Hi ​@fhj2015,

I'm sorry to hear you're having issues with calls.

From what you've described:

• Mobile data is working.
• The SIM is being detected by the iPhone.
• Network: Not Available is showing under the SIM details.
• There is no Voice & Data or 4G Calling/VoLTE option.
• Your phone number isn't showing in the settings.

Could you please try the following:

• Restart your iPhone.
• Remove and reinsert the SIM card.
• Ensure Automatic Network Selection is enabled:
• Settings > Mobile Service > Network Selection > Automatic
• Check for a Carrier Settings Update:
• Settings > General > About
• Wait for 30 seconds to see if an update prompt appears.

Reset Network Settings

• Go to Settings.
• Tap General.
• Select Transfer or Reset iPhone.
• Tap Reset.
• Select Reset Network Settings.
• Restart the phone.

If possible, also try the SIM in another handset to see whether calls work there.

If the issue persists after these steps, please contact our Customer Service Team via Live Chat so they can check the SIM provisioning and account status: https://www.idmobile.co.uk/live-chat
