Make a free call via your browser in Singapore

In short

To make a free call via your browser in Singapore, open Intercalling, allow the microphone, type the number with the plus sign and the country code, and tap call. The first call is free with no card. There is no app, no SIM and no exit code. After that, you pay only per minute.

Call from the browser, no app and no SIM

You do not need a SIM or an app to make a call. Intercalling uses your internet connection and your device microphone to place a real call on the normal phone network, reaching any landline or mobile worldwide. It is a real phone call, not a chat between two apps, so the person you reach answers their ordinary phone the way they always do.

Everything runs in the browser. Open Chrome, Safari, Edge or Firefox, allow microphone access, and type the number with the plus sign and country code. The call connects in a few seconds with clear voice, on your phone or computer. There is nothing to download, nothing to update and nothing taking up space on your device.

How browser calling works under the hood

The call uses WebRTC, the voice technology built into modern browsers. Your microphone audio travels over your internet connection to Intercalling, which then hands the call to the ordinary telephone network so it rings a normal phone on the other end. The handover is invisible to you, and the result feels like any other call.

This is why nothing needs installing and why the person you reach needs no app. They simply answer a ringing phone, whether it is a mobile or a landline. It also means there is no roaming, since the call rides your internet connection rather than a mobile network, so it works the same whether you are at home in Singapore or away on a trip.

Which browsers and devices work

Intercalling works in Chrome, Safari, Edge and Firefox, on both desktop and mobile. You can start a call from a laptop with no phone at all, or from a mobile browser without using your mobile minutes. The same account works across all of them, so you sign in once and call from whichever device is nearest.

The one thing to allow is microphone access when the browser asks, since the call uses your device audio. A stable wifi or mobile data connection keeps the voice clear, and you can switch between your laptop and phone without any extra setup. If the line ever sounds rough, it is almost always the internet connection rather than the call itself, so moving closer to the router usually fixes it.

How the free first call works

Every new account gets one free call to test the voice quality, with no card required. It is the fastest way to confirm the sound is good before you add any credit.

After the free call, billing is per minute with no monthly plan. You add a small amount of credit, which never expires, plus a small $0.004 connection fee per call. For example, a call to the USA is about $0.046 per minute.

Why a browser call beats a regular overseas call

On a normal Singapore line, overseas calls need the exit code 000 or 001 and run at higher international rates, sometimes with a daily access fee on top. In the browser you skip the exit code and pay a clear per minute price instead, with the rate shown before you dial.

Because the call goes over the internet, there is no roaming charge, even when you travel. The person you reach needs no app, no SIM and no account, so they answer like any other call. That makes it easy to reach someone who has never heard of Intercalling, since nothing changes on their side.
