Hi,

If you need the unlock code you can get it from the web site or mailing to [email protected].

You need to provide IMEI number in the site to get unlock code.


Thanks

try 8 zeros

you have entered the pin code wrong 3 times now you are required to enter a puk code to reset the pin code. 

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.

Try a hard reset *2767*3855#

IMEI has reported to barred,so contact Service provider to unlock the Code.

switch the phone on without a sim card,
type in *2767*2878# WAIT for it to reset,
once it boots up itself, the phone code is now gone,
if the phone is asking for a SIM LOCK password
then send it to someone who has the equipment to unlock it
