Air780e wake up by sms

Hi , 

I want to use air780e 4g module .my module has only these pins. 

Vcc,gnd,bat,Rx,tx,dp,dn,boot,led,en

I need to wake it up by sending sms , but my module has not any io pins , 

My question is how to wakeup it and trigger mcu which is also in sleep to wakeup and do the actions for my project .

One way is to send sms and by at command set the module to change state of an io port but my module has not io pins.

Is it possible by at command to modify dp or dn or led pins to be as output and when sms comes changes their state ?

Thanks a lot
