we also settled on the number, and the implementation of, privacy switches on the phone – there will be 4 switches in total: for the i) BT/Wifi module, ii) the modem, iii) cameras (front/back) and iv) lastly for the microphone.
and right on the pinephone page it says it has this chip: Key Benefits
● LTE Cat 4 module optimized for M2M and IoT applications
● Worldwide LTE, UMTS/HSPA+ and GSM/GPRS/EDGE coverage
● Multi-constellation GNSS receiver available for applications requiring fast and accurate fixes in any environment
● Feature refinements: supports DFOTA*, eCall and DTMF*
● MIMO technology meets demands for data rate and link reliability in modem wireless communication systems
Sounds like a cell radio to me. As things stand today, we expect a fully functional prototype in August
