After being around for years, Freematics ONE+ Model B has got a refresh recently. It now comes with SIM7070G LTE-M module. LTE-M gives a longer range, lower latency, lower power consumption, full mobility and roaming support, which makes it ideal for automotive applications that operate across multiple regions. SIM7070G has global LTE and GSM network support. Comparing to SIM7600, it has no UMTS support meaning it has a limitation in areas which rely on 3G network (no 4G or 2G coverage, like some rural areas in Australia). Model H still uses SIM7600.
The Arduino library for Freematics ONE+ has been updated for application code to support both SIM7600 and SIM7070 effortlessly. Now same code can work with SIM7600 and SIM7070 without pre-configuration as cellular module is automatically identified at runtime. The telelogger (reference application code) has been significantly improved with iOS/Android app support via BLE and seamless WiFi/cellular network switching. By the way, Freematics Builder is still your best helper to use telelogger.
