There are so many times every day that you're connecting to cellphone towers or Wi-Fi locations that you don't even think about it much anymore. Unless, of course, you can't find a connection.
If you're traveling for work or just for fun, you may enter an area where you can't find a connection, or can't find a strong signal. If you're moving or if you're considering switching carriers, it's best to first check the strength of a provider where you live.
The same goes if you work remotely. One day, the coffee shop down the road has a great signal, but the next day you can barely connect.
You can try walking around or driving around looking for strong signals, but that's a waste of time. A much better way to find strong cellphone signals and Wi-Fi connections is OpenSignal.
The company's mission is to "become the global authority on wireless networks." Which says a lot. But you're just looking for a strong connection, right? OpenSignal could not be easier to use.
Go to the site or Android or Apple app, type in your location and OpenSignal almost instantaneously shows you an interactive map with bright colors on it. Those bright colors represent cellphone coverage in that area; they go from blue for a weak signal up to deep orange for a strong signal.
