Apple Watch data plan (error 14)

[2023_]

Since I’ve had my Apple series 8 Watch I have intermittent data when I’m away from my phone (Bluetooth connection). 
I did a soft reset as suggestion via chat. Did nothing.

today I tried a hard reset!! My watch then literally became useless as was stuck on the setting up screen to setup a data connection and then getting error code 14. 
called technical at o2. She didn’t have the foggiest what to do, kept going on about choosing the option to setup a new connection. There is no option. 
please help!! I need to get my watch data back as I often go out without my phone (dress wearing season!) 😁

Hi @2023_ - simplest way to get this moving is to engage an O2 Advisor here on the Forum - @O2Sarah- is on from 8am Tuesday morning, if you can keep a watch for a private message from her to get the details, that would be great. Good luck!
