On October 16th, 2015, Sprint's unlimited data plan will get a $10 rate hike going from $60/month for unlimited talk, text, and data to $70/month. As the plan stands now, Sprint offers the lowest rate among the 4 major national carriers for unlimited 4G LTE data. T-Mobile's unlimited ((T-Mobile calls unlimited 23 GB before data prioritizing)) plan costs $80/month while AT&T and Verizon do not offer unlimited data plans. The new price allows Sprint to increase its profits while still remaining one of the cheapest options for unlimited data among all carriers and MVNOs.
Current Sprint customers will be grandfathered in and this will be able to keep the $60 promotional rate plan.
To get iPhone users to jump ship or upgrade their phones, the carrier is currently offering the plan, phone included, for $61/month if you lease an iPhone 6s 16 GB variant through Sprint. If you want the iPhone 6s Plus, the plan will run you $65/month. Taxes and fees are not included in the pricing. To qualify for the special pricing, you must trade in an iPhone 6 or iPhone 6 Plus.
Current Sprint customers who are upgrade eligible and potential customers who don't own an iPhone, can trade in any other smartphone and get a promotional rate of $15/month for an iPhone 6s 16GB, (regularly $22/month without a trade-in) , or $19/ month for an iPhone 6s Plus 16GB, (regularly $26/month without a trade-in).
This promotional offering will run until December 31, 2015.
