I have a dumb phone that was on AiO Wireless (part of AT&T) that has now become part of Cricket Wireless (also part of AT&T). I have tried to both AT&T and Cricket in the Alarm.com interface to allow the phone to receive text messages, but neither setting seems to work. I receive texts on it all the time from other cell phone users as well as from things like Amazon delivery tracking, UPS tracking, etc etc. The other cell on my account, which is with another carrier (Net10) works perfectly when AT&T is selected (they are an AT&T reseller). Can anyone advise how I can go about troubleshooting this issue?
