Comment Comment by M95D MakerPhone / Ringo was far better.It was actually a real phone based on ESP32 + a GSM/LTE module. It could make phone calls, SMS, had games, apps, etc. at the level of what early 2000 GSM phones could do. Project is abandoned now.https://www.kickstarter.com/projects/albertgajsak/makerphone...https://github.com/CircuitMess/CircuitMess-Ringo parent M95D 2 years ago
