@Steveparker74 You can but they will not get cellular data as they’ll need to set up a cellular data plan on O2 to have data. So that means you’ll being paying EE for the watch contract and they’ll be paying to have a cellular plan on O2.
Your other option is to get a watch only contract so they have a watch with cellular on EE but the watch will have it’s own phone number on EE but the watch can still be paired with the O2 phone but it will not ring when someone calls the phone if the phone is not with them. The name of this plan is the Family member plan and it’s the most costly option.
To contact EE Customer Services dial 150 From your EE mobile or 0800 956 6000 from any other phone.
