GSM signal strength Sim900

I use Mega and sim900, for autostarting a car’s engine.
I suspect that the connection of the antennas and the sim900 is bad.
Is there a function that will show the GSM signal strength?

Blynk Server

Probably, but it will not be a Blynk specific function… Google for some code that works for the SIM900 library.
