How does the billing cycle work?Last Updated: February 14, 2019
The billing cycle period begins at the date of the first payment. The plan will be active for a full calendar month. For example, if you purchased Regular plan on September 7th, your account will be active till October 7th and you will be charged the same date.
When switching plans before your current subscription has ended, your unused traffic will not carry over (will be reset to 0GB) and you will be charged the full amount for your new plan.
