I would like to buy the Nexus 4 phone from the google play store online to upgrade from my current Fido phone as Fido doesn't carry anything good. I have a plan and a sim card so if I buy the phone from google and stick my sim card in will it all work good? Sorry if its a dumb question, I have no clue how this stuff works. On the play store it does say the phone is "unlocked" so I guess that means something..? Thanks for the help
