Verizon increasing data caps on pre-paid plans
Now, without raising the price of the service, Verizon has increased the data cap on both tiers of service to 2GB for the $60 a month plan, and 4GB for the $70 a month plan. To reiterate what we said above, the changes start immediately for existing Verizon customers and June 6th for new customers. And yeah, we should tell you that the pre-paid plans are for 3G service only.
