Expert tip
It’s important to narrow down what you actually need from a VoIP system first, as there’s quite a range of different functions on offer from different providers and international call apps.
If you’re just an individual looking to stay in touch with friends and family abroad, the free app-to-app calling options on this list are going to be your best options. Popular communication platforms like FaceTime and WhatsApp will let you call internationally at no charge and don’t require a lot of setup or investment. You can only call people with those apps, though, so make sure everyone has them downloaded before committing to this solution.
If you’re a business looking to set up a VoIP system with international calling capabilities, that’s another story. Platforms like Google Voice and Vonage are better set up for this, with clear rates and packages that can get you calling internationally today, for a monthly fee, of course. Plus, you’ll be able to call anyone with a phone using these services, so they’re more geared towards business functionality.
