    • 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.

62. eSIM
    • What is an eSIM & how does it work?

      eSIM is not a physical SIM. It is a piece of software downloaded to a compatible phone. So there is no shipping involved with delivering eSIM.


      eSIM makes your iPhone or Android phone to be a dual SIM phone. This means that you can use two sim cards on the phone at the same time. You can select which SIM card is used for calls and texts, and which one is used for data. You can select which sim card is to be the primary and which one not to be used. You can make these changes from the settings of your phone at any time. In short - eSIM offers greater flexibility to your eSIM compatible phone. It allows you to use the service provider of your choice - whether you are traveling or staying home.


      OneSimCard eSIM can be installed only on a single device. It can't be moved to another device, but it can be re-installed on the original device up to 3 times if required.
63. OneSim VoIP
    • 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.

    • Is there a way to send a SMS to a short code number?

      The SIM card does not offer SMS service to short code numbers

      OneSimCard offers special US Phone Numbers working with the SIM or even without SIM which are capable of receiving SMS from Short Codes, like those sent by Banks, Paypal and other institutions as well as replying to short codes SMS using 1SIM VOIP app.
