Google Voice: Free US Calls, Limited Internationally
Google Voice is a solid free option if you live in the US and primarily call US and Canada numbers. International rates exist but aren't competitive — popular destinations like India mobile and Philippines mobile cost significantly more than dedicated international calling services.
The biggest limitation: you need a US phone number to sign up, and virtual numbers are only available in the US. If you're outside the US or need to show local numbers in other countries, Google Voice can't help.
Skype Is Dead — Long Live... Teams?
Microsoft shut down Skype in May 2025 and pushed users to Teams. While Teams technically supports PSTN calling, it's designed for enterprise video meetings, not cheap international calls. The interface is cluttered, pricing requires a Microsoft 365 subscription plus a calling plan, and the entire experience feels like using a firehose to water a plant.
If you're a business already paying for Microsoft 365, Teams calling might make sense. For everyone else, it's overkill.
