As many of you might have faced an issue that you want to create a new Gmail account but GOOGLE through this message on your face that you can't create new account without verifying your phone number .....and you thought to yourself 'you know what i will put phone number and i am good to go'.
But once you do that GOOGLE starts to whining "oh ho look man i know this phone number is valid but here's a thing i know some accounts verified using this number ...so...! here's a thing i'm not letting create anymore accounts with this number".
And you would be like
since it's your phone and you need more accounts then there shouldn't be any limits on creating more accounts .So that's where i come in and tell you
You know what? you can verify unlimited accounts as you want with just a single number
I know ...I know what you must be thinking right now 
But believe me its true and possible it's just a simple trick that you need to implying.And the trick is that if you used your phone number to verify account then just delete that number from your account once account has been verified .Hence you can create as many accounts as you want.
