OneSim VoiP can be used from any Android or Apple ( iOS) device to make international LD calls even when you are not traveling. OneSim VoIP does not require having OneSimCard SIM being installed in the phone. OneSim VoIP can be used with Wi-Fi or 3G - no difference. You just need to have OneSimCard account with the SIM VoIP capable PEN. Calling using OneSim VoIP will cost most of the time less than any other way of calling including Skype.
OneSim VoIP is available with all 3 types of SIM card we offer - Plus, Data & Roam and Europe & More.
OneSimCard VoIP requires you to order a compatible Personal Extra Number (PEN). Most of the PENs we offer are OneSim VoIP enabled. You also need to have an Android phone with software version 4.2 or higher, or Apple device (iPhone, iPaed, iPod Touch) with iOS 6.1 or higher.
Once you have an active OneSim VoIP enabled PEN, you will be able to see the option to create a OneSim VoIP account in the My SIM Cards menu of your online account.
There is no additional cost except for the fact that you need to have a compatible Personal Extra Number (PEN) active on your SIM card.
Once you create the OneSim VoIP account, you will be emailed settings and instructions. You can also see the settings in the My SIM Cards menu of your online account.
To make an outgoing call using OneSim VoIP, you need to be registered on a Wi-Fi network and have the OneSim VoIP app running on your phone. You should make the call using the OneSim VoIP app dial pad. To make a call the regular roaming way, you should make a call using the OneSimCard Direct app or from your regular phone dial pad.
When someone dials your OneSim VoIP enabled Personal Extra Number (PEN), the system will first check if your OneSimCard phone is registered with the OneSim VoIP app on a Wi-Fi network. If it is registered, the call will be sent using VoIP. If the OneSim VoIP app is not running or it is not registered on a Wi-Fi network, then the call will be sent using the standard OneSimCard roaming network and charged our standard roaming rates.
Yes. If you are not available to answer the OneSim VoIP call or if the OneSim VoIP app is turned off, the call will be routed through our standard roaming network. If the call is not answered it will be sent to your OneSimCard voicemail box.
The quality of a OneSim VoIP call is only defined by the quality of your Wi-Fi connection. This is the part of the connection that we can not control. Quality of the Wi-Fi connection is defined by many parameters, rather than just by the speed of the connection. With a good Wi-Fi connection the quality of the call will be similar to using our regular roaming network.

If you have more than one OneSim VoIP enabled PEN you can switch between these PENs for the purpose of the OneSim VoIP account. This option is available in the My SIM Cards menu in your online account.
Your active OneSim VoIP Personal Extra Number (PEN) will be shown on the caller ID.
If your incoming calls are not being routed through the OneSim VoIP app then you are either not connected to Wi-Fi or the OneSim VoIP app is not active.
Please make sure to check your phone's sleep settings, as they are usually preset to have Wi-Fi turn off when the phone enters sleep mode. To prevent this and to keep OneSim VoIP active for incoming calls, find the settings in your phone and set it so Wi-Fi does not turn off when the phone enters sleep mode.
Note: if the OneSim VoIP logo on the top of your phone display is gray then you will not be able to receive calls through the application. When the logo is yellow that means you are connected and can receive calls through OneSim VoIP.
In countries where the cost of using mobile Internet Data is below 20 c/MB, the cost of using SIM VoIP over the data is comparable or smaller than the actual calling rate from the country.
As a rule ot thumb, the SIM VoIP will use 1MB /Min of talk time. So if the cost of Data in the country is 10 c/MB, then 1 minute SIM VoIP call will cost you 12 cent /minute. You need to have a 3G connection in order for SIM VoIP to work this way.
OneSimCard SIM VoIP users with US and Canadian numbers may now send and receive text messages over the OneSim VoIP app on iPhone and Android. The cost to send or receive each message is $0.05.
