Just started today that I cannot send or receive picture messages. I have also been getting a lot of network failure notices when trying to send texts. Also, I have been getting a lot of messages from other people about 4 hours after they sent them, even when I have full service! I did just activate a $20.00 unlimited messaging card yesterday, but that isn't supposed to take effect till Nov. 1st. And that still doesn't explain why I've been getting the Network Failure notices and the delayed messages. Can anyone enlighten me on why this is happening?
