Cellular data not working on my iPhone 14 Pro

I have an iPhone 14 Pro, yesterday the cellular coverage stopped working without clear reason. The top of the screen reads "5G+" and has full bars, yet there is absolutely zero connection, not a slow one, none (I tried an internet speed test and it cant even connect to anything). I have duel eSIMs, one from the UK and one from the US. I've been using the UK one in an American city of over 1M for over a year without issue.

• I've restarted the phone
• I've changed in and out of airplane mode
• I've swapped between US and UK data
• I've updated the phone
• I've reset the network settings
• I've toggled roaming
• Phone has been restarted after each of the above steps
• I've also spoken with both of my carriers and there is no known coverage issue

The phone hasn't been dropped (Least not for a few months),

Its amazing how frustrating this is, mainly because the phone still reads that I have reception. Does any one have any advice?
