I am having a problem with text messaging with my Thrive phone. Randomly I stop receiving texts. I can take my SIM card out and put it in another AT&T phone and receive 20+ messages. The first time this happened, AT&T replaced my phone. I am having the problem again. I have cleared out the cashe but increased the limits in settings but I don't know what else to do. I send/receive 1000+ texts per month. Thanks for any help!!
