I'm unable to call or receive calls when trying to communicate with someone regards to this you sent round with the webpage back and forth and when I was able to get a chat to support low and behold no response or acknowledgement for over 45minutes I recently paid up my previous contract off and upgraded to a new contract
The first day I had texts calls and data the next day nothing but data I assumed network errors but had no issues with masts or connectivity so why has this happened?
Sorry to hear of your troubles, @contract5.
A couple of docs to help, first off check your SIM works in another phone, if you can - your SIM may need a clean.
Check your MyO2 to see if the upgrade is complete.
Sounds like you have been through this guide: Guide: How can I sort out my network issues?
Lastly, numbers for O2 here to talk to someone, you can use Skype for the 0800 number: Guide: Coronavirus Community Help and Support - it is possible your new phone has been shipped with a call bar on it, which O2 need to remove. Call around 08:15, keep trying until you get on the queue with the music.
Track usage, upgrade and get support with the My O2 appDownload My O2
