Long-Distance Calling refers to the ability to make telephone calls over significant distances, often between different cities or countries. This service allows people to communicate with friends, family, or business associates who are far away. Long-distance calls typically incur higher charges than local calls, depending on the service provider and the distance involved. The technology behind long-distance calling has evolved over the years, from traditional landlines to modern VoIP (Voice over Internet Protocol) services. Today, many people use mobile phones and internet-based applications like Skype or WhatsApp to make long-distance calls, often at little to no cost.
