Perforrmance will depend on usage as well as provider. 'Pocket wifi' hotspots provided by AirBnB hosts typically feature slower bandwidth and smaller fast data buckets on older WiMax networks with lesser coverage. Visitors coming later in the month may find that the fast data allocation has mostly been used up, with speeds throttling down sooner until the next cycle. Also, if they bring the loaned hotspot around then lose it, they can be hit with huge loss charges, sometimes in the hundred of Dollars!

Pocket wifis that you order yourself will normally feature more reliable LTE connections with bigger allocations of fast data, on average at least 1GB/day. However, you are still subject to the risk and cost of equipment loss, so It appears to be another profit opportunity for suppliers.
