So I just left tmobile this morning and ported my number to straight talk (using an At&T micro sim card). I am having issues getting mms to work. I tried the APN settings from straight talks website but nothing worked (no data, no mms). I searched a bunch of forums and found an APN setting that gets me data, but no mms. Anyone else have the Tmobile Samsung Galaxy S3 (non LTE) that switched to Straight Talk At&t sim card and have everything working?
Thanks in advance.
