According to this thread: Bionic on tmobile - xda-developers Our Bionics are way more than just a Verizon forgotten deviced. Apparently it can be used on several systems. I have not tested this myself, but have been thinking about it seriously and using my Bionic with the StraightTalk $45 dollar plan.
Good luck!
I have my Droid Bionic XT875 (that I JUST got), and it's on Page Plus' $70 monthly plan. It shows full signal, but to the left of them, just "1X" with arrows below it, one pointing up, the other pointing down. I know 4G won't work with Page Plus. I'm fine with that. I just want 3G even! This phone is BEYOND slow and annoying when it comes to doing anything that uses mobile data. Can't use the internet much at all, and it just flat out sucks. I want to put it on Straight Talk ASAP, but I don't know if I would have to get a sim card from them, or get a pin card for CDMA activation. My phone has the original (I believe) 4G LTE sim card in it. If I took that out and put in an activated AT&T sim card, would it work and run on 3G, on AT&T? Sorry if these are dumb questions. This is my first Android phone. I had an iPhone 4S for about a year and a half. Any advice would be greatly appreciated! @dave52355 - how are you on Straight Talk? What did you have to do? If you could email me at [email protected] and let me know how you did it, step by step, I would Greatly appreciate it...I'm about to just sell this thing and go buy a $150 crapper from Straight Talk at this point. Thanks in advance!
