Banks are offering mobile banking services free of charge to their customers to encourage them to give this new service a try. That means you can save money and save time by taking mobile banking out for a test spin. Banks are willing to offer these services for free because they can reduce administrative costs when customers can conduct their business electronically.
One word of caution: If you're using a smartphone, check with your service provider to make sure that your data plan doesn't tack on extra charges for text messages or downloads. If you don't have the right service, the charges can add up quickly; a little advance planning can help you avoid any unpleasant -- and expensive -- surprises.
