Consumers have begun to move away from two-year contracts and embrace the prepaid smartphone market. In response to this growing user base, Verizon Wireless this week announced that it is increasing its data allowance for prepaid customers. The carrier’s new plans offer unlimited talk and text with 2GB of data, up from 500MB, for $60 a month. There is also a plan with 4GB of data, up from 2GB, for $70 per month. The increased data allowance is available now to current customers, and will be available to new customers beginning June 6th. AT&T also recently announced a new prepaid service in select markets, known as Aio Wireless, which offers unlimited talk and text with 2GB of data for $55 per month, or 7GB of data for $70 per month.
