Let me start by saying this little gadget has been a lifesaver during my recent trips. The VSVABEFV R816US is a compact, portable WiFi router that supports 4G LTE networks, making it perfect for travelers who need reliable internet on the go. It’s unlocked, so you can use it with various carriers like AT&T and T-Mobile, which is a huge plus.

The Good: When it works, it’s fantastic. I used it in Mexico and Jamaica, and the connection was stable enough for video calls and streaming. The battery lasts a decent amount of time (thanks to the 2400mAh capacity), and the screen display is handy for checking signal strength and data usage. Plus, supporting up to 10 users is great for group trips.

The Bad: Oh boy, where do I start? The charging port is flimsy—mine started acting up within a week. Some users reported it shutting down randomly, and I experienced this too. It’s frustrating when you’re in the middle of something important. Also, setting it up isn’t as plug-and-play as advertised. You might need to tweak APN settings, which can be a headache if you’re not tech-savvy.

The Ugly: Compatibility issues are real. Not all SIM cards work seamlessly, especially virtual or IoT SIMs. One user couldn’t even get their carrier to recognize the device’s IMEI number! And if you lose the manual, good luck figuring out how to set it up—the interface is barebones.

Final Verdict: This router is a mixed bag. When it works, it’s a travel essential. But the inconsistent performance and build quality issues make it risky. If you’re willing to gamble (and maybe buy an extended warranty), go for it. Otherwise, consider spending more on a reliable brand.
