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 bought a g1 that is not unlocked, and I wondered if I have to have a tmobile sim card to unlock it.
No, the opposite, you need a sim card from another provider (along with the unlock code) to unlock it.

In The U.S., i saw you were not, you get the code from T-mobile unlike most other U.S. carriers they give it to you. Then any sim card other than an active T-mobile, even old non-active ones I have used as it just needs something to look against to enter the code. Here is the instructions....
T-Mobile Sim Unlock Request
Sim Unlock Reference: nnnnnnnn
IMEI: nnnnnnnnnnnnnnnn
Unlock Code: nnnnnnnnnnnnnn
Thank you for taking the time to contact T-Mobile. Below you will see the Instructions for unlocking your HTC device.
1. Insert the foreign SIM card
2. Power on the device and the display should read "Please input unlock code"
3. Enter the unlock code and the device should display "Phone is unlocked."
4. Allow the phone to scan the network (or manually click on the antenna icon to do this)
It is very important that the instructions and SIM unlock code are entered correctly as listed. If you receive an error message while performing the instructions do not make any further attempts to unlock the handset. Please be aware that if an excessive amount of incorrect attempts are made, the phone will be permanently locked. You will need to verify the IMEI by pressing *#06# and contact Customer Care for support.
Thank You,

...I forget the time you need to be with them as I have for years....
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 was on Sprint recently, and upon entering my account I saw this option "Get my PIN1/PUK1 unlock code". What exactly is this and where would I use this at on the phone. Also are there and advantages or disadvantages to no having my PIN1/PUK1 unlocked.

it's if you happen to lock your sim card on accident you would need the PUK code to unlock the sim in order to be used again. I work for AT&T and I get this call on a regular basis.

Since I would apparently want to avoid doing this, how would one lock the SIM card inadvertently? I'm going overseas soon, and wouldn't want to mess up my foreign SIM card. :fingers-crossed:
I purchased a used Incredible S and when I purchased an unlock code online I was able to network unlock the phone. 2 days later it failed to read my simcard anymore, did it lock back up? It doesn't give me the option to enter an unlock pin like the first time I unlocked it, so how can I check if the phone is still unlocked? or how can I input my unlock code again if it needs it again? HELP
Also, the sim card still works fine in my old phone so it isnt the sim.
