The GPS should be kept always on because its cold start takes minutes to fix the satellites despite the native MLS packages and several GSM/Wifi position backend services has been installed and running.
Configure the A-GPS as described here:
Sometimes when after a reboot or after an airplane mode one of the two SIM or both, but usually one, has problem in finding the network and into the native Setting → Mobile network, the related Network field remain in searching. In this case degrade the network mode to 2G only. After the network will be found, switch to prefer 3G and then after the network will be found again, switch to prefer 4G. This seems a slower approach but in fact, it works around the problem⁰
