Pros and cons

Pros

Dual WAN and mobile-broadband use gives it a practical role as either a main connection or backup.
A Nano SIM slot and claimed support for up to 32 Wi-Fi devices suit a shared home connection.
Guest networking and parental controls provide basic network-management options.

Cons

Wi-Fi is described as up to 300 Mbps, so buyers needing higher local wireless throughput should compare routers with stronger stated Wi-Fi capacity.

What to know before buying

Listing details to confirm

The listing is inconsistent about wireless capability: it calls the router N300 and claims up to 300 Mbps Wi-Fi, but also lists Dual-Band, Wi-Fi 7 and 802.11.be. Confirm the exact wireless standard and band support for the selected unit. Its title calls it portable, but the supplied details describe a power-adapter router and give no battery specification. The 150 Mbps LTE and 300 Mbps Wi-Fi figures are stated maximums, not guaranteed real-world speeds. An activated Nano SIM and usable mobile coverage are required for LTE access.
