The SIM went from working to "Emergency Only" to "Unregistered SIM" and back to working again within a few hours. I was eventually able to get Google Voice to hear the DTMF confirmation code to register the number for use with Google Voice. So far, I can send SMS to just about number (smsBug, Google Voice, Cellular South) but have only been able to receive SMS from T-Mobile. I've been told that there is no provision for a SIM PIN, which is somewhat troubling, as I normally use a PIN.

All in all, I'm very hopeful about TelnaMobile. I've been concerned about what I will do after the demise of T-Mobile (one way or another). If TelnaMobile works well it will allow me to retain a viable international roaming capability while allowing me to solve my domestic service problem without having to consider international coverage.

P.S. I was able to receive a SMS from FishText.com
