I'm having a situation where, when I send a text to one contact, my Thunderbolt will sometimes pick another contact - seemingly at random - and send the text to that person instead. I don't think I need to explain how that can cause real problems. I also had a similar issue with my OG Droid over a year ago, so I'm thinking it's not necessarily a phone-related problem, but a network issue instead. Has anyone else encountered this, and if so, are there any reliable fixes? I really need to be able to rely on my SMS to route my messages properly.
