There are a number of reasons why offline maps are a good addition to your smartphone arsenal. For starters, you can't always rely on network access or Wi-Fi. Usually when you want maps, you've found yourself in an area you're not so familiar with which may also have poor reception or none at all.Then, there's cost. Why pay data fees to repeatedly load the same map information every few days? Offline maps let you download once and visit again and again. And half the time they're free.
