Hi friends . I am trying to communicate with my sim800l gsm to pin 8,9 to arduino nano , i can't . On 2,3 works fine , but i need 2,3 for interrupts. or can i use other pin exept 2,3 , and how, thanks .

From what I read at this webpage --

such is possible, since it's using SoftwareSerial( )

Assuming, given your lack of details, that this --

is how you have things wired

change
SoftwareSerial mySerial(3, 2); //SIM800L Tx & Rx is connected to Arduino #3 & #2

to
SoftwareSerial mySerial(9, 8 ); //SIM800L Tx & Rx is connected to Arduino #9 & #8

and then
move the wire connected to 3 over to 9 and then move the wire connected to 2 over to 8.
