When GSM signal is lost, any GPS tracker save positions on a SD card?

I have some area were no GSM signal, so why providers not have a way where these black spots saved in sd card and later when signals and data avaliable , these info imported to clouds to fill-in the missing spots

Hello, IbrahimAl-Siyabi

It depends on the device you are using. Most often, the tracker accumulates messages when the connection is lost, and after the connection is restored, these messages reach. Also, in some trackers, it is possible to set a mode in which you can turn on or off the accumulation of messages in case of loss of communication. You can check this information with the manufacturer of your tracker
