Hello i'm trying to build an arduino with a7 gsm gps geolocator that find coordinates and sending them with sms if i send it an sms first and i encountered some errors while compiling.
here is my code: (check update below first please).

Error compiling for board Arduino/Genuino Uno.
ps: The error happened when i used gsm library and the void RecvMsg() .
I'm really noob so i need help.
UPDATE: Replacing the SoftwareSerial library with AltSoftSerial fix this error and the code compiles succssfully.
Does this happen because SoftwareSerial and Gsm use the same interrupt pins ?
