Currently my wife and I have an android smartphone with a data plan and a regular phone. Is there a way to have an android tablet and have that use the data plan we already have (which is unlimited) and then just have a second regular phone which would use the number the smartphone currently has - or do we have to get a third LINE for the tablet. Since the tablet really doesn't make phone calls it's confusing. Actually I find most things on the website confusing when trying to figure out options. What I am saying is, is there a way to use the tablet with the data plan so that all we buy is the tablet and a second regular phone (not a smartphone) for phone calls but don't add anything to our monthly bill.
