+- Provide a good stable power supply. Read about [**powering your module**](https://github.com/vshymanskyy/TinyGSM/wiki/Powering-GSM-module).
 - Keep your wires as short as possible
 - Consider soldering them for a stable connection
 - Do not put your wires next to noisy signal sources (buck converters, antennas, oscillators etc.)

 When using ```SoftwareSerial``` (on Uno, Nano, etc), the speed **115200** may not work.  
 Try selecting **57600**, **38400**, or even lower - the one that works best for you.  
+In some cases **9600** is unstable, but using **38400** helps, etc.
