Hi, I have a service that reminds people to move their car on street sweeping days (dontfearthesweeper (dot) com). It sends a text message the night before your street sweeping. Everyone I send messages to signed up for the service, and they have the option to stop getting messages at any time.
It has come to my attention that tmobile is blocking my messages. As far as I can tell tmobile is the only carrier that blocks the messages. How do I fix this situation?
I spoke with several people in customer support. I heard over and over again that I had to be a tmobile customer to get support on this issue. So I’ve bought a tmobile account just to get help with this. I’ve confirmed on my new tmobile phone number that my messages are being blocked. The first message went through, but after that the rest of the messages were blocked.
The messages are being sent through a normal (not short code) phone number with twilio. I’m sure they’re following all the appropriate procedures. I’ve seen people mention needing to use a short code phone number which is prohibitively expensive (1000’s of dollars per year) for a service I provide for free.
