How do I unlock my tmobile g1 sim card PUK lock?

These directions are for an AT and T phone, but other than that, are the same for any carrier. A PUK (PIN Unlock Key) code is required to unlock SIM cards that have become locked following three successive incorrect PIN entries. If your SIM card becomes locked, you will need to get a PUK code from your phone carrier to unlock your SIM card. You can obtain your phone's PUK code from your carrier in one of these ways: Log in to Your account.online Use a Technical Support Chat Contact your carriers Customer Care Get Your Phone's PUK Code Online Go to the Phone/Device page. From the My Phone/Device screen, select the Unblock SIM Card link under the My Make & Model heading. The Unblock SIM screen will display your PUK code and will give you instructions for unblocking your SIM Card. Once you receive your PUK code, you will need to enter it into your phone to set a new PIN code. Note: If you enter the wrong PUK code 10 times in a row, your SIM card will be invalidated, and you will need to purchase a new SIM Card. The phone will display the following error: "PUK blocked call operator

request code from tmobile or htc

request from tmobile or htc

A request for a PUK code ("Personal Unlocking Key") will appear on your phone if your SIM card PIN code is entered 3 consecutive times incorrectly.

Your SIM card will then become "PUKed" or Blocked. This is a security measure to protect your service.

You need to call the Customer Service department of your cell phone provider and they will give you the PUK code which will unblock your SIM card.

call the carrier. only the carrier has puk. if not an option. buy new sim card

Contact your service provider and request your unique PUK code..

I had the same problem.. G1 phones are not really designed to deal with this issue very easily.
The only way around it is if you either:

a) remove your SIM card and put it in another T-Mobile phone, you can enter the code that way
or
b) take it in to a T-Mobile store and they will put it in one of their phones for you to enter code

The PUK code is a code associated with the SIM card and not with the phone.

You have only two ways to get rid of the PUK code. Either you replace the SIM card , or you call phone provider that issued the sim cadr (eg. At&T, Virgin, Tmobile , Vodafone, Telecom etc.)

PUK means "personal unlocking key" .

The PUK code is asked if you enter a wrong pin 3 times.

You need to call the phone company that released the SIM card, they can retrieve the PUK code from a database for free.

In your case you need to contact your SIM card provider technical support to unlock the SIM.


The PIN and PUK are related to the SIM card, not to the phone.

If you replace the SIM card with a different one, then the phone will not ask for the PUK anymore.eee
