With both the Pepwave and WFR you need to verify that the cellular equipment you want to use is supported. Neither device supports everything....but that would be true for any cellular router.

The WFR with Boost is more complex to set up, but it performs better. Everything is a tradeoff. In my experience you will have to "fiddle with" the WFR more, over time, than the Pepwave. But for maximum performance you can't beat the WFR with Mobile Boost.

Nothing will beat haveing a powerful CPE on the roof. For example, we are currently in the SKP park in Summerdale. While there is (paid) Tengo service in the park that is easily picked up, I prefer to use my aircard or free wifi. I searched for open wifi in the area with just my laptop and saw nothing. With the Pepwave I also saw nothing. I then used a CPE with a directional antenna to search and found 4 open connections at houses near the campground. One tested very fast, but appears to be almost 1/2 a mile away. That is an example - I do not use connections of this sort except in emergencies, but having the ability to connect to them is sometimes important. Personally, I don't believe in "using" private bandwidth without permission....businesses, yes, but not private.
