International calls are phone calls made from one country to another. These calls can be made using landlines, mobile phones, or internet-based services. The cost of international calls varies depending on the service provider and the countries involved. To make an international call, you typically need to dial an international access code, followed by the country code of the destination country, and then the local phone number. For example, calling the United States from Canada requires dialing 1 as the country code. Many people use VoIP services to reduce costs when making international calls.
