When you call without SIM, you're making phone calls using internet-based technology instead of traditional cellular networks. This means you don't need a physical SIM card, active mobile service, or carrier plan. Your device connects to the internet (via WiFi or ethernet), and your voice travels over the web to reach any phone number worldwide. The person you're calling receives a normal phone call on their landline or mobile - they don't need internet or any special app. This works from any device with an internet connection.

To call someone without a SIM card, open HelloAirDial in your browser, enter their phone number with country code, and click Call. Your voice is sent over the internet and connected to the regular phone network so they receive a normal call. The technology (WebRTC) works from any device with internet access: laptops, tablets, smartphones, or phones on WiFi. Learn more about how browser calling works.
