Hello! I have an unlocked C6906. Recently, after putting in an AT&T SIM from another phone, the C6906 has started asking for a SIM network unlock PIN. However, the phone is factory unlocked, having been bought from Omega Cell fully unlocked. It has worked on AT&T in the past. In order to test if it's the AT&T SIM, I was able to go into an AT&T store, and verify that it is the phone and not the carrier. Additionally, I was able to take the SIM cards I was testing and successfully insert them (and use them) on other devices.
In order to further test, I bought and inserted a READY SIM pay-as-you-go SIM card. Same result occurs; SIM Online Unlock PIN. No unlock code that I can find seems to unlock it.
Help me, XDA community. I've searched the web high and low, I've flashed all stock firmware, I've done everything short of buying a new phone. I'm at wit's end.
Help!

I recently called up at&t and told them I was going over seas and i had an extra sim ( I dont really have an extra one ) and they proceeded to give me a code which to unlock the other sim. My question is am I able to unlock my current at&t sim with that code, and if so how can I do that?
Thanks

If you want your phone to work on any carrier network and to be able to use prepaid SIM cards just borrow from a friend a non att SIM card (like T-mobile).
Power down your phone; insert the "alien" SIM card; power up.
The phone will request you to enter the unlock code. Enter it. Remember that you have only 5 attempts otherwise the phone will be permanently locked to ATT and there is no EASY way to unlock it.
When finished, swap the cards and you are done.
thanks alot man, i just did that and it seemed to work. i just put my original sim back in, is there any way to verify that my phone is unlocked?
lol, put that other non-AT&T sim back in
I just received unlock instructions from tmobile, including the unlock code. The first step, howwver, is to insert a foreign sim card. I haven't left the country yet so I don't have one. Is there a way to proceed without a foreign sim card? I had a brand new sim card lying around and I tried using that, but after reboot it never asked me for the unlock code it just booted up into the home screen and asked me to sign into gmail. Any suggestions?
In wich carrier is the phone locked now? Tmo? If is on Tmo, and the sim isnt from Tmo, then your phone is already unlocked...if the sim is from the same carrier than your phone, then you need another carrier sim to unlock it...
He wants to unlock his phone without a foreign sim card. When you unlock, to be able to see the Unlock Code input screen a different sim card than your carriers must be in the phone. He wants to unlock without the second sim card.

You are perfectly allowed to post that, however that is not what he is looking for at all.
Just find a friend with AT&T and borrow their SIM card for the 5 minutes it takes to unlock the phone.
Dang, I used to work for T-Mobile in the PDA dept and never realized this limitation. I don't *know* anyone who has an AT&T phone and am selling my G1, need to be able to get it unlocked. Everyone I know uses either T-Mobile, Verizon or Sprint. I would hate to have to send the buyer the unlock code and have them do it themselves. Almost any other phone has a # code to type in, why not the G1?
Looks like it's not a G1 thing but a T-mobile thing. I had to use another non T-mobile SIM to unlock my HD7 as I am selling it.

The best thing you can do is see if any of your friend has a different carrier sim (IE: AT&T, Verizon, Sprint) and put it in. After you turn on the phone, it will then come up with the box that prompt you to put in your unlock code.
I have a UK SIM card coming in a couple of days, and I have received my unlock code from TMO. I will not be traveling to the UK until September, but want to test the unlock code now just in case TMO messed it up. is there any downside to inserting the UK SIM card in the G1 in the US just for unlocking purposes?
For more input, my phone is rooted, running DWANG 1.6 ROM. I intend to do a full nandroid backup prior to testing, and will also delete quite a few of my apps prior to traveling since I don't want to have lots of data usage when I am overseas. When I get back home I will restore from my backup. Anybody see any flaws with this plan?
Thanks.
I am trying to unlock my AT&T Samsung Captivate and I have followed the instructions in the reference thread for unlock/unfreeze for all SGS models. I tried both methods with SGS Unlock and ADB, as they both are supposed to do the same thing and as a result I got the same unlock and unfreeze pins.
After I got the unlock code I restarted my phone with a Fido Sim card but my phone doesn't ask me for a Sim network unlock pin and it just loads the desktop. My Sim card works in my other phones, so it can't be something wrong with my Sim. I also borrowed my sister's Fido Sim and still my phone does not ask for the unlock pin on start up and displays the there is no sim card in phone screen.
I'm hoping its not something wrong with the phone's Sim slot.
Does the Fido sim work in your phone?
It is possible that Fido is an authorized sim in addition to the AT&T sim.
Hello,
I have the same problem with my mobile. It is a toshiba TG01. Did you solve you problem?
Kinds Regards
I received an unlock code for my hd7 from t mobile and instructions say insert foreign SIM card, my question is what do they mean by foreign? I've tried an inactive t mobile SIM but it doesn't work.
lol well in the wildest sense of the word, try a sim card from another country lol
but i think even using an att sim would do (for your unlocking purpose)
also: if you asked for the unlock code and got it, the whole point is that you can go abroad and still use the same phone
if you want to flash to another rom, then just ask a friend for a non-tmo sim to proceed with unlocking
I am planning on using the phone while on vacation abroad I just thought that it would be better to get it unlocked before.
Hey guys,
I really messed up
So I received a Samsung Note 5 SM-N920W8 directly from Samsung. I need to use a Rogers SIM card in it. Not know if the device was locked or not, I thought I would try a non-Rogers SIM in it... I put in a Virgin mobile SIM and it worked. I thought to myself "GREAT, this is factory unlocked, WOO!" Until a few days later when I put in the Rogers SIM that I need to use in the device, and it asked for an unlock code.
Tried buy a code online for both Rogers and Virgin, no luck. Of course not, since the phone never went through carrier fulfilment
For work reasons, I need to use the Rogers SIM in the phone. Both of which are provided by work.
I never realized the phone would lock itself... I thought this was something only Apple did, where they ship the device unlocked, and it locks to the first carrier SIM inserted. I did not know Samsung did the same thing! Was I wrong in thinking this?
How can I get this unlocked? I'm trying to avoid rooting, as it would trip Knox.
There's no such a thing like sim lock option on any Samsung devices
I'm the biggest Samsung fan
Once you buying sim free device from Samsung it's always be sim free
I thinking you must be doing something wrong with settings
Nope, it's asking for SIM unlock code lol
What to do?
How did you receive a phone 'directly from Samsung'? That option doesn't exist in Canada - but in any event, your phone appears to be locked to Bell/Virgin. Phones don't lock themselves based on the SIM you put in. And why don't you ask whoever you acquired the phone from? If you acquired it legally, this shouldn't be an issue; if you didn't, you shouldn't be here asking for help.
