Excellent products at affordable cost with excellent features

Great way to learn GSM

Was a very easy way to go from WIFI to GSM. The examples give you a great foundation to build upon.

Excellent smart modem device

The Lilygo T-SIM A7670E is a great device, very adaptable and with a range of features and capabilities. The documentation could be better, but I worked everything out in the end.

Perfect device for in the field!

Using the T-A7670E for continuous monitoring of a watering system where no WiFi, power, or other means are available. With solar panels and the GPRS I installed the T-A7670E for this purpose and since day 1 it functions as expected.
The libraries are sometimes a bit confusing as the A7670E is supported by libraries, but lacks some functionality like TLS connections.
The supplied headers with the device are too low, which means that you can't use a breadboard as the battery holder blocks that. I extended the headers, but alternatively, you could solder your cables directly to the device.
It helps to remove the SIM lock code before installing it in the T-A7670, however, libraries also support unlocking via a code. I removed the lock code on beforehand, so it started with making a connection right away.
