I have a Nokia Lumia 822 and wanted to go cheap, since supposedly the 822 is unlocked i bought a straight talk tmobile sim card and $45 unlimited card for it. I got it to make calls but the APN codes straight talk gave me for the data doesnt work. I called them but they did not know since windows 8 is new. PLEASE if someone knows the solution to my problem plz help. If not then i just wasted $60
