To clarify: the 1500 landline share minutes are for calling or receiving calls to/from landline phones between 7am and 7pm on a weekday since cell to cell and nites and weekends are already free. It is nearly impossible to use all of these minutes since its like 29 hours. Yes...Sprint requires a data plan for its smartphones. And I realize that the plan probably costs more than you are already paying, BUT there may be a discount you are eligable for i.e. credit union member, military, state employee, many employers. And this 129.99 is the whole bill with two phones included...phones 3,4,5 can be added for 19.99/mo. The only additional fees would be taxes and insurance. There are no hidden additional charges for data/text/pic msg or anything else. As a trade I cancelled my home internet connection for 2 data capable cellphones and actually saved money.
Hope I summed up answers to all your questions!
