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

Raspberry Pi successfully configured to connect to T-Mobile via ppp0, replacing the old T-Mobile Jet 2.0. Definitely faster than the old HSPA+ modem. The wwan0 interface appears when the modem is connected, but I couldn't get it to work with T-Mobile, which is a shame as it would be faster than ppp0. So four stars, not five. If I find a way I will revisit this review. Update: I was able to use the Raspbian qmi-network software to connect to T-Mobile via the wwan0 modem interface. I am very satisfied - great price.
