Hello @Sarahfd ,
Welcome to the community,
Have you left your phone on? It has to be left on, otherwise the cellular watch will not work when out of range from bBluetooth.
I take it you have set up cellular correctly? You can check this on your watch either in settings or by scrolling up, it should show there, if not can you switch on to connect to cellular, you can also check via the watch app on your phone.
To contact EE customer service dial 150 from your mobile phone or ring customer service for free using Skype or another phone: +44 800 079 8586 or +44 800 956 6000.
