I've been using Boost for a few years now. I've had my i290 for several months and have been texting back and forth with the same person for most of that time. We've exchanged literally thousands of texts *which is why I have the unlimited plan XD* but suddenly this afternoon it doesn't want to work anymore. I keep getting Transport Error messages when trying to send a text or open one it says I have. Neither of us has changed phones so I'm not sure why I'm suddenly getting this error. All I can find it that it's a compatibility thing, but if that's the case why has it not been a problem for the past few thousand texts? Is there any way I can fix this?
