 ## Troubleshooting
 
+### Diagnostics sketch
+
+Use this sketch to diagnose your SIM card and GPRS connection:  
+  File -> Examples -> TynyGSM -> tools -> [Diagnostics](https://github.com/vshymanskyy/TinyGSM/blob/master/tools/Diagnostics/Diagnostics.ino)

 ### SoftwareSerial problems
 
 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.  
 Be sure to set correct TX/RX pins in the sketch. Please note that not every Arduino pin can serve as TX or RX pin.  
 **Read more about SoftSerial options and configuration [here](https://www.pjrc.com/teensy/td_libs_AltSoftSerial.html) and [here](https://www.arduino.cc/en/Reference/SoftwareSerial).**

+### ESP32 HardwareSerial
 
-### Diagnostics sketch
+When using ESP32 `HardwareSerial`, you may need to specify additional parameters to the `.begin()` call.
+Please [refer to this comment](https://github.com/vshymanskyy/TinyGSM/issues/91#issuecomment-356024747).

+### SAMD21
+
+When using SAMD21-based boards, you may need to use a sercom uart port instead of `Serial1`.
