Gated Community Call Box No longer calls my cell
So we have a call box out front where you locate the residents name and then dial them to get the front gate opened.
it has worked perfectly up until last month when we noticed it stopped dialing in. I have called att and they said they turned on WAP PUSH but still nothing.
Tried contacting the gate builder/directory box manufacturer and they said it is a carrier issue.
I am using iphone X 15.5
not sure what happened after last month that made my phone unreachable.
