    • When making an outgoing call how do I select which way the call should go: through regular roaming or through OneSim VoIP?

      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 from your regular phone dial pad.

    • What is required to use the OneSim VoIP mobile application?

      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.

    • What are the advantages of using OneSim VoIP?

      The main advantages are significant cost savings and the ability to call from countries where there is no roaming coverage available.
      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/4G - 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.
      OneSim VoIP is available with the following SIM cards: Plus, Expedition (formerly Data & Roam) and Europe & More.

    • Is it free for someone to call my OneSimCard number using Viber?

      Through a unique partnership with Viber, your primary OneSimCard number (+372) can be called free of charge for any Viber user! (requires activation and special dialing instructions, see below)

      HOW: When this feature is activated, Viber users can call OneSimCard numbers for free by using a special dialing format +372800XXXXXXXX, where XXXXXXXX is the rest of the OneSimCard phone number after 372. For example, a OneSimCard user with the phone number +37212345678 should be called by dialing +37280012345678.

      TO ACTIVATE: Log in to your OneSimCard account and go to the My SIM Cards menu. Scroll down to where it says "Incoming Viber Calls" and click Enable to activate this option.

      COST: The call is free for the Viber user. The cost of receiving the Viber call is the same as receiving a call through a Personal Extra Number (PEN), i.e. the regular incoming call rate in the country you are in plus 20c/min. In countries with free incoming calls, like Italy or Japan, the cost will be just 20c/min.

      PLEASE NOTE:

      • When dialing in Viber, if Viber user chooses the Estonian country code in the menu then they should just dial 800XXXXXXXX because the +372 is added automatically.
      • If the “free calls to OneSimCard from Viber” option is not activated for a particular OneSimCard number, when a Viber user dials +372800XXXXXXXX they will hear an automatic message: “The mobile phone is either switched off or out of coverage area.”
