Apple Watch shows “no connection”

[Terbium]

I had my Apple Watch Series 5 working perfectly with o2 for around 3 years. Recently, the watch was replaced by Apple after developing a problem. Before giving the old watch to Apple I was sure to properly reset it, including removing my data plan from the device. I then setup my replacement watch and successfully added my data plan onto it. Everything seemed to work fine at first but after a few hours something strange started to happen. My watch would connect to the o2 network and show bars of signal, but under status it would say “no connection.” I could make calls on the o2 network but mobile data had effectively been disabled (so no Siri, no music streaming etc etc). I discovered that if I restarted the watch, then briefly everything would work fine again, but within hours the same issue would return. Apple ran some diagnostics and confirmed that the watch is fine and the problem lies with O2. I decided to remove my data plan from the watch and try re-adding it. When trying to re-add the plan, I was getting an error page from O2 saying to call customer service and quote reference code 14. Initially, O2 had no idea what this meant but id read online that resetting the esim might work and so I asked them to do that. It worked and I was then able to add the data plan back onto the watch. Unfortunately, I’ve now come full circle and I’m back to having my data plan on the watch but I’m getting this strange problem that requires restarting the watch to fix.

Please could someone end my suffering and help me solve this. Beyond what’s already been written, I’ve also tried resetting my new watch and resetting my phone.

I have the exact same problem on my Apple Ultra watch.  I've just spent 48 very frustrating minutes on the phone to O2 who are unable to fix it

I removed the plan from my watch and reset it.  No luck

Apparently support will get back to me within 5 days!

This can't be that complicated to make the data aspect work

Did they ever fix this for? you and if so how?

I have this same issue with the no connection status. I have a monthly sim only plan with the Apple Watch sync added. Have an Apple Watch Series 5 with cellular also iPhone 14 Pro… my plan only works whenever I am near to my mobile. I’ve switched to 02 recently and would like this fixed.

@kcn2024 - you stand a better chance of a reply if you post afresh rather than tagging a note into an old thread.

In your case, take phone, watch and photo id into an O2 Store, let them take a look for you. If you are still in your 14 day cooling off period, be prepared to cancel with O2 and go with another provider, O2's history on iPhone and watch pairing is dismal (as a search of the forum here will reveal to you). Good luck!
