Hi, i have been having constant issues with my Apple Watch Series 7 in that my O2 data plan seems to lose signal and keeps showing “No Connection” however today i have discovered if i leave my home for a walk and leave my iphone at home, as long as i dont lock the screen on my iphone, my watch keeps its cellular connection whilst im out? Has anyone else been experiencing this at all? Both iphone and watch are running the latest ios available. TIA
