I also need help with this issue. I have UNLOCKED iPhone 3Gs from AT&T and I cannot get the data to work even after changing APN with Unlockit.co.nz
Few more thing I wanna mention. "Data Cellular Network" is hidden on my iPhone unless I put in T-Mobile Sim Card, then that function shows up. I tried to the sim swap method, but the setting didn't save after I exit the menu and swap the sim back to Net10
I hope this can be fixed because I don't want to pay $50 just for talk and text
