Easiest way for you to get the "deep programming" info for your phone would be to:
--Call Cricket Customer Support (*611) and ask them for your subsidy code. If they ask, tell them your phone is locked and it's asking for the code. OR, stop by your local Cricket OFFICIAL office and ask them for your "Secondary Sublot Code". If they ask why tell them you need it for a third-party data cable you bought online. Sorry for the deception, but smart Cricket employees might give you grief over why you should have the code.
--Enter six 1's (i.e., 1111111) and then from the right menu button choose "Service"
--On the next screen, choose "Programming". The phone will now ask you for your subsidy/secondary sublot code. Enter it.
--Copy those settings down (especially for data, WAP, DNS, etc.) and post them here.
Good hunting, and thanks!
