how to unlock g1 without foreign sim card? - G1 Q&A, Help & Troubleshooting

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.

I hope I am allowed to post this

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.

unlocking without a SIM card?!

Hi. I am wondering if anyone can tell me the procedure to unlock my AT&T Tilt without another carrier's SIM card?
I have the unlock code from AT&T, but I do not know the key strokes to bring up the dialogue to enter the unlock code. I do NOT have access to another carrier's SIM card. Can anyone help?
Thanks!

Why are you wanting to unlock it without the need for another sim? You can use the phone without a sim card in there so it's not like you have that restriction. Just keep the code on the phone and when you have the need, it's there for you whereever you are.
Or if you're wanting to unlock it to sell it, just include the code with the sale. The buyer is going to know it's an att phone, and as long as you have the code to unlock it, there's no difference. If anything, it makes the phone more "new" than if you turned it on the unlock it and then sell. So depending on how you pitch it, it could be an additional good trait
Borrow the other carrier SIM from your friends or go to T-mobile store to do the test.
I had old line with T-mobile. Did the unlock in 5 sec. After putting the T-mobile SIM it ask for SIM lock code...
you can goto a cell phone store. usually the people would let you use a foreign sim.
another idea would be to buy a tmobile to go phones. not that expensive. and you'd get a backup phone as well depending on which you choose. for example, the nokias are real easy to unlock for free
Thanks alot for your replies.
Actually, yes, it is to sell the phone. So, I assume what I will do is just include the unlock code with the sale. It would be nice if the phone actually had a series of keystrokes that you can enter to in order to bring up the unlock dialogue.

Unlocking the sim for AT&T

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

Unlock G1

Hi Everyone
Is it possible to unlock a G1 either rooted or unrooted without having to obtain a code from T-Mobile [I was quoted £15]?
There are people on eBay offering it as a service by sending them my IMEI number, are they doing this using an application which generates the unlock code based on the IMEI, if so then does anyone know where you can get the app to do this please?
I bought my G1 last month, unlocked for ATT. When you boot up the phone with a new SIM card, you put in ATT APN settings to use it with an ATT SIM card. When I installed Cyanogenmod, it automatically detected my SIM card, I'd try Cyanogenmod.

That is horrible information. It doesn't work that way.
But to answer the question either it's t-mobile or one of those people on ebay.
Its to easy bro, go threw T-Mobile via their chat tech support, tell`em you want the unlock code for your cell, theyll ask you for some info and in a few days theyll email you the info. I had this big story I was gonna tell them that I was going to Mexico on vacation and wanted to use my phone over there lol but they didnt ask me anything just the info they needed for the phone.
Goodluck

[Q] another question about unlocking

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.

[Q] C6906 "SIM Online Unlock PIN"

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!
