You can put your sim in any phone you want. No need to tell O2.
If you change your watch, you will need to link it with your phone which should be a simple as resetting the watch then re-pairing it, however, this does not always go smoothly so help from O2 to reset things at their end may also be required.
I have no affiliation whatsoever with O2 or any subsidiary companies. Comments posted are entirely of my own opinion. This is not Customer Service so we are unable to help with account specific issues.
Please select the post that helped you best and mark as the solution. This helps other members in resolving their issues faster. Thank you.
