Tired of paying high phone bills every time you need to make free international calls?
You might be surprised that many international calls can be made for free.
It really hit me during a work trip abroad. I made a quick call home, only to discover later that the roaming charge cost more than my hotel breakfast. That experience led me to test dozens of apps to make international calls to find which ones actually work, and which ones quietly charge you when you least expect it.
I also found that “free” doesn’t always mean completely free. Most apps fall into one of these categories:
- Free app-to-app calls over the internet
- Freemium apps with limited free credits
- Paid plans for calling landlines or mobile numbers
- Regional restrictions that limit availability
