Review on 🔓 Unlocked Huawei E397u-53 USB 4G LTE Modem - Exclusively for T-Mobile US, Worldwide Hotspot Service Required by Rob Rogers

So far on a test day this device works great for what I needed it for.1. Works great on TMOBILE LTE. I only get 5MB with it, but the connection to my location isn't great.2. In my ASUS router (RT-AC3200-Merlin FW) it mostly works well for WAN backup. That's why I really wanted this device. ASUS picks it up and requires little to no setup to get up and running out of the box. Fails quite successfully, I had at least one error where I had to reboot the router, but it worked every other time. As an added bonus, it has a connector for an external antenna if you want to use it somewhere that requires an external antenna. The manual claims it's used for "external RF testing," so YMMV has successfully used it as an external antenna, but it's worth mentioning.
