not connecting to a network.
To check, verify the network name: Under the network information, in the phones Settings, you should see that iD Mobile is listed as your network

Is this a new SIM due to transferring from a different network or a replacement SIM for a current account?

If you are new to iD Mobile then here is some advice:-

If you are transferring from another network, are you trying to use the SIM before the selected switch date? Your switching date can be found in your Order Complete email or Contract Summary. If you're new to iD, your SIM will arrive pre-activated and you can use it straight away.

Or you can try this link to activate the SIM:-

If it is a replacement SIM then it needs to be activated:-

Other things to try:-

1. Basic Troubleshooting

Restart Your Phone:

Turn your device off and then on again to allow it to reconnect to the network.

Check SIM Placement:

Power off your phone, then carefully remove and reinsert the SIM card to ensure it's seated correctly in the tray.
Clean the SIM:

Gently wipe the metal contacts on the SIM card with a clean, lint-free cloth.

2. Test the SIM and Phone

Try in Another Phone:

Insert the SIM into a different compatible phone to see if it works. If it works in the other phone, the problem might be with your original device.

Check for Physical Damage:

Inspect both the SIM card and the SIM tray for any signs of dirt, debris, or damage.
