TTGO ESP32 + GSM 800l

The TTGO T-Call is a new ESP32 development board that combines a SIM800L GSM/GPRS module. The new board combines ESP32 WiFi & Bluetooth WiSoC with SIMCom SIM800L GPRS module, and also happens to rely on a USB-C port for power and programming instead of the more common micro USB port on this type of hardware.

TTGO-ESP32-GSM-004

Besides Wi-Fi and Bluetooth, you can communicate with this ESP32 board using SMS or phone calls and you can connect it to the internet using your SIM card data plan. This is great for IoT projects that don’t have access to a nearby router.
