With the advances in VoIP technology, the prices for international calling plans are much more reasonable. But it's important to compare prices among carriers since those not utilizing the newest technological advances in wireless and mobile services will be unable to offer you a competitive price for international calls. VoIP or Voice over Internet Protocol technology is making wireless and mobile services more affordable because it uses IP networks, like the Internet, rather than public switched telephone networks, to deliver voice communications and other messaging applications. VoIP converts analog voice signals to digital and translates the signal into Internet Protocol. On the receiving end, the process is reversed. The best money saving international calling plans are those that offer unlimited calls for one flat rate. With a flat rate, there's no need to keep track of minutes, peak calling times, or roaming charges. A flat rate means you can call anywhere, anytime, and talk for as long as you want. There are a number of different types of international calling plans available. To save money, do a price comparison based on your needs. Consider your overall international calling usage during a typical month. Look at how many minutes you use and how much you pay for them. Also factor in any additional surcharges and fees. Based on your volume of international calls, you can choose a plan that provides the most savings. Some international calling plans differ for a land line phone and a mobile phone. Often times, unlimited calling is provided with a home calling plan, while the price structure for mobile phones provides only a set number of minutes for a monthly fee. To save money, choose a plan that offers the best value, whether using a home or mobile phone. Current cell phones work on 3G technology, but the best plans offer 5G wireless technology. They operate on the Global System for Mobile Communications (GSM), which is the most common standard for mobile phones around the world. It enables mobile phone calls to just about anywhere in the world. For the best value in international calling prices, look for a service that utilizes digital GSM. International rates vary depending on the country you are calling. If you frequently make calls to several foreign countries, the best way to save money is with a flat rate and unlimited calling. Flat rate international calling plans are more economical than per minute plans traditionally offered by long distance providers. For many people, international calls are limited to when they travel or the occasional call to family and friends. As a result, they pay an exorbitant per minute rate through their long distance provider. Along with a rate that is charged per minute, additional fees and taxes are levied by the government. To save money on international rates, shop around for the best deal for the country you call most often, or look for a mobile service provider that includes unlimited calling or texting, along with unlimited live chat or Skype.
