LG Optimus One I can't seem to send or receive MMS. I've checked the forum and the solution seems to be enable your data, but I always have my data on and it doesn't solve anything. For the first few months, I had a little difficulty with MMS but not a lot. After that, I just stopped being able to send or receive MMS completely. I've tried using data, wifi, and both. When I hit download, it stays at 0% anywhere from a few seconds to a few minutes, then just stops or says it was unable to download.
