I've been having the same problem where my messages don't "send". On my end it says my messages are "sending" but never "sent". However on the other end, whoever im texting receives multiple copies of that message. And sometimes VZ messages resends every text i sent that day so my friends receive a more copies of messages. why is happening. I called customer service and they had me clear the cache and data and im still having this problem.
