So i read online that if you grandfathered the unlimited data plan, you would be able to keep it and upgrade your phone by using the device payment plan. yknow the one where you pay the unsubsidized price of the phone in 12 installments and charging you $2 per installment. I went to several verizon stores asking about this and they all told me the same thing "i dont know what youre talking about but if you do upgrade your phone by paying the full price in installments, you will lose your unlimited data". After hearing that i asked several online specialist at verizon and they said i would be able to keep it. So what's the deal here? will i keep my data plan or lose it?
