This is the 2nd time this has happened to me I was orginally using a turbo sim card with Tmobile and it was working ok sometimes I wouldnt get calls but very rarely. But I went with the Yellow Sn0w unlock it worked fine at first but after a day or 2 it just stopped working and it says no service. I rebooted the phone and took out the sim card it gives me the 5 dots and it searches and it says no service does anyone know what Iam doing wrong?
