Probably the best way to check network coverage we've seen.

Did you ever check to see which carrier offers the best coverage in your town? Or – worse – did you ever wonder which carrier’s pre-pay SIM you should buy when you go on vacation? It’s hell, right? Those maps are so deeply hidden in the carriers' sites that it’s almost like they didn’t want you to find them.

Enter OpenSignalMaps, which is not only an independent map showing you the 2G, 3G and 4G coverage in much of the world, but is also just about the sleekest and slickest map/info site we’ve ever seen. And it works just great on iOS devices.
