Hello,
I have been with company since 1997 when it was (Alltel). I normally always upgrade when I am eligible and for whatever reason I was removed from the grandfather plan (unlimited data) I have been locked into over 17 years after upgrading this year to iPhone 6. I do not recall this information (data usage will change) advised prior to upgrading the phone. Now my son in college is over his DATA USAGE. I see this as being too expensive to continue. Did you guys know the data usage automatically changes without changing plans because you upgrade?
