Phone: Droid 2 on PagePlusCellular Weirdest behavior ever. I can receive SMS from anybody. I can send messages to almost anybody. But to a few select contacts on my phone I can't send SMS, UNLESS they send me one first and I reply within 12ish hours. If I try sending those contacts an SMS 'from scratch', the phone tries and tries and tries and eventually comes back with a "Failure to send SMS message". There's no pattern on who I can send SMS to or not - some are T-MObile, some are AT&T, some are Sprint. WEIRD! Anybody got a clue what could be the cause? Thanks!
