You can start anytime. If it's before 15th, your traffic allowance and plan price will be calculated proportionally to the remaining days of the month. If you start from 16th on, we'll ask you to pay for the remaining days of this month + the next month in one payment. This way we won’t bother you with making two payments just a few days apart. To start your preset monthly plan, simply select your preferred traffic plan in the Billing section of your Client Panel and enter your credit card details. Once done, you'll be all up and running and your monthly plan will be set to auto-renewal.
