My provider is straight talk. I live in the USA. well actually it was hit and miss depending on the signal strength. I got the sim card when I went with byop with straight talk, it's been a few weeks now'
Actually here is what happened I seen a (what I thought wwas a phone number on what sim number} well I changed that to myphone number. I know really dumb. Anyway I started to get this alert thing a red triangle,well when I click on the tab thing on the left,It said info about alert it said error 313, I have went back to factory settings no good, turned it off then on ,no good, then I took the battery and sim card ot then replaced them still no good. I have know idea what the original number was ,so I tried putting my sim card number in it still no good. I don't think its that serious,I;m just not that smart on this. No I can't recieve text either. I hope someone can help me.
