[How To] Activate G1 Without a T-Mobile SIM card

[Cody Overcash]

Unlocking and activating the G1 is very simple. To unlock all you have to do is purchase an unlock code for your G1, insert your sim card and enter in the code. Activating on the other hand is a bit more of a problem.

I have read on many sites that the only way to activate is to have a valid T-mobile sim card and use that to activate. This is wrong. There is a much simpler way to activate the G1 with any sim card of your choosing after you have unlocked the phone.

The rest of this post will guide you on how to free and activate your Android phone from the T-mobile network in about 5 minutes (assuming you already have the unlock code). Sorry for the low-res pics I didn't have nice camera on me at the time.

Step 1

Purchase the unlock code for your G1. EDIT: We now offer T-Mobile G1 Unlocks, you can purchase them for $25.

Step 2

Put your carrier's sim in the phone. I'm using an AT&T sim.



Step 3

Turn on your phone. It will ask you for the unlock code. Simply type in the unlock code you got in step one using the keypad.



Step 4

The phone will tell you to touch the Andriod after which you need to setp up a new gmail account or sign in with an existing gmail account. This is the activation process and it will of course fail since we aren't using a tmobile sim in our G1. Move on to step 5



Step 5

After my activation failed I pressed try again which took me back to the screen where I needed to enter in my gmail account and password. This time instead of providing the information press the Menu button on the phone. A nice little pop up will appear for APN Settings. Select it.



Step 6

Now you have a list of carrier APNs showing and they are all T-mobile. Select one and you will see all the Settings for that APN. From here you can either press menu to add a new APN or edit the settings for the existing one you are viewing. I chose to edit the existing one since I wont need it.




Here is the trick. You need to enter in your carriers APN Settings when you create a new APN or edit an existing one. I am using AT&T so my settings are as follows:

Name: AT&T
APN: wap.cingular
Proxy: leave blank
Port: leave blank
Username:WAP@CINGULARGPRS.COM
Password:CINGULAR1
Server: leave blank
MMSC: http://mmsc.cingular.com
MMS Proxy: wireless.cingular.com
MMS Port: 80
MCC:310
MNC:410
APN Type: leave blank

If you don't know your carrier's we have built a large list of carrier APNs so you can give it a shot. Are we missing an APN or have an incorrect APN? Simply sign into the site and you can edit the list to help others out. If that doesn't work you may need to call your carrier and ask them for the APN settings.

Step 7

You have now entered in your carrier APN settings so hit the Menu button and select Save.

Step 8

Press the back button on your phone until you get back to the sign in or create gmail account. Follow the steps. This time assuming you have entered in the correct APN settings for your carrier instead of the "There is a problem communicating with the Google servers" error you will get a nice signed in screen.

Congrats! Your Andriod phone is now unlocked and activated running on the network of your choice. You should be able to use all the phone's features and be totally good to go!

Cash-

Do you have an iPhone data plan activated on that SIM card? Or do you have a different kind of data plan activated?

Thanks!

AT&T 3G doesnt work on G1. The 3G frequencies used by T-Mo and AT&T are different.

Am Rami from Saudi Arabia. I just recieved my G1 from e-bay. it was unlocked by the seller.

I added the APN settings for my provider (STC, Saudi Arabia) but still I can't get passed the google activation! Why can't I just do this on wireless....any ideas?

Does it even work in Saudi Arabia. I remember I checked our network with the G1 specs, and they fit. Did I miss something??

u need to have a data plan with your carrier.

[bianconeri4ever]

I do have a data plan. That same SIM cards works perfectly on the iPhone. Do MCC and MNC values matter?

Oh btw the 3G logo does not appear on my G1, it should fall back to edge/gprs right? I see in the screenshots no 3G logo either...

Yes, MCC and MNC values are important.

Well I used 420 001 (thats what google tells me). Had to add an extra 0 since the android only accepts 3 digits for the MNC value...

Still is not working....what am I doing wrong?

The ebay vendor gave me numbers to insert http://www.isramart.com/codes.htm am assuming these are the numbers that are provided by http://www.unlock-tmobileg1.com/ right??
