According to a new report, Verizon may be planning a crackdown of sorts on customers it deems to be using "an extraordinary amount of data" each month. Specifically, Droid Life reports that, according to its sources, unlimited data customers that Verizon flags as using too much data will have an opportunity to move to a different plan starting July 21.

Verizon expected to crack down on unlimited customers using 'extraordinary amount of data'

From Droid Life:

According to sources of ours, Verizon is working on an Unlimited Data Plan Migration for the highest unlimited data users on their network. Starting tomorrow, July 21, Verizon will begin notifying users who have been flagged as using that "extraordinary" amount via mailer and through bill messages and explain to them their options to stay with Big Red.

According to the report, users who are alerted will have until August 31 to switch to a tiered plan, otherwise their line may be disconnected. If disconnected, the customer will have up to 50 days to reactivate with a new plan, the report says.

It remains unclear what Verizon would deem as "an extraordinary amount of data," but we should know more if and when the carrier moves forward with its plans.

Update: Droid Life has also now received a statement from Verizon regarding this move:

These users are using data amounts well in excess of our largest plan size (100 GB). While the 100 GB plan is designed to be shared across multiple users, each line receiving notification to move to the new Verizon Plan is using well in excess of that on a single device.
