Our OneSim-VoIP application (available for Android 4.2 and higher and Apple iOS 6.1 or higher) lets you save even more money when a sufficient Wi-Fi connection is available.

What are the benefits of using OneSim VoIP?

There are two major benefits of OneSim-VoIP: coverage and rates.

In the few countries where we provide limited or no GSM coverage, as long as you can access a sufficient Wi-Fi connection then you will still be able to make and receive calls on your OneSimCard Personal Extra Number (PEN).

If you like OneSimCard's standard low GSM rates, then you'll love our OneSim-VoIP rates. No matter where you are in the world, it's just 1c/min to receive calls!* The outgoing call rate only depends on the phone number you are calling to - for example, calling to a continental U.S. or Canadian phone number is just 2c/min. Calls between two phones both using OneSim-VoIP are absolutely free! OneSim-VoIP rates for all countries can be viewed at our Rates and Coverage page by choosing any country.

* Cost for receiving calls through a Local PEN. It is 5c/min to receive calls through a Toll Free PEN.

How is making and receiving calls with OneSim-VoIP different from regular calls?

The main difference is the cost and call quality. Connection quality of the calls made using OneSim-VoIP option over Wi-Fi will only be as good as the quality of the Wi-Fi connection.

Please be advised that depending on the strength of your Wi-Fi connection, the quality of OneSim VoIP calls can be inferior to the connection quality of the regular OneSimCard international SIM card roaming network.
