Question about HTC G1

1 Answer

Not receiving all my calls

I purchased a g1 phone from t-mobile I have switched the phone 3 times with t-mobile and I have changed the sim card 3 times. I do not receive all my calls about 50 % of my calls go directly to voice mail my phone does not even ring. There must be something that can  correct this though I have been on the phone with t-mobile for at least 20 hrs. They could not resolve this problem. When I first called they instructed me to shut of the 3g service in the settings. I did receive calls with this fix but I paid for a 3G phone with 3g service. At this point T-mobile is sending a blackberry curve in its place. I would like to use this phone if I can get it up and running

    I have tried reseting and it did not work. I no longer have this phone I have a Blackberry Curve now. T-Mobile did a switch for me

    Same problem, I read that I should turn off autosync. Although now I am not notified of new emails until i go into gmail, press menu and press refresh. This isn't always the fastest, especially outside 3g networks.

Call up tmobile, do not tell them you have a rooted phone or that it was modified in anyway, otherwise they will blame it. They will be able to help you get it working by modifying / adding some settings in your phone.

How do i unlock my PUK lock


It seems you encode a wrong sim card password?

PUK means "personal unlocking key" .

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

You need to call your phone service company, they can retrieve the puk code from a database

for free.

In your case you need to contact your SIM card phone 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 should not ask for the PUK anymore.

Puk code for a t mobile g1

The puk code is sim card spesific it comes with the sim card when you get it or you can get it by calling your phone service provider of the sim card to get the puk code.
if you have entered the puk code wrong too many times you will make the sim card useless and you will have to contact your phone service provider for a new sim card, it will probably cost.
