@Username50 , Yes, to use Apple Watch cellular, it is around £7.- a month with 10Gig of data, unlimited calls and text. It is an E-Sim, so just need to apply, which I believe you can do it when pairing the watch with your phone, but would need to have both connected to cellular and not wifi, hope this helps, otherwise if having a problem ring customer service and speak to them.
To contact EE customer service dial 150 from your mobile phone or ring customer service for free using web based app or another phone: +44 800 079 8586 or +44 800 956 6000.
