I want to change phone lock code on T280i i have forgotten original code. i dont want to change sim lock code only phone lock


HI If you are asking for pin contact your service provider ,
he will give you a default pin .
If you try pin more than few predefined no of times your phone will ask PUK
code which can also be given only by your service provider which is specific for each and
every mobile number . Do not try PUK(new pin code) code many times or else your sim will be
blocked and you will need a new sim.
Contact your sim customer care department over phone. Its free of cost to get the pin or puk no.
Go to the nearest service outlet of your service provider they can also help you.
There is no other go than the above procedure only your service provider can give it nobody else
in this world nor any software.

Hope this helpout......

I forgottem my phone lock code,how can i inter in to my mobile?


Was the phone locked? Or the SIM card?
Because if the SIM card was locked then type in 3 times a wrong pin, then they'll ask you for a PUK code, call your service provider and ask them for your PUK code.
If the phone was locked- in other words, you put a pin to prevent people from using your phone by changing SIM cards- then I'm sorry I can't help you.

Forget the phone lock code


If you need the SIM Pin number to switch the phone on, then you have to enter any Pin number 4/5 times, then the phone will request a PUK number. This number was on the plastic card that your SIM card was attached to. If you don't have it, only your Network Service Provider can supply it to you.

If it's the Security code you need, to get into certain settings IE. erasing received calls, missed calls, timers etc... the Nokia default is 12345 if you didn't change it, but if you did change it and you've forgotten it, let me know, I'll tell you how to retrieve it.
