This week my family swapped to T-Mobile and now we are not receiving any text notifications from our security system and have to keep verifying the numbers. I figured this would be an issue with the security system but after research this seems to be a T-Mobile issue. There are many with T-Mobile that are having this issue. I also have verified this by using another cell phone company to receive the text messages from my security system and he would receive them but i would not. All of our phones we just switch here do not receive the text messages. Is there anything on T-Mobile side that could be blocking the text messages? This is not a text message delay but just never receive them.
