Hi,

NETWORK UNLOCK CODE:
To unlock your mobile you need to get network unlock code(NUC) from current service provider via phone or go to service provider office.

While you get the Network unlock code ,the service provider customer care officer will ask for your personal details to check whether the mobile belongs to you only.If they are satisfied with your answers they will provide with the network unlock code.

RESTRICTION CODE:

To get restriction code you have to call your previous service provider. This code is provided to prevent in case of theft taken place the other person cannot use your phone in other networks.

While you get the restriction code ,the previous service provider customer care officer will ask for your personal details to check whether the mobile belongs to you only.If they are satisfied with your answers they will provide with the restriction code.

Thanx

Insert sim


What is your problem with your Sim card? Is your phone shows the "No Sim" or "Insert Sim" or "Sim Rejected" or "Invalid Sim" error? If it is so i am here to help you. If your Samsung shows the "No Sim" or "Insert Sim" error then remove your Sim from your mobile and place it again correctly. If your mobile shows the error message "Invalid Sim" or "Sim Rejected" the your phone is locked to a particular network. To fix this problem you need to unlock it. Use unlock code to unlock your Samsung B5310. To get the code you have to submit network provider, country and IMEI number of the mobile. Make sure yourself whether you have knew the network provider to which your mobile is locked, country to which the locked network belongs to and IMEI number of your mobile. If not you can find the IMEI number in two ways:
1)Go to Options>status
2)Find IMEI on the back of your mobile, behind the battery.
3)Type *#06# and press call button. It will display your IMEI number.
You can find the network provider to which your mobile is currently locked by switch off your mobile and switch on it again. A logo of the locked network will get displayed on your mobile screen. After knew all these get the code from the site Theunlockarena.com ,by submitting these to them. Unlock it yourself using unlocking instructions which is given in the site itself.

My Samsung Mobile model is Gt-E1085T.I have use Phone lock system.After I unlock my mobile i forget my Phone lock password.So now i can not lock my mobile With Security code.Please give me suggestion.


How To Unlock a Samsung Phone1. Power on your Samsung mobile phone with the UNACCEPTED SIM card inserted.
2. Your Samsung phone will prompt for a password (unlock code).
3. Now enter your Samsung unlock code.
Otherwise, if your Samsung mobile phone displays "Insert Correct SIM Card" then:
1. Turn on your Samsung phone with an UNACCEPTED SIM card inserted.
2 - Type: #0111*CODE# (Where CODE is your Samsung unlock code
Once you have unlocked your Samsung phone you will be able to use it with any phone carrier or network. Most websites would suggest paying for high priced unlock codes and instructions. Always try calling your phone carrier before resorting to paying for an unlock code. If this phone guide did not help unlock your Samsung phone, please let me know.

Phone locked


Okay, well i do not know much about these phones but i will give you a few options that work for verizon.
You can try the standard "0000" also there is the possibility of it being the last four digits of your cell phone number. and if that doesnt work you can call your service provider and they can reset the code.
