2. Use calling cards:

3. Use a callback service:
Callback services are a type of VoIP service that allows you to make phone calls at a reduced rate by having the call routed through a third-party server. When you use a callback service, you'll first call the callback service, which will then connect you to the person you want to call. This method can often save you money because you only pay for the call from the callback service to your destination.
