These are the codes for Network 23430000 T-Mobile-One 2 One;United Kingdom. IMEI 355506016220177 To enter the code to the phone (switch on without SIM card).
Input the Code in the phone as follows:


Here: ?????????????? You should enter generated code.

First code in the end of the string must be added + 1#
Code number 7 in the end of the string must be added + 7#

If you have proper software and You know on which lock, phone
is closed just simply enter proper CODE.

If YOU DONT KNOW – which lock is closed do the following:

1. Enter the first code, if it’s the wrong code – WAIT 30 seconds!!! And then:
2. Enter the code number seven this will open all locks.

How to get ‘p’ ‘w’ ‘+’ signs?
* several times on keyboard of phone...
Your code's are:


Now a message should appear something like “Sim restriction off”. That means your phone is now unlocked.

If the codes don’t work after entering 5 codes You will lock the ‘CODE UNLOCK FUNCTION’ and it will be possible to unlock the phone only by using a cable/device.

    The codes I GAVE you are for IMEI 355506016220177 and for Network 23430000 T-Mobile-One 2 One;United Kingdom.

    If they don't work it's usually due to the phone having been updated (Software/Firmware) or it's blacklisted:


    This is not a security code, but it works like one! To help combat mobile phone thefts, the networks share a database of the IMEI (International Mobile Equipment Identity) of mobile phones that have been reported stolen. Once a phone is on this list, it will not be allowed to use any of the networks.

    This can be a risk if you buy a second-hand phone, because if it has been stolen, or if an unscrupulous seller makes an insurance claim after selling, the phone you bought in good faith may be permanently disabled.

    Be very careful to check the source of a second-hand phone!

    If you can't unlock the phone by using the codes then it can only be unlocked by being connected to a PC using a Nokia 'Box'.

    Either way I offer my services free of any charge.

    If you have paid for the advice, I would like to know who you paid, and via which pay option.

    The unlocking devices for phones cost anything between £300 to £1000 + There must be a repair shop somewhere near you. If the IMEI shows that the phone is under a current contract, the IMEI would have to be changed. Once again it can only be done by connecting the phone to a PC.

N73 back camera auto on

My dear:
This error usually occurs when you attempt to use a SIM card from a network other than the network from which the phone originated (e.g. your Nokia mobile phone originated from Orange UK and displays the 'Sim Card Not Valid' error when you attempt to use a T-Mobile UK SIM card). The 'Sim Card Not Valid' error usually means the phone has been restricted for use on one specific network and you would need to unlock the phone before alternative network SIM cards can be used.

could You test the new SIM on another phone? Could be the housing of SIM damage on phone - hardware problem - Nokia Service.

in any case you need to find out which network and ask them for the unlock code.

Only the original network to which it is locked can provide this code.

Security code for LG KP100 (t-mobiles)

i have a lg kp100, I already bought a code to unlock it, but i don't know how to insert it. the phone is locked to movistar(spain) and probably the sim has not a network anymore. I am in greece now so I tried with greek sim cards but still nothing.

when I put the spanish sim it shows me "error de tarjeta sim" wich means error with the sim card, but there is nowhere option to access to security mode to insert the unlock code.
if there is anyone who can help me please contact with me
