Yes, you can make calls without a SIM card using VoIP apps. The best option is BubblyPhone which works directly in your browser - no app installation or SIM required. Other options include WhatsApp, Skype, and Google Voice (US only).
How Does Calling Without a SIM Card Work?
When you make a traditional phone call, your phone uses the cellular network through your SIM card. But with VoIP (Voice over Internet Protocol) technology, your voice is converted into data packets and transmitted over the internet instead. This means you only need:
- WiFi connection - Home, office, cafe, or hotel WiFi
- Mobile data - Even without a SIM, some devices support WiFi calling or eSIM data plans
- A VoIP app or service - Like BubblyPhone, WhatsApp, or Skype
VoIP calling can save you up to 95% compared to traditional international calls. A 10-minute call to India costs just $0.10 with BubblyPhone vs $10+ with most carriers.
