Wells Fargo is the latest bank to add mobile service capabilities for its customers. The bank follows other financial institutions like Citibank, Bank of America, Wachovia, and Sun Trust. All of these banks have added similar mobile services within the past several months. Mobile bank services are provided free of charge and allow customers to check their balances, review recent transactions, transfer funds between accounts, and pay their bills. Many of the services also provide a way to find the nearest bank branch office or ATM as well. The move to mobile banking gives consumers greater convenience and adds another function to the ever-evolving cell phone. Mobile banking is a step along the way to transforming the cell phone into an 'e-wallet' that will allow individuals to make payments with it. According to Jim Smith, executive vice president and managing head of Wells Fargo Internet Services Group, there has been a revolution in mobile devices in the past four or five years, and customers are more willing to try out new things. Smith believes the devices have developed to a point where customers value advanced features like mobile banking. There are three ways customers can use the services. They can log in to their accounts via the bank's mobile website using the cell phone's browser, download an application to the phone for quicker viewing and fewer data charges, or do their banking tasks via text messaging on their cell phones.
