Hi ​@Lee hadfield1988,

Sorry to hear you’re having trouble with your new iPhone, I can imagine how frustrating that may be. 

When moving a SIM from an old iPhone to a new one, it can sometimes take a little refresh for the network to pick up properly. First, it’s worth double-checking that you’re using the correct iD Mobile SIM card (and not the old provider’s SIM, if you previously switched).

Here are a few other things to try:

Make sure Airplane Mode is switched off
Restart your iPhone
Remove and reinsert the SIM card to make sure it’s seated correctly

Then try a network restart:

• Go to Settings
• Tap Phone
• Tap My Number
• Delete the old number
• Enter the new/current number starting with +44
• Tap Save

Then follow these steps to refresh iMessage:
 

• Go to Settings
• Tap Messages
• Turn iMessage OFF
• Go to Settings > General
• Tap Reset
• Choose Reset Network Settings
• Once your iPhone restarts, go back to Settings
• Tap Messages
• Turn iMessage ON again

Your iPhone should now recognise the SIM and verify your number.

After doing this, give it a couple of minutes as it may take a short while to reconnect to the network.

If it’s still not picking up a signal after trying these steps, allow 24 hours and then let us know if the issue is still persisting.
