Please help Crackberry Community! All of the sudden, I can't text. I sent tests to my husband's iphone, nothing. My friend is on Sprint, nothing. I click on a name in my address book, select SMS text, compose, send and I see the check mark. My messages are not being received. I have also not received any texts. I turned it off and removed the battery. I checked my settings, I have GSM. Any other ideas? Thank you!
