Let me start by saying this little gadget has saved my sanity during business trips. The Netgear Unite Pro is a refurbished 4G LTE mobile hotspot that's GSM unlocked, meaning you can use it globally by swapping SIM cards. I've tested it across three continents, and it's been surprisingly reliable.

The setup was a breeze - just pop in your SIM, configure the APN settings (took me 2 minutes), and you're online. I love that it supports multiple network bands, making it versatile for different carriers. The battery life is impressive too - I got about 8 hours of continuous use before needing a recharge.

Where this device really shines is in hotels with terrible WiFi (which seems to be most of them). I've hosted video calls from conference rooms where the hotel WiFi couldn't handle email, while my hotspot delivered stable 10Mbps speeds. The ability to connect up to 15 devices means my whole team can work simultaneously.

Now for the downsides: The WiFi signal strength could be better. In larger rooms, I sometimes had to position the hotspot carefully for optimal coverage. Also, while it claims to support phone charging via USB, I wouldn't recommend it - the battery drains way too fast.

A pro tip: Get an external antenna if you'll be using this in areas with weak signal. I bought a $20 antenna that boosted my speeds significantly in rural areas and inside concrete buildings.

One thing to watch - some users report issues with AT&T SIM cards (though mine worked fine). If you're buying specifically for AT&T service, do some extra research first.

For digital nomads or business travelers who need reliable internet anywhere, this is absolutely worth the investment. Just pair it with a good data plan from your preferred carrier (I use T-Mobile's global plan), and you'll never have to suffer through terrible hotel WiFi again.
