Iphone Version : 4S
Question Posted by : Armando Reza
From : Mexico
I had an ATT iphone 4S and bought the gpp sim unlocker, but the problem is that i can’t activate. I tell you my proceeding so then maybe you can see my problem . I took of the att chip while off, and (as the manual of my seller ) put the “Iusacell” sim without the gpp, when it asked to activate, i took of the sim tray and put the interposer of gpp with the iusacell sim, and it took me out of the activation setup, ok, it nows recognize my sim carrier on the screen, but when i make calls it says it has an ” invalid sim ” and then i cut off my signal bar.
Ok, and i have another carrier ” telcel ” and i make the same proceeding with the same gpp interposer but this one does not recognize the carrier name on the screen, it stays in no service ” and searching status, maybe the interposer could be programmed only with the iusacell sim carrier when i made the proceeding before than the telcel’s ?
Also when i turn off the iphone 4s and put the interposer gpp and the 3rd carrier sim card, and then turn on the iphone, in the iusacell sim, it does recognize the carrier name, and the telcel sim does not recognize it, makes the same problem as i told before .
