Review on 🌐 RoamWiFi R10 4G Portable WiFi Router Mobile Hotspot: Worldwide WiFi Device with 50GB US Data & 1GB Global Data for 60 Days, No Roaming Charges, Travel Pocket WiFi Hotspot MIFI – SIM Card not required by Tracey Gonzales

The device suits me and I like the cloud SIM. If you are using an Android app downloaded on an Android smartphone, please note that the TSID number is the last 8 digits of the IMEI number on the device box. Charge it via the USB port first. The TSID number is stamped on the bottom of the device, but it's VERY faint and hard to read, so it's easy to make a mistake here when trying to register it through the app. Otherwise, it seems to be performing well so far and has the unusual ability to switch from 2.4GHz to 5GHz for faster speeds with compatible devices. 2.4GHz is the default and works with almost anything that uses Wi-Fi to connect to the internet.
