SmartSIM 4G LTE WiFi Mobile Hotspot
A pocket 4G hotspot with a 6000mAh battery, up to 10 connected devices and a data-only SIM included, at $69.99.
Is the SmartSIM 4G hotspot worth buying?
For a traveler who wants one pocket Wi-Fi for a family, it is reasonable. The 6000mAh battery is the headline, with the listing claiming more than 12 hours of use, plus a lightweight 0.3 lb body and Ethernet and USB ports. It is a single-band 2.4GHz Wi-Fi device, so don't expect 5GHz speeds. Claims such as the 5-year warranty come from the product page, so keep your order record.

A solid pocket Wi-Fi for the price
It is not exciting, and that is fine. The battery size is the main reason to pick this one over a basic hotspot. Buy it if you need a shared connection on the go and don't mind 2.4GHz.
