Well, looks like if you want the SIM-Free iPhone SE and plan to use it on Sprint you can forget about it.
Always something with this carrier.

The SIM-free iPhone comes without a wireless contract commitment or carrier financing. It doesn’t come with a nano-SIM card for iPhone SE. And because it’s unlocked, it isn’t tied to one carrier, so you can get a nano-SIM from any supported carrier, such as AT&T, T-Mobile, and Verizon in the United States. The SIM-free iPhone SE is not compatible with Sprint’s network. To use iPhone SE with Sprint, you need to select Sprint as your carrier when you purchase your iPhone.
Always something with this carrier.
