Google Voice is a solid calling service — if you live in the United States. For the rest of the world, it's either unavailable or severely limited. If you've searched for "Google Voice" in Germany, the UK, Australia, or most other countries, you've probably hit the same wall: "Google Voice is not available in your country."
This guide covers the best Google Voice alternatives that actually work for international calls from anywhere in the world — no US phone number required, no geographic restrictions.
Why Google Voice Doesn't Work for Most People
Google Voice has three major limitations that push people toward alternatives:
It's US-only. Google Voice requires a US phone number to sign up and is officially available only in the United States. If you're in Germany, the UK, Australia, France, Spain, Italy, or anywhere outside the US, you can't create a Google Voice account through normal means.
International calls aren't free. Even for US-based users, Google Voice only offers free calls to US and Canadian numbers. Calling any other country costs per minute, and the rates aren't always competitive.
It requires phone verification. You need an existing US phone number to verify your account. If you're abroad, traveling without a US SIM, or simply don't have a US number, you're locked out.
If any of these apply to you, here are the alternatives worth considering.
Best Google Voice Alternatives for International Calls

Calloza is a browser-based calling service that works from any country. No app downloads, no phone number required to sign up, no geographic restrictions.

Google Voice Availability by Country
If you're wondering whether Google Voice works in your specific country, here's the short answer — it almost certainly doesn't. Google Voice is officially available only in the US. Here's what that means for the most commonly searched countries:
Google Voice in Australia — Not available. You can't sign up for Google Voice from Australia or get an Australian number. For calling Australian numbers or calling from Australia internationally, a browser-based service like Calloza or Skype are your best options.
Google Voice in the UK — Not available. Google had a similar service called "Google Voice UK" years ago, but it was discontinued. British users need a third-party alternative for international calling.
Google Voice in Germany — Not available. German users looking for a VoIP calling solution need to use alternatives that operate globally. Browser-based services work without any regional restrictions.
Google Voice in France — Not available. Same situation as Germany — no official Google Voice support. Alternatives that require no phone verification are the simplest path.
Google Voice in Spain — Not available. Spanish users searching for cheap international calling are better served by pay-as-you-go browser-based services.
Google Voice in Italy — Not available. Italian users looking for an international calling solution should consider services that support calls to Italian numbers at competitive rates.
Google Voice in Mexico — Not available. For calling Mexico or calling from Mexico, prepaid browser-based calling typically offers the best rates.
Google Voice in Canada — Partially available. Google Voice works for making calls in Canada, but the feature set is limited compared to the US version. Canadian users who need broader international calling should consider alternatives.
What to Look For in a Google Voice Alternative
If you're switching from Google Voice (or never had access to it), here's what matters:
No geographic restrictions. The whole reason you're looking for an alternative is likely because Google Voice doesn't work in your country. Make sure the alternative works globally.
No phone number required to sign up. If you're abroad without a local SIM, services that require phone verification create a chicken-and-egg problem. Email-only signup is ideal.
Transparent per-minute pricing. Check the rates for the specific countries you'll be calling. Some services advertise "cheap rates" but charge premium prices for certain destinations.
Browser-based option. Not needing to install an app means you can make calls from any device — your laptop at a hotel, a borrowed tablet, or your phone on Wi-Fi. It also means no storage space wasted and no app permissions to worry about.
No subscription lock-in. If you call internationally occasionally rather than daily, pay-as-you-go is almost always cheaper than a monthly subscription.
The Bottom Line
Google Voice is great if you're in the US calling US numbers. For everything else — calling internationally, calling from outside the US, or calling without a US phone number — you need an alternative.
For the most flexibility with zero setup friction, browser-based calling services let you dial any number from any country without app downloads or phone verification. If you need unlimited calling to one specific country, a service like Rebtel may be cheaper. And if you're just calling other app users, WhatsApp and Viber are free.
The right choice depends on where you are, where you're calling, and how often. But if Google Voice won't work for you, there's no shortage of options that will.
