my phone wont send text messages to one certain person

[Music143]

So i have the LG ally, its been working great. though the battery doesnt stay alive for very long. Recently when i send a text to my friend, my friend doesnt get it. My friend has at&t. I dont understand why he wont recieve texts from me anymore. though i did drop my phone on a hard wood floor recently but i dont think that would have done anything. if anyone has any idea what is the problem please tell me! :heart:

What might be the problem is that you have a security setting that kicked in or something like that.

Facebook Mobile

If you have linked contacts with facebook mobile, you might experience this issue. Simply go to your contacts and unlink the facebook contact from the phone contact. This usually works.
