im having trouble texting but it's only with one person, i send and receive messages to everyone else fine except for this one person. most of the time i wont get hers and she wont get mine, but she says nothing is wrong with her phone, and she texts everyone else fine except for me. is there anything i can do to fix this?

Probably need to talk to your carrier or she needs to talk to hers.

SMS is generally phone/carrier related, not BB.

okay, thanks!
