I have my brother's old phone that i really like and want to switch my phone with it. My brother did use Bell service which i am using for my phone. but the thing is that my brother doesn't use that phone anymore. When i try using his phone, for instance calling, it doesn't work. it says "no Sim" in the main page of my brother's phone., When i switch my Sim to my brother's... it asks for a pass before i can get in and i dun know the pass. I never set up one. Will the phone be useable after i insert the sim card or will i have to do something else? MY phone is Nokia c6, his is HTC google android!
