Calls going to voucemail

I ported my number from o2 on 31st January. Calls are going to voicemail without ringing which is driving me mad as I have service according to my phone. I’ve tried restarting my phone, turning the e-sim off and on but to no avail. How do I resolve this?

Hi ​@Gemmasmyth,

I am so sorry that your calls are not working. May I please ask if text messages and data is working. If yes, please confirm the make and model of your device for me.

Thanks,

Yes texts and data seem to be working fine. I’m using an iPhone 16

Thank you ​@Gemmasmyth ,

Please follow the follow instructions as they will assist with having your phone recognize 0the ported number. If a step is correct, please move to the next one. Please switch off the wifi when doing these settings.
- Check have updated iOS
1. Update the correct number
* Go to Settings > Phone > My Number.
* Replace the temporary number you find there with your own number. use +44 instead of the first 0.
* Then tap Save.
Reset iMessage settings
Your iMessage settings won't reset themselves during porting - the temporary number will still be in your new iPhone.
To input your ported number into your new iPhone:
* Go to Settings
* Tap on Messages
* Tap iMessage ON
* Scroll down to Send & Receive number
* Replace the temporary number with your ported number
* Then tap Save.
2. toggle off imessage then reboot and then toggle on after 3-4 minutes and reboot the device
3. go to Setting -> Messages -> Click send & receive -> see if You
can receive imessage to and Reply from'
see if the correct number is displayed under Start new conversations
from and also advise to tick only on either his Mobile number or his email address to send iMessage
After doing all this advise to reboot the device and then try to start a conversation. If this does not work please contact Apple or try a replacement sim.

None of this has helped. I got a replacement sim which fixed the issues with iMessage but I am still not getting incoming calls or able to make outgoing calls…
