Turn off aeroplane mode to make a call on Moto g2
It appears you are using the incorrect firmware for your device... Your device is Retail India (RETIN), but the firmware image you are using is Retail Latin America (RETLA). The correct firmware for Retail India is RETAILDSDS (don't ask me why, I have no idea what it stands for other than Dual SIM something).
A mismatch of radio firmware to the hardware in your device can cause the operating system to think you are in airplane (aeroplane) mode.

Assuming you have the proper drivers and fastboot installed, use this file and extract it to your fastboot directory, or any known directory if fastboot is in your path. Open a elevated privilege command window, in Windows click Start and type cmd and then right-click on cmd.exe and select Run as Administrator or in Linux open a terminal window and enter sudo -i and your password, and navigate to the folder where you extracted the firmware file's contents. 

Then enter these commands manually, one at a time (it's OK to copy/paste them individually, just don't do the whole thing at once):

fastboot oem fb_mode_set
fastboot flash partition gpt.bin
fastboot flash motoboot motoboot.img
fastboot reboot-bootloader
fastboot flash logo logo.bin
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash system system.img_sparsechunk.0
fastboot flash system system.img_sparsechunk.1
fastboot flash system system.img_sparsechunk.2
fastboot flash system system.img_sparsechunk.3
fastboot flash modem NON-HLOS.bin
fastboot erase modemst1
fastboot erase modemst2
fastboot flash fsg fsg.mbn
fastboot erase cache
fastboot erase userdata
fastboot oem fb_mode_clear
fastboot reboot  

If ANY step fails, or gives any response other than OKAY, check the command and try again. In some cases the modems will need to be done be done 2-3 times. If you get a "Preflash validation error" on the partition table (gpt.bin) it is OK to skip that file (ONLY if you get that error), but you must do each step after that.

The first boot on Marshmallow can take a long time, give it at least 20 minutes after the final reboot to come up to the setup wizard.

This should bring the modem/radio firmware in line with the boot image and the hardware radio and allow you to get normal service again.

Good luck!
