Bought this for a project and then changed direction once my overall plans changed. I have put in a SIM and tested it out and it works great. Bear in mind, this is 4G only. As the manufacturer description states below it only works for AT&T and T-Mobile. 

What you see is what you get:
* Amplimax 
* Power Plug
* POE Injector and LAN block
* Original flat Ethernet Cable to plug this into either a router/switch/computer. 

Please also note: picture of the back indicates I drilled four holes to be able to mount it as I needed for my project. The four extra holes do not affect performance of the unit itself nor will they prevent you from using the mounting bracket as you see fit.

This is a USED model. As such it does not come with any warranty nor will I take it back as a return. As the picture shows it powers up and operates normally. The particular message on the unit in the picture indicates that there is no SIM installed.
