The Gmail service is designed to allow users to access their mail and keep it synced up, whether its checked via a cell phone or a PC. And although the Gmail service is free, users still have to foot the bill to get Internet access via their carrier, in order to click onto the Google site.
And Internet access is not cheap. Some carriers, meanwhile, are offering cheaper, hybrid pricing plans, where users can access some limited Net information, such as Yahoo or AOL mail, sports scores and weather. But those plans don't allow for free roaming on the Internet.
