While no longer Apple's flagship, the iPhone 6s is a solid starter phone for those on a budget. If you're looking for a cheap iPhone, Sprint has the best iPhone 6s prices around.

Currently, Sprint is offering the Apple iPhone 6s (32GB) for $99.99. In comparison, a refurbished, unlocked iPhone 6s sells for $154 on Amazon.

The iPhone 6s is powered by Apple's A9 chip and has a 4.7-inch Retina display. There is a single 12MP camera on the back that supports HDR and 4K video, and the front camera has a 5MP lens that supports HDR and 720p video. This upgraded model also offers 32GB of storage instead of the standard 16GB.

It also includes Touch ID for secure authentication as well as Apple Pay. More importantly, it can run Apple's latest iOS 13.

Sprint's promotion will end while supplies last.
