You want multi-function for your DroneMobile X1-LTE or X1MAX-LTE smartphone interface module for your vehicle’s remote start and security system, but you live in an area that doesn’t have access to AT&T wireless network. Problem solved — just swap out the Drone X1 module’s AT&T SIM card for DroneMobile X1-VZW-SIM Verizon SIM card, and you’re good to go with remote starting, GPS location, and security alerts from almost anywhere.
