My son cant remember his unlock code for his samsung D900i, The phone keeps sayind enter phone unlock code ?

its the last 4 digits of his cell phone number.

the phone company would give it to u for free but u have to call it on another mobile phone and make sure he does not try 2 many times because they might block d phone meaning it wuud not work in the uk/usa

try 0000 1234 or the last four of the phone number..which is prob it

Call the phone company, they might have some ideas or can probably give a code/unlock it for you

.......try the last 4 digits of his phone number.....

tell him to call his service provider...they will give him the code or reset it. I locked y sisters phone once trying to guess hers and thats what we did..it works

its the last 4 digits of the cell number

The whole point of the lock is so it cannot be bypassed however you probably could try to get it unlocked at the store you got it from depending on how old it is and if you have registered it or have proof of purchase

i locked my phone and forgot the code once too. All i did was take it to the verizon store (or whatever service you have) and tell them what happened. They simply reset the password for me, but i don't know if there's a way to do it on your own.
