Resolved… I tried sending STOP and then START to 82539. That resolved my issue!
I have the same issue after switching from AT&T to T-Mobile. T-Mobile checked my account to be sure that short code texts were enabled, They assured me that they were, but I still cannot receive texts from the code 82539, the simplisafe short code.
