I can't send out text messages. No-one receives them. They don't show that they haven't been sent or fail to send. I get word from family members that they don't receive responses from me. They do, however, get my messages when I send them voice recordings. I receive everyone's messages just fine. Can anyone help me with this? I've gotten rid of anything I can think of. Cache deleted and re-started my cell phone. I appreciate any assistance with this.
