I am unable to unlock my phone my buddy gave me the pin number to unlock my phone i tried to unlock but it says wrong pin.

the unlock default code is usually1234 or 0000. If none of these work then you may have to flash your phone, take it to your local cell phone dealer they can do this for you.

Default Pin & Security Codes for SIM cards

A number of networks still use a default pin on their SIM cards at the point of dispatch as a security precaution. If you lose or forget the PIN code it can be irritating.

Please note these PIN's will only work if you have NOT changed the default PIN. If you enter the PIN code incorrectly three times, a lock will be put onto the SIM card, and you need a PUK code to unlock it.

You can obtain your PUK by contacting your network service provider.

Default Network PIN Codes:

O2 = 0000/4321

Orange = 1111

Vodafone = 0000

Fresh = 1210

Virgin Mobile = 7890 / 1210

Vodafone = 0000

Talkmobile = 0000

3 = 0000

Accidently hit phone lock and can't unlock it -- default doesn't work 0000

Step 1
Turn on the phone.
  • Step 2 Try to dial any number, and it will tell you the phone is locked. Press "Unlock."
  • Step 3 Once you press "Unlock," you will be prompted to enter the lock code or your PIN number. If your phone is locked and you never entered a lock code, the default lock codes are typically either the last four digits of your phone number or "0000."
  • Step 4 Enter your code and press "OK." Your phone is now unlocked.

  • If this doesnt work, try maybe 1234... And if none of that works, your cell phone service provider will be able to change it for you, as long and you can prove your the phones owner......

    thank you and please rate this answer.. :)

    I 4got my phone lock code 4 my w810i can any body help me?

    What you have to do is take ur phone into your cell phone carrier. They can unlock the phone and reset the password to default then you can change it to what you want or leave it. Also have you tried 1234. That is another number often used for default codes.

    lindipsy, it seems that the phone is asking you for your SIM's pin number. it should be written on it somewhere.
    Usually 0000 or 1234 work, if there is no real SIM PIN number lock.
