New Sprint Family Share Pack plan offers 12GB of data on up to 10 lines for $90 per month

Sprint has just introduced a new tier into their Family Share Pack plans, which gives customers 12GB of high-speed data, unlimited talk and text, which can be shared between up to 10 lines for $90 per month. Each tablet added to the plan will cost an extra $10 per line, and each mobile broadband device added to the plan will cost an additional $20 per month.

Sprint explains:

Sprint is reducing the data access charge on the $90 Family Share Pack plan from $25 to $15 for handsets. For customers switching their number to Sprint from another carrier, Sprint is waiving the access charge for handsets, tablets and mobile broadband devices on 12GB or higher data allowances for up to 10 lines for one year.⁵ All devices must be purchased through Sprint Easy Pay, Sprint Lease or the Sprint iPhone for Life Plan. A family of four will save $720 in data access fees for the year.

Also, for customers who are porting their numbers over from another carrier and are planning to activate on this new plan, Sprint will give you an American Express Reward Card up to $350 for each line to help you buyout your old contract. This entire promotion will only last until March 12th.

Considering the price of other similar data tier plans throughout AT&T, Verizon and T-Mobile, this might be a good option if you have more than a few people willing to switch.
