So does your board have a GPS receiver attached to the G350, or not?

Are you sure all the EVK combinations support GPS? Check the AT manual for the modem.

What GPS receiver are you using?
How is the GPS module connected to the SARA-G350 -- what is the spevific wiring and port?
Is this a u-blox EVK or your own project?
Where is the green light that is flashing-- on the GPS module, on an EVK, on the SARA subassembly, elsewhere? Do you have schematics?
