OK...I dunno what's going on but this just started today. I am able to receive images via texting from my contacts (mms) but now out of no where they are not receiving mine. I am on wifi and when I send an image the 4G kicks in (which is what it's suppose to do but the other get's nothing. They receive my txt's but no image. I have a Samsung Galaxy Ace II x. Is my phone defective or is it the network? No settings have been changed as I have verified this. I even took off the wifi and just ran the 4G with the same results. No images can be received to any of my contacts even though it says it was sent by MMS to them. I even set up the APN manually with no change. Like I said this just started out of nowhere.
