I have the exact same issue I had no service for a whole day and now I still don’t have any service I’m tempted to which back

Hi ​@Christopherbonza and ​@Helloboss,

We're sorry to hear you're having issues following your switch.

​@Christopherbonza, As your eSIM appears not to have been received or installed successfully, we'd recommend contacting our Customer Service team as soon as possible. They can arrange for the eSIM to be re-issued and re-emailed to you. You can contact them via Live Chat here: https://www.idmobile.co.uk/live-chat.

​@Helloboss, if you have received your iD Mobile SIM, please make sure it is installed correctly and then try the following: 

For Android:

• Open Settings
• Tap General Management
• Tap Reset
• Select Reset network settings

For iPhone:

• Go to Settings
• Tap Phone
• Tap My Number
• Delete the old number
• Enter the new number
• 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 new SIM and verify your number.

Regards,

Gemma M
