Verizon Wireless, the biggest U.S. mobile provider, will stop offering customers unlimited data services for a set fee on July 7, meaning higher prices for heavy users of services such as mobile Web surfing.

Under the new terms, new customers who limit their data use to 2 gigabytes (GB) will have to pay $30 a month, according to the venture of Verizon Communications and Vodafone Group, which currently charges its customers $30 per month for unlimited data use.

Customers who use more than this will have to pay $10 for every extra Gigabyte of data they use, according to Verizon Wireless spokeswoman Brenda Raney.

Heavy data users could also sign up for a $50 per month plan for 5 GB or $80 a month for 10 GB, Raney said.

Verizon Wireless is following in the footsteps of AT&T Inc, which stopped offering unlimited data services last year. Unlike AT&T, Verizon is not offering any new cheaper option for low data users.
