I am currently on AT&T using an unlocked T-Mobile Samsung Exhibit II without a data plan. I find no use for the plan, im around W-Fi 99% of the time. Im on the Family Unlimited Messaging Plan ($30.00) that allows me to send unlimited txts, and picture messages. Can someone provide me with the correct APN settings for MMS only. I want to make sure I have MMS working but I dont want any accidental data charges on my account.
