I have had my Lumia 521 for about 2 months now. I still cannot get the MMS messaging to work. WIFI calling is off, so I know that's not an issues. I called T-Mobile multiple times, tried many different things, including setting up access point information. Nothing seems to work. It was suggested to me by T-Mobile store employee that MMS is not working on my phone because I have no data plan. Is that true? Does this phone require data plan in order for MMS to work? I didn't see that requirement anywhere.
Any advices? I really want to get the MMS for this phone.
