Apple Watch paid off

[Morgan25]

I just finished paying off my Apple Watch. What happens now? Do I need to contact o2 to do pay as you go for it or something? Will my bill just reduce by the device plan amount but continue with my tariff amount?

I have an apple watch series 7 with GPS/ cellular.

Yes to "Will my bill just reduce by the device plan amount but continue with my tariff amount?"

You'll still have a plan for your watch, which will continue at £7/month until you cancel it, @Morgan25 - you can call 202 or contact O2 via X or Insta or Facebook as in here: Guide: How to find help & contact O2 to cancel if you wish. Apple Watches and PAYG don't mix on O2. Good luck @Morgan25.
