I just switched from Sprint to T-Mobile...using a Nexus 4. I got really accustomed to using Google Voice on my Sprint phone. I originally downloaded it for the visual voicemail feature, but what I ended up using it for the most was the text messaging ability. I loved texting from the Google Voice web app, the Chrome extension or the Google Voice app on my WiFi-only tablet.
When I got Google Voice all set up w/ my new T-Mobile phone, though, I realized that SMS functionality wasn't available, at least using my own phone number (as opposed to a new Google Voice number). I downloaded MightyText, which seemed like a good replacement until I realized that it only works if my phone is turned on. That's kind of a bummer, because I really want to be able to text when my phone is off, dead, etc.
Does anyone know of a good Google Voice replacement for T-Mobile, or a way to get SMS working w/ Google Voice on T-Mobile. My phone is rooted and running Cyanogen Mod 10.1. Thanks in advance!
