Straight talk phone has a Simple Mobile Sim card
I recently bought a straight talk galaxy s3 on ebay. It works fine except it will not receive or send mms. I can post pictures to facebook...but not send them to my friends via text.
I've tried factory reset, reprograming, all of that. I looked at the sim card that it came with and it is a Simple Mobile sim card. I have it on the straight talk network though. If I bought a new Straight Talk brand Sim card for it would it be possible it will fix it? I tried downloading the straight talk data app and it says I need a straight talk sim card.
