Hello. Since I moved to ID mobile in March, I sporadically am unable to make or receive phone calls. It doesn’t ring on their end if calling to me, and mine never rings out it’s just blank. I then turn my phone on and off and it works. I’m missing important calls from my daughters nursery so need this fixed asap. I have an iPhone 17 pro. Thanks!

Hi @HastedAlice,

I'm really sorry to hear you're experiencing issues with making calls. Please try the steps below and let me know if this makes any changes.

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,

Hi Gemma, thanks for responding. I actually transferred my number over so the correct number is under phone and when I deleted that out and just re-typed the same number it wouldn’t let me save as nothing had changed. Thanks!

Hi @HastedAlice,

Thanks for coming back to us.

Could you try entering your transferred number in the format +44 followed by your mobile number without the leading 0 (for example, +447123456789)?

Once the number has been saved, we'd also recommend performing a network settings reset.
