That means the phone is locked in a carrier other than your SIM.

Hi,

problem can be solved.When you buy a new Sim card or a new phone from a different country, it show unregistered Sim.That means the Sim or the phone can work in your own country.

You will needs to contact the service provider of the phone or Sim card you are using to enable you use the Sim or phone in your country.

Take care.

Look at the power supply, look for burnt parts, bad capacitors, etc.

if not you will need to flash the card so that it works with this phone.

take out the sim and insert it again or reinstall the phone software.

first you have to press the menu button then immediatly press star symbol button. or soft one key press first then it shows in disply screen which is the unlock button, you have press that.

This problem is due to your phone's sim card IC malfunctioning. It may get damaged due to phone dropping gently into rough surface and its crystal structure may break due to it. for any queries mail to [email protected]

well... seem like you phone has got locked from the network may be accidently in case of stolen better check you service provider and if they say every thing is fine try to flash your mobile .it has some perticular number to flash it try these number *#7780# (password 12345)
