The best VoIP services for international calling

Skype Credit
From 1-5¢/min
Google Voice
Per-minute rates
Rebtel Unlimited
From $7.99/mo
Calling internationally over a US cellular plan typically costs 25 cents to $1.99 per minute. Calling the same numbers through a VoIP service typically costs 1-5 cents per minute - a 90+ percent reduction. For anyone who calls family abroad, conducts international business, or routinely calls international friends, switching to VoIP for those calls pays back immediately.
Best for personal use
Skype Credit
Skype's pay-as-you-go credit lets you call any phone number worldwide at competitive per-minute rates: 2.3 cents to Mexico, 3.5 cents to India, 1.7 cents to UK landlines. No subscription. Credit starts at $10 and rolls over indefinitely.
Skype is owned by Microsoft and works on iOS, Android, Windows, Mac, and web. The interface is familiar. Call quality depends on internet stability but is generally good.
Google Voice
Google Voice charges per-minute rates similar to Skype: 1 cent to Canada and Mexico (calls from the US), 1 cent to UK landlines, 5 cents to India, 4 cents to Philippines. The free version requires call origination from the Google Voice app or web.
For a US user wanting to make occasional international calls, Google Voice is often the simplest option since most people already have a Google account.
Rebtel: unlimited per country
Rebtel offers unlimited monthly subscriptions for specific countries - $9.99/month for unlimited calls to Mexico, $14.99 for India, $7.99 for the Philippines. For heavy callers to a single country, the unlimited plan is cheaper than per-minute pricing.
Best for business
RingCentral Standard
RingCentral business plans include domestic unlimited calling and international rates that are typically 30-50% lower than typical cellular international rates. For businesses making regular calls to specific international markets, RingCentral's rate sheet is competitive.
For a small business with regular international clients, the right setup is often a domestic VoIP plan (RingCentral or Nextiva) plus international calling enabled on a per-minute basis.
Vonage Business International
Vonage offers business international calling plans with specific country bundles. For a business calling regularly to Mexico, the UK, or India, the bundled plans are cost-effective.
What affects international call quality
Your internet connection quality matters more than the service. A stable 10 Mbps connection delivers excellent VoIP calls. A flaky 50 Mbps connection delivers terrible ones.
The destination country's infrastructure also matters. Calls to landlines in developed countries are typically clearer than calls to mobile phones in countries with congested cellular networks. This is not a fault of the VoIP service - it is the last-mile connection.
Alternatives
WhatsApp Voice and FaceTime Audio offer free calls between users of the same service. For staying in touch with family abroad who also have smartphones, persuading them to install WhatsApp eliminates the cost question entirely. Most international family communication has shifted to this model.
Per-day international roaming through your US cellular plan (Verizon TravelPass, AT&T International Day Pass) makes sense for short trips abroad where convenience outweighs cost. For sustained international calling from the US, VoIP is dramatically cheaper.
