I changed my security code and i forgot my security code for nokia 6500 slide. what can i do to unlock it? reply asap please.

Hi, you can unlock it from www.wickedunlock., com www.unlocking4u.com or www.theunlockarena.com very quickly and easily
Note: unlocking is not free, You will be charged to get your unlock code. The only way by which you can get the unlock code for free is by calling your service provider and requesting for your unlock code.(you can use any of your friend's phone to make this call) If your service provider refuses to give it to you, then there is no other place where you can get a free unlock code.
But if you really want it for free, you can try master reset but your files will be lost dear if you haven't backed it up..contact your current service provider to get the master reset code..
OR try these steps for full formatting:
Switch-off your phone.
1. Press and hold 3 keys; Green dial key, * Star key, no. 3 key on keypad and then press the power on/off to swtich on the phone.
Remember, do not let go the 3 press and hold keys until you see a formatting word screen show!

2. After a few minutes when the Full phone formatting completed, your phone will back to original system and factory settting.
(your imei number is needed dear) GoodLuck=)
