How to call overseas without a SIM from Australia

In short

To call overseas without a SIM from Australia, use StartACall in your browser. It places real calls over wifi or data using your device microphone, with no SIM card, no app and no number of your own. The first call is free, then you simply pay by the minute with credit that never expires.

Call using only wifi or data

You do not need a SIM card to make a call. StartACall uses your internet connection and your device microphone to place a real call onto the ordinary phone network, reaching any landline or mobile in the world.

That is handy when your SIM has no signal, no international allowance, or when you are on a computer with no phone at all. Because the call travels over the internet, there is no roaming charge to worry about while you are away from home.

Nothing to download

Everything happens in the browser. There is no app to install and no update to run. Open Chrome, Safari, Edge or Firefox, allow microphone access when prompted, then type the number with its country code.

The first call is free so you can test it. After that, billing is by the minute with no monthly plan and a small $0.004 connection fee, and the credit you top up never expires. The person you ring needs no app and no account of their own.

Because the dialler lives in the browser, there is also nothing to keep updated. An app can stop working after a phone update or quietly drain your battery in the background, but a browser tab only runs while you are on a call, then closes when you are done.

Why this beats a travel SIM for quick calls

A travel SIM means swapping cards, topping up a separate balance and often paying for an allowance you never finish. With StartACall there is none of that. You keep your usual setup and just open a browser tab when you want to call.

From a number like +91 for India, +84 for Vietnam or +44 for the UK, you dial the plus sign, the country code, then the number without its leading zero. The same browser works whether you are at home in Australia or travelling abroad.

A travel SIM also locks you to one device and one phone number, whereas a browser tab follows you across a laptop, a tablet and a phone. Sign in on whichever device is to hand, allow the microphone, and your credit and call history are right there, with no card to move between handsets.

When calling without a SIM helps most

Travellers often land somewhere with no working SIM until they buy a local one, yet still need to make a call straight away. A laptop or tablet on hotel or airport wifi can place that call through the browser before you have sorted out any local number.

It also suits anyone whose phone is between plans, waiting on a replacement SIM, or simply out of international credit. Because the browser route only depends on an internet connection, it works as a reliable backup any time your normal line is not available, including on a spare device that has never had a SIM at all.

A worked example, step by step

Say you want to ring a mobile in the UK written locally as 07700 900000. Open StartACall, allow the microphone, then type +44 7700 900000, dropping the leading zero from the 07. Press call and the browser connects straight to that UK mobile over your internet connection.

The same three steps work for any country. Type the plus sign, the country code, then the number with its local leading zero removed. There is no exit code to remember and no SIM in the loop, so the call behaves exactly like a normal phone call once the other person answers.

On a normal Australian phone you would otherwise start with the exit code 0011 before the country code, but the browser handles that part for you. That is one less thing to get wrong, and it is the same whether you are dialling India on +91, Vietnam on +84 or the UK on +44.
