I choose this one over the more expensive 4G version because I only use it for voice and text so it is more than adequate for that, and besides, there is no 4G where we camp.

Works great with my Nexus 6 4G smart phone.

When used in my truck in a remote area in the Virginia mountains with an iphone, the signal went from no service to 2 dots out of 5 with solid 3G service
