The next time you’re in a new place and looking for the mobile carrier with the widest coverage, head over to OpenSignal and they will show you the major mobile providers in the area and their coverage.
What is unique about OpenSignal is that it also relies on community generated maps of both WiFi and mobile receptions — which means you can now find out if your house is located in the black zone (i.e. no reception zone) between 2 carriers.
Other benefits – a speed test and also a compass signal to direct you to an area with better coverage.
Dont you just love the Internet!
