how to unlock g1 without foreign sim card?

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.

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

Have you tried the app found in the market? (you need the original Sim card from where you got the phone and any other company's sim card
Try searching for "SGS unlock" in market place. It should be called the "Samsung Galaxy S Unlock Tool".
Simply Run the app after installing (while using the original Sim card) and it should give you two codes: an unlock code and an unfreeze code.
Once you get them, I suggest writing it down and/or emailing it to yourself.
After that, turn off your phone and swap the sim card to the one you want to use. The phone "should" ask you for the unlock code when you turn it back on and after it has booted. Simply enter the unlock code and you phone should then tell you it's unlocked (if everything works ok otherwise it will say it was unsuccessful).
Note: I am on Bell in Vancouver running the stock 2.1 firmware and it's worked fine for me. There have been people who were not so lucky and it did not work for them. There are even those who have gotten their phone locked due to trying to many time when after it fails to unlock, but that is what the unfreeze code is for. If you're with Orange mobility, I've read that some of their phones were already unlocked. You could always just try a different sim card and see if it accepts it if you haven't done so already.
Hope this helps.

Thanks for replying, new to this site not sure what I'm doing !
When i paid to have the phone unlocked i had already canceled my o2 monthly contract so the phone had no Sim in it when being unlocked, i don't have the o2 Sim anymore, i brought the phone from o2 so they might help me out I'll have to ask them. I've just put a o2 pay as you go Sim in the phone & it didn't ask for the Sim Network Unlock Pin but with the 3 contract Sim it does ask. I have installed the SGS Unlock tool but i haven't run the app. I'm having the phone unlocked again tomorrow so he hopefully can sort it out. Thanks again.

I tried to "SGS unlock tool" and nothing does not give me the codes. When I go to the root gene codes told me: "Sorry, no codes found. File not found: Do you have S Business"
I have no idea what to do.
Is there some other way to decode or knows someone why this is happening?
I also tried with Generate Unlock Windows, error is: can not find nv_data.bin

[Q] Activating the HD7

Hi all
This is hopefully the last factor in deciding whether I will get the HD7 or not.
I read on cellhub that you have to "Activate on Delivery". What does this mean? Can you not use the phone before it is activated or does it only need to be activated on T-Mobile if you are using it on T-Mobile?
Thanks again.

not sure what that is, mine arrived, poped in the sim, had touns of trouble with importing contacts, but once I got past that, the phone works just fine out of the box.
Im Tmobile USA.
now using the empty OS it self is a whole other issue

If you mean an iPhone like iTunes dependent activation there is none. Just pop the sim in and you are ready to go. In fact, I didn't even entered a SIM when I first opened it

Ok, great, thanks very much.
Were you two both on contracts or prepaid?
I will be purchasing the phone and then using it in South Africa so I don't want it to get here only to find out that it has to be activated with a T-Mobile sim card

You mean unlocked/locked phone. If you bought yourself an unlocked phone there shouldn't be any problem with your SIM . Just as I did

No, I know I'll need to unlock it.
I want to know if the actual phone has to be activated by T-Mobile before it can be used.

Do I require cables, software or any technical knowledge?
Unlocking your HTC phone by HTCimeiUnlock.com is very simple. You don't need any cables, software or technical knowledge. All you have to do in order to unlock your phone is to switch it on with a not allowed SIM card and simply use your phone's keypad to enter the eight digit unlock code provided by us!

Looks like no.

[Q] Official operator unlock code not working - ideas?

Last year, I got an HTC Incredible S and absolutely love the phone. The only thing I did not like was the capacity, so I got a 32GB card instead. I do not know if there is a special procedure to follow when you change the SD card, so I just copied everything from one card to the other. Of course, some programs did not find the data, so that data had to get loaded again.
The phone was locked to an operator in Norway - Telenor, but as I used a SIM from an operator that used their network, I did not need to switch. This year I needed to go back to Brazil and wanted to make sure I could use my phone with my TIM number here. So I called Telenor when it was getting close and got the unlock code. I then tried to unlock it after changing to a SIM from a different network in Norway. But it did not work.
After trying a third SIM card, it seemed to work, so I thought it was ok and the phone had never actually been locked. How wrong was I...
After arriving in Brazil last week and picking up my SIM from TIM Brazil, I found out that the lock is very much in place. And the code I got is not working.
If I was in Norway still, I could send it to Telenor for free and they would fix it, but I am not. So what can I do to unlock it?
The full model as displayed by the phone:
HTC Incredible S S710e
The instructions for unlocking never mentioned anything about keeping the original SD card, but can that be the reason for it not working?
After I changed to the new SD card, the cold boot of the phone is extremely long, but most of the day-to-day operations is ok.
Any suggestions to what I can do to remove the operator lock? I have noticed that there is an official site from HTC where you can unlock some things of the Incredible S. Will that do the job?
I really need to be able to use my phone here. I hope someone out there have an idea what to do.

No the unlock procedure at HTCDEv.com is to unlock the bootloader so you can root and customize your phone. Unfortunately, rooting your phone will not help ou SIM unlock your phone.
You need to SIM unlock your phone which the unlock code should have done. Also the SiM unlock code has nothing to do with your SD card.
You need to contact Telenor and tell them that the unlock code does not work. Or you can try one of the paid services that provide unlock codes for a fee.
