## What it is
TinyGSM is a small Arduino library for controlling GSM/GPRS/LTE cellular modems such as SIM800, SIM900, SIM7000, Quectel, u-blox, and XBee modules. It provides a client interface for TCP connections, HTTP requests, and MQTT over cellular networks on microcontrollers like ESP32 and ESP8266.

## Use cases
- connect an Arduino to the internet over a SIM800 GSM module
- send MQTT messages from ESP32 over cellular
- make HTTP requests from a microcontroller using GPRS
- use a SIM7000 LTE modem for IoT data connections
- add cellular connectivity to an embedded project
- talk to Quectel or u-blox modems from Arduino code

## When to choose
- you need lightweight cellular connectivity on Arduino-compatible hardware
- you want a proven library supporting many GSM/LTE modem chips
- you need TCP/HTTP/MMQT client classes that work over a modem

## When to avoid
- you need WiFi or Ethernet connectivity instead of cellular
- you are not using an Arduino-compatible embedded platform
- you need advanced modem features like voice calls or SMS-heavy workflows

## Facets
- artifact type: library
