Do a Google search 'how to bypass Google account on my phone'and you will see numerous instructions as to how to unlock your phone.
go to a google service, on another phone or computer, such as gmail and do a forgot password procedure to reset your google password.
@SillyGogo what do you do if you don't know your email address?
hmm, i think from memory, there is a forgot email option too...but you might have to have a secondary email set up. If OP can get into the Alcatel phone and open gmail then the email address is the login email or go into settings under account..look for google then email login should be there.
