Just got off the phone with SSA help desk. Her first question was am I using T mobile? Apparently many T mobile customers find their SMS blocked. (T mobile offers text message blocking for customers billed for each message). That is not my issue, however.
Help desk lady said that SSA’s history indicates that a message was sent, so they are not blocking messages to VOIP. However, I used my Google Voice number. It worked in August, but not now. After reading through the messages here I tried texting “Help” to 79913 using Google Voice - no response. Tried again using the RW number (which is T Mobile) and got an instant reply.
I requested a change. When the snail mail letter comes in a week or so I will set up both email and the RW number. I like belt and suspenders, and would add rope if I could.
I also had a chat with Wells Fargo last summer. No GV or RW, or even email for certain services like Zelle. Only work around is to buy a fob from them that displays a code that changes every 60 seconds. I have used them in the past to log in to my employer’s VPN and they work. But it’s a pain in the posterior. I changed banks instead; that’s only a one-time pain.
