Unlocking G1

[fjnty5]

Hi i am new to these fourms, i bought a g1 and got it activated, im using it without the t-mobile G1 Data plan and its just fine, i was curious, if i was to unlock the phone do i have to go through the google sign-in setup process again; like the part it prompts me to log into google server with my email to gain access to the phone it self?

No i don't think you would have to do the sign-up process again but you said your using it without a data plan and i thought some of the features don't work unless you have the data plan.

Hello and Welcome to the Community.

I found this, it may help you out...


"I got my G1 officially unlocked from TMO for free within a day or so. Process was call 611 and ask for a SIM unlock. You will need the phones IMEI (from the dialer enter #*06# and confirm your account info.

Criteria to get it is having the T-Mobile account the G1 is on to have been active for 90 days or more - NOTE the G1 does not have to have been on the network 90 days, just the account the G1 was added to! So if you upgraded or added the G1 as another phone your account length for the previous phone(s) is taken into account.

Turnaround was about a day and a half, you will get an email from an automated system (email from is ARSystem Notify) with the title "T-Mobile Sim Unlock Notification"

NOTE: To unlock the phone you *WILL* need a non T-Mobile SIM card as inserting that in the phone will prompt for the unlock code after power on. A dead AT&T/Cingular or other network SIM can be used for that. There is no expiration on the unlock code - just ensure if the code doesn't work NOT to keep attempting as the phone will be permanently locked to T-Mobile with 3 failed attempts. [Failed unlock code means you provided the wrong IMEI number to TMO cust care]

An unlocked G1 will work on any GSM network or any UMTS2100 network (3G) using a local network sim card. It will NOT work on AT&T for 3G nor will it work nationwide on the Australian 3G carriers using UMTS850. So basically it will work anywhere in Asia, Europe, etc on UMTS2100 networks."
