[UltraSIM] Mexican People using it, please read.
I am having trouble with my UltraSIMs and Telcel's prepaid SIM cards.
I know of 1 person that has them working together, but he hasn't answered back. Anyone else has the 2 working together? I keep getting "SIM failure" error followed by an "Invalid SIM" message in the status bar.
If you do have them working together (UltraSIM + prepaid Telcel SIM) please let me know which version of ultrasim, I know of 3:
Round IC at the top left corner
Square IC at the top left corner
Square IC at the top middle position.
Can it be the jailbreaking method?
Righ now I am trying wih the second one, and no luck, so far I've tried with 4 UltraSIMs and 4 Telcel prepaid SIMs and always I get the "SIM Failure" message. When I go into the about screen, the ICCID field is blank.
StealthSIMs work fine with an SIM in Mexico, I dont know about NextSIMs or HyperSIMs, can anyone confirm a successful installation with prepaid Telcel SIMs?
