Hey,

I am currently using sim800l v2 , but the ring led restart every 10-12 seconds and the network led blink every second (when the ring led start blinking).

for the wiring I connect
5v >>> 5v
GND >>> GND
pin 10 >>> TX
pin 11 >>> RX

could anyone help me to solve this problem??, should I use an external power source(like a battery 5v)?

Probably, yes. I read in the SIM800L datasheet that transmission bursts can draw up to 2A from the power supply. If you're powering that module from the Arduino, you may run into trouble.
