anyway, did you check settings>wireless>more>mobile networks>APN,and make sure straight talk box is checked? just an idea.
good luck

err on the side of kindness
yeah i have tried 4 different Straight Talk APNs and none of them fixed the problem, the crazy thing is, is the phone was working great till last monday after using it for a year and then bam it starts doing this, i thought that the sim card was maybe to old or just stopped working, so i bought a new one, and that still didnt fix it...
