A screen can show useful connection and data information without relying only on a phone app.
App control and a claimed capacity of up to 10 connected devices suit sharing a mobile connection while travelling.
USB-C charging is listed, and the stated 4G download ceiling is up to 150 Mbps.

Cons

This is a 4G LTE hotspot, not a 5G mobile router.
Wi-Fi is listed as single-band 2.4 GHz, which limits it to that band rather than offering dual-band Wi-Fi.

Customer feedback praises setup and coverage but reports mixed experiences with speed, signal, reliability and value. The technical details also list 10 ports and 1 Gbps LAN bandwidth without explaining how those apply to this portable hotspot, so confirm these details if they matter to your purchase.
