How do I know my service plan/cost?

The cost of virtual numbers, call forwarding, as well as outgoing calls and/or SMS, can be found in the "Pricing" section.
In the calculator you can choose the country, type of number, city/operator for the number you want to buy. You can also check the cost of forwarding to the destination you specified and the cost of outgoing calls and/or SMS to the countries you are interested in.
