… it’s actually just a website that lets you “Find” or “Add” your cellphone provider, signal strength, and location on a map from Google Maps. The more popular it gets, the more accurate is the information. So it’s not entirely lame. Just needs more people to give it the content it can provide to others.
So if you plan on visiting somewhere in the US and want to check out if you get reception on your cellphone, check out SignalMap.com and go ahead, leave behind the strength of your cellphone signal and provider.
