So wondering if its true to call in to do a sim unlock with tmobile then after flashing a rom would this be a permanent unlock for oother service providers or no? thoughts anyone??
Phones are SIM LOCKED to one specific carrier. Once you SIM unlock it, you can pop in any other carrier SIM card and it will work.
As far as permanent, from my understanding you should be able to flash your phone as much as you want, and it will remain SIM unlocked, but I've never done it personally, so I don't know.
Hello everyone,
I'm trying to find out how to SIM unlock my G1 without having an AT&T sim card. I have an unregistered T-Mobile sim card available if it could be used at all.
I tried searching but I must be using the wrong search terms because I keep getting results about unlocking using an AT&T sim card to get the request for unlock code to show up.
I have the unlock code, just need to be able to enter it.
dunno if its the same as the UK but I unlocked mine the other day from T-Mobile with an unlock code and all i had to do was to put the wrong sim card in there (i.e. the one u want to use) and then it should prompt you for an unlock code....
Yup, just shove in the ATT SIM card and it will ask for your code...
I am traveling in Europe with my lg g2 and bought a Vodafone Sim card. When I put the card in it asks me to put in the PIN which I do and then it tells me that the Sim unlock operation failed.
I have tried both the pin and the super pin and neither work.
I am on AICP 9.0 nightly. I am going to try to flash the stock ROM that I found to see if that helps.
What can I do to use the Sim card?
Hi after unlock bootloader via toolbox i got no sim card detected even after restore factory rom
What could be the reason for that? also its look like i flashed dual SIM ROM on single sim UK version device and its looks working ok
have you find a solution?
No sim card mostly results from flashing the wrong region firmware.
I got a locked Tmobile h872 that I put TWRP and flashed diferent roms so I get rid of the Tmobile Lock thing.
Suddenly it just wont read my sim card anymore. Ive tried reset, change sim, flash other rom, kernel...nothing.
It just doesnt reads the sim card ! Any idea? Its been working for few weeks and just stoped. I wonder if thats a hardware issue not software.
