Good morning, tommyguns69!
Let's see if we can figure out what's going on. Have you ever been able to send texts using this device? If you move locations (more than 10 miles away), are you able to send texts? Are you connected to WiFi when this is happening? Lastly, please take a look at the steps found here and give those a shot to see if that works to restore texting on your phone.
It's me again! Just wanted to swing by to see if you've had a chance to look over my previous reply from a few days ago. If everything is good to go, great! If you're still having issues, please get back to me with answers to the above questions.
