I know some older phones won't function without a qualified SIM placed into the phone. Do I need a SIM card to unlock the 8125? I only have a T-mobile SIM and no Cingular SIM.
Hi - I bought a G900F off ebay which is apparently sim locked to the EE network. My sim card is Tesco Mobile (great deal).
From what I have read, rooting/flashing custom Rom will not unlock the network sim lock.
Is my only option to have EE unlock the phone? Any recomendations for websites which are trustworthy and include the EE network?
Does it matter if the person I bought the phone off did not use the phone before? Would this mean it has a region lock?
This is all very boring, my GS3 was so easy to get working.
Thanks,
RG
It doesn't matter what the status of your phone is or what network it is servicing. You will just need to input the unlock code numbers on the keypad. You have to pay a fee of course.
Thanks in advance for your time.
I consider myself somewhat savvy. I have searched all over for an answer before asking:
I bought a SM-G870A and I have tried putting an H2O SIM card with no unlock screen. I tried two other SIMS with no unlock screen. I assumed it was unlocked.
I tried selling this phone to a guy who was going to use it in Mexico and told him it was not SIM locked. He tells me that when he puts his SIM card in it asks for an unlock code.
I am lost as to why it would suddenly ask him for an unlock code but all my SIMS did not. I have not been able to see him try in person yet.
Why would I be able to put SIMS in the phone and not get asked for an unlock code. I thought that meant it was unlocked?
Thanks for the help!
I just went through this "sorta" thing when I unlocked my t-mobile s5. I took out my t-mobile sim and put in a metropcs pcs sim and got no unlock screen upon reboot. I put in a cricket wireless sim and upon reboot I got the unlock screen, which I quickly put in my unlock code.
I'm assuming since metropcs is owned by t-mobile, that is why it didn't ask for an unlock code.
Is h20 owned by at&t, if so, that could be why the phone didn't ask for an unlock code when you put in the h20 sim

Thanks for the feedback. There could be something like that going on.
h20 uses the ATT network.
I tried a Simple Mobile (T-mobile) and no unlock code prompt
I tried a US Cellular LTE card -- would not connect to network -- no unlock code prompt
I tried a Verizon LTE card -- Same as US Cellular
I am stumped as to why this would happen. I would think a locked phone would not accept those cards without an unlock code prompt.
Hey guys just purchased a code from cellunlocker.net and was wondering can I still unlock the phone if I don't have a foreign sim card? Just switched to Verizon so I no longer have service in the ATT sim. Is there a way to manually bring up the screen where you input the code?
Is there a way to check if my phone is carrier locked without having another sim to test it?
