Cant get SimpliSafe SMS Alerts on my Apple Watch 4 LTE - Family Sharing - but every other text I get on watch from other people
My Apple Watch 4 LTE has a separate phone # from my iPhone - and is on Family Sharing.
I can get any other text message on my apple watch but for some reason SimpliSafe can't text me. The Apple Watch plan I use is through TruPhone - I asked them what carrier they use and its T-Mobile. Please help. I cannot verify my Apple Watch 4 phone number with SimpliSafe.
