A:Answer It will all depend on your contract or prepaid plan. It will also depend on whether the phone shares data from a community "bucket" -- like a Family Share Plan -- or if it has its own data plan.
The question you posted looks like it's tagged to the iPhone 6+ for Verizon... if this is indeed the case and your service is with Verizon Wireless, the easiest way I know to determine this would be to go to the Apple AppStore and download the My Verizon app (it's free). The direct web link is: https://itunes.apple.com/us/app/my-verizon-mobile/id416023011?mt=8
When you log in, it will give you all of the details of the account -- whether it's a single phone or part of a family plan.
Good luck! And enjoy the new phone!!
