Okay, so I got this portable hotspot hoping it would be my travel buddy. The idea of connecting up to 10 devices sounded awesome for group trips!

First off, the speed is decent when it works—I hit around 100-150Mbps in areas with strong signal. The 300Mbps claim feels a bit optimistic though.

MAJOR WARNING: It DID NOT work with my US carrier SIM card. Had to dig through forums to realize it's probably region-locked despite being 'unlocked'. Total bummer when you're already on a trip.

The battery life is actually good—lasted me through a 6-hour train ride while streaming. But the setup? Not plug-and-play at all. Had to disable PIN codes and manually tweak APN settings like some 2012 smartphone.

Final verdict? Might work if you're in Asia/Europe (check bands carefully!), but for US/Mexico travelers? Save your money and frustration.
