Wi-fi data economy
Hi there!
Haven’t found anywhere about this matter:
my husband is a seafarer and the internet on board is very expensive,the internet connection is provided with the wi-fi router.
All programs that can upload or download data in background mode are switched off. Nevertheless the megabytes flow away in indefinite direction.
Is there any way to solve this problem of undetermined disappearance of megabytes in wi-fi mode?
Thanks in advance.
