I have a rather strange issue that has left me completely stumped. While I'm on a phone call and (at the same time) texting back and forth with someone else, I start receiving blank text messages that appear to be from no one. The sender is blank and the message itself is blank. I've searched on here and other BB websites and can't really find anything so I was hoping someone here could help. It doesn't happen 100% of the time, but often enough that it's fairly annoying. It doesn't happen with one particular person either, I could be texting one of my friends on AT&T or another person from T-Mobile. Any help would be greatly appreciated!
