    • Is there a 911 emergency number in Europe that can be used with OneSimCard service?

      Yes, in Europe the emergency number is 112. You can use 112 in Europe to report real emergencies to local authorities in the country of stay. The 3 digit number should be dialed directly without any additional digits in front of the number.

       

      For DataMax and DataMax eSIM SIM cards, while there is no voice calling feature without the use of 1SIM VoIP, which doesn’t support emergency calling, most cell phones ALWAYS allow you to call emergency numbers, even without a SIM inserted into the phone. In Europe the emergency number is 112. You can use 112 in Europe to report real emergencies to local authorities in the country of stay. The 3 digit number should be dialed directly using the regular phone app (NOT the OneSim VoIP App) without any additional digits in front of the number.

    • 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 8 or higher, or Apple device (iPhone, iPad, 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. NB: YOU MUST create the 1SIM VoIP account in your account online on the "My SIM Cards" menu. Simply purchasing a PEN and  downloading the mobile app DOES NOT create the VoIP account.

104. OneSim VoIP
    • When I make a call using OneSim VoIP the quality of the call is not as good as the quality of the regular roaming connection. Can this be improved?

      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.

109. How To Use Questions
    • How do I make a call within the country I am currently located?

      You should make any call the same way as if you were making an international call.

      For example, you are in France and need to call Paris:
      You should dial 00331XXXXXXXX. Please note that you should not dial 01 for Paris, but rather just 1 after country code 33, because Paris' code is 1.

      Dialing 0 in front of 1 is required when making a regular long distance call within France to Paris. However, when making an international call or OneSimCard call, 0 is omitted.

      For example, if you are located in Italy and need to call Rome:
      You should dial 003906XXXXXXXX, as Rome's code is 06.
