We are offering a 15-day free trial for every paid plan. Entering billing information is not required. In order to transfer your trial account to a paid one after initial 15 days you should pay a monthly fee.
When you upgrade your free account to a paid one you will automatically get a 15-day free trial that works as mentioned above.
If you do not pay for the next month your account will be automatically switched to a “free” mode.
Yes, you can change a plan on the “Billing & Settings” page (on the desktop interface). If you're changing from an “Optimum” plan to a “Premium” one, the remaining days of the “Optimum” plan will be reduced by half (since the “Premium” plan is twice expensive as the “Optimum” one).
The payment processing system that we're using ( Plimus ) accepts payment by MasterCard, Visa, EuroCard, American Express, Discover/Novus, Diners Club, JCB, Switch, Solo, USD Checks, Eurochecks, Wire Transfers, PayPal.
