Hi ... Great video ! Can the bell output be fed directly into arduino digital port to detect hi/low .. I want to trigger a relay and operate a factory analog bell .. Thank you Paul

How to connected to the network ?

This video, and many other tutorial videos, show the RxD pin connected directly to the Tx pin of a 5V Arduino ? The RxD pin on the SIM800L has a MAXIMUM voltage level of 2.8V. It needs a potential divider network to reduce the 5V signal from the Arduino to the 2.8V input on the SIM800L module. I have no doubt it works without, but it is stressing the SIM800L beyond acceptable limits, and I wonder how long it will last.

Exactly. Send the TX signal from the Arduino into a 1K/2K voltage divider and take the center tap to the SIM800L RX pin for a voltage of 3.3.
