I got an HTC One M8 about a month ago, and everything has been working great. However, the last 2 or 3 days, I haven't been able to send MMS messages. I know that the numbers are correct, because I have been grabbing them straight from my contacts, and I have triple checked them. I've tried about 5 different pictures with 5 different contacts, and every time I do, a red triangle with an explanation point in the middle comes up saying "invalid destination address". I have no idea what happened, as it's been working up until the last few days. I have tried with and without WiFi, force stopped my messages and cleared the cache. Nothing works. Can anyone help, please?
