are there any plans on sprint that allow sharing of minutes but not data? the only plans i see available on the website that include family plans force the primary and secondary lines to have the same restrictions (i.e. unlimited data for both, unlimited text for both, etc.). i really only need 450 landline minutes to share with my dad but he doesn't want the internet or texting. any tips or am i screwed into having to get the $130 (minus any discounts) with 1500 minutes plan? thanks in advance.
