Posting this in case it helps other people struggling to setup an O2 mobile data plan on their Apple Watch, ie to add an Apple Watch plan that is then associated with the tariff of their paired iPhone.
Tried to setup the mobile plan on 26th Dec 2022 but the plan was left permanently ‘activating.
After multiple lengthy phone calls to O2 support ( often hanging up rather than trying to help), multiple agonisingly slow messages to Twitter and Facebook Messenger, all subsequent retries were met with the message…
We're setting up your Apple Watch on the 02 network and we'll text you when it's all done. If you don't receive a text within 24 hours, call 202 for free from your 02 mobile, quoting reference code 08. (or in some cases code 90).
After nearly 8 weeks and with O2 Support no nearer resolving this problem, I tried a suggestion mentioned elsewhere on this forum to perform a sim swap.
Before inserting the new sim I unpaired my watch.
After inserting and activating the new sim I then ran through once again the mobile data plan setup.
This time, the process started as it should, prompted me to select the tariff, received SMS text with t&c’s link, acknowledged receipt, accepted conditions, received a confirmation text and plan was FINALLY setup correctly.
So lesson if you have the same problem, is to unpair your watch and try a sim swap on your phone. In spite of sceptics, it worked !
O2 Support please take note and use this information to get to the root cause. It is presumably sim related or possibly related to your new 360 system which seems to be causing huge headaches for customers and stores.
