The PIN (personal identification number) or PUK (personal unblocking key) are security features provided by your network service.

The PIN and PUK are provided on your SIM package, and can be changed many times. The basic purpose of these codes is to provide a security.These codes are normally used to prevent your SIM card from unauthorized use.

You can get this type of security by enabling the PIN check option in your mobile phone. If this feature is enabled, the phone requires your PIN each time it is switched on.There may be different solutions for your problem.

If you have not changed the original PIN of your SIM then you can get easily this code from the package that has come with your SIM card. Get these codes from SIM package and unlock your mobile phone.But if you have changed your PIN and now have forgotten it then there is also a way to resolve it. When you give an incorrect PIN three times to your mobile phone it will block your SIM card, then in this case you have to provide a PUK given to you by network provider. And you can get your PUK any time by calling at the help line number of your network service center.

It's showing simcard rejected


Hi there,

If your sim card is rejected please re-insert it, it may be due to loose the way you inserted it.
If it shows rejected after re-inserting,it is better to replace your sim card or you can contact Sim-care company or your phone provider.


Hope it helps.

Thank you for using fixya.

Default security code?


Hello keith g670,
his will also bring the phone to default settings
1. First do a CUSTOM reset: *2767*2878# (star 2767 star 2878 hash)
turn off the phone

2. take out the battery and sim and put non-network SIM and insert it half way only,
so it won't ask for network password and when it shows "Insert SIM" message.
Only then fully insert the sim without removing battery or turning it off (tip: use a pin to push the sim in)

Now put the battery ,and switch the phone on .(phone shows "Insert SIM" message.)

3.With out turn off the phone push the sim fully in. At this stage the phone is still asking to "Insert SIM"

4. Make a FULL reset by typing: *2767*3855#(star 2767 star 3855 hash)

5. The phone should reboot working with "wrong" sim inside.

6. Make a Change the NCK password to 8 zeros by typing: *7465625*638*00000000*00000000#(star 7465625 star 638 star 8zeros star 8zeros hash)

7. Now Disable network lock By typing: #7465625*638*00000000#(hash 7465625 star 638 star 8zeros hash)
Phone is unlocked (check with *#7465625#)

Tried and tested OK
