Now I do occasionally experience the " no sim" MSG but it's usually if I run into a dead zone, am underground, etc. I just switch to airport mode and switch back instead of resetting the phone. Also try internet2.voicestream.com as ur apn. With tmobile you have to talk to a rep from "tier 3" LOL good luck
if you're using ultrasnow you dont nee da turbo sim, your "no sim" problem is probably caused by the turbosim.. and totally different from the OP.
