There are several VoIP providers out there providing low international calling costs and rates. Ideally, you should choose a provider that covers the country you are most interested in. If you are located in North America and have family elsewhere in the world, then it’s in your best interests to find a provider that can offer great rates for the country you need. For businesses, you can sometimes get specific packages and negotiate with the provider for a great deal to cover your bulk calling to certain countries.
Some of the competitors
One of the main competitors is Google Voice. This full featured, rich services VoIP/SIP provider is one of the most popular on the market right now. Not only can it be installed as a program on a variety of devices, such as computers (Windows, Mac and Linux), but it is also usable on tablets and smart phones as well.
Skype is another very popular provider which has great rates all around the world. Like Google Voice, it also has great conferencing and video conferencing features. It also has extremely competitive low international calling VoIP rates. The only drawback compared to Google Voice is that it does not have some of the voice transcription and throwaway number generation services, but on the other hand it does voicemail and SMS to email or email to SMS very well.
Prepaid calling cards
Another good solution if you need to call a specific country is to get prepaid calling cards. These are more appropriate for family or friend connections, when you can get several hundred minutes to a certain country for a low rate. The service is accessed by dialing a local number using a land-line or a cell phone and will allow you to enjoy a low VoIP rate just like Google Voice or Skype.
