    • Is there an eSIM App for Apple iOS and Android devices?

      Yes. The 1Sim eSIM app is available at:

      Get it on Google Play



      These apps allow for much easier management of eSIM data plans.

      To connect your eSIM app to your existing web account at www.onesimcard.com, please complete the following simple steps:

      1. Install eSIM app

      2. Log in to the eSIM app using email and password for your current online OneSimCard account

      That is all. You will be able to see the device connected to your web account in the MY SIM Cards menu of your account at www.OneSimCard.com

      Customers who ordered an eSIM directly from the eSIM app do not need to connect the app and their online account at OneSimCard.com as they are already connected.

16. Rates and Cost Questions
    • 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.

17. Rates and Cost Questions
    • What is the cost to make calls from a OneSimCard phone to another OneSimCard phone?

      It depends on the country you're in when making the call. In many countries there is a special low rate of just $0.25/min to call another OneSimCard phone (only when dialing the other OneSimCard user's primary mobile number, not a Personal Extra Number). In other countries your cost will be our standard low outgoing call rate from that country.

      Example: two OneSimCard users are in Italy and one calls the other, the cost will be $0.25/min for the caller and free for the receiver.

      Visit our Rates & Coverage page and choose any country to view its current rates. Use the dropdown menus to see rates for calling to/from other countries.

      PLEASE NOTE: If you activate a discount call plan, the special rate to make OneSimCard-to-OneSimCard calls will not be available. You will be charged for those calls according to the discount call plan rate. 

      Another great benefit of using OneSim VoIP: To call using the 1SIM VoIP App to another user on the 1SIM VoIP App, this call is free, so long as you are calling the PEN associated with their 1SIM VoIP App.

       

18. Troubleshooting Questions
    • Does iPhone Hotspot work with OneSimCard?

      Yes. All unlocked iPhones' Hotspot feature works with OneSimCard SIM.

       
      There are a few settings to make sure for this to function properly on your iPhone:
      1. Settings - Cellular - Cellular Data - ON
      2. Settings - Cellular - Data Roaming - ON
      3. Settings - Cellular - Cellular Data Network - Cellular Data - APN = APN will be set automatically
      4. Settings - Wi-Fi - ON
      5. Settings - Personal Hotspot - ON. 
      After turning the Hotspot on, you should stay on the Personal Hotspot screen of your iPhone for SSID of your phone to show up on other Wi-Fi devices, so you can get connected. After you connected to the Hotspot, you can leave the screen. Alternatively, you can always use Bluetooth or USB connection to provide the internet access from your OneSimCard iPhone Hotspot to your other devices.
19. OneSim VoIP
    • 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. 

      NOTE: Regular roaming calling is NOT available on DataMax or DataMax eSIM cards. To use voice you will need to use the OneSim VoIP app

20. OneSim VoIP
    • Where can I find the settings required to be entered into the OneSim VoIP app?

      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.
