Samsung diva phone locked and password forgotten

Try a hard reset: Enter *2767*3855#

You'll probably lose everything on your phone, if nothing was backed up to your SIM card.

You can hard rest your samsung S5620, but remember you will lose all your contact, messages, phone book etc.
- turn OFF the mobile - remove the sim card from the mobile. - turn ON the mobile and wait for the home screen to appear - now enter *2767*3855# wait for the phone to reboot. - Upgrade Monte firmware by downloading Samsung Kies and PC Sync.
Hope this helps,

My mobile asking mobile pin no. but i forget my no? what can i do? please help me

If you for got the pin number of your phone most probably it would lead to PUK lock if you attempt to put pin number at least 3 times.
So i would strongly suggest to call your service provide to unlock PUK, (they wil just give you a code to reset the pin) This will give you an option again to create a new security code or PIN.
Please refer below for some information:
  • PIN CodePersonal Identification Number), is the password for your simcard. You can choose to set the pin code request at each switch on of your mobile or whenever there is a change in simcard depending on your mobile functioning.
  • PUK Code is the code requested by your sim card whenever you have enter wrong password for more than three times. The PUK code can be only provided by your supplier.

Forgotten password AND puk number

To unlock your phone from forgotten password, follow the information from this link.

When you enter a wrong pin number three times the phone asks you for a PUK number. The PUK code is generally eight digit number This PUK number is an unlocking code which helps you to unlock the phone and use it. If you enter a wrong PUK number 10 times than you simcard gets rejected. Then you will have to buy a new simcard. It might happen that your phone might ask you for PUK2 after you enter your PUK number. You can find the PUK code is in your SIM card documentation Starter Pack. If you do not have this then contact your phone service provider. Your cell phone service provider can give you the PUK code once they have confirmed your identity to prevent any stolen SIM access.

Forgotten pass code

take out the simcard and power up the mobile and enter the following the phone will shutdown then reboot itself, that should remove you old password and reset it back to the default full reset *2767*3855#
That sets all settings back to factory settings.
