51. OneSim VoIP

    • I can make calls through OneSim VoIP. However incoming calls are going through my roaming SIM. What's wrong?

      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.

    • I have more than one Personal Extra Number (PEN). Can I use different PENs for OneSim VoIP?

      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.
53. 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.

    • How does OneSim VoIP work when the call is received?

      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.
55. Ordering Questions

    • Do I need to activate the SIM card when my order is received or purchased from a retail store?

      Yes, you will need to activate the SIM card once the order is received.

      All OneSimCard international SIM cards and international cell phones with SIM cards are shipped inactive to prevent theft and improve security. Only the person who placed the order for OneSimCard service can activate it.

      Activation is very simple: When you receive the SIM, just log in to your account at www.OneSimCard.com and click the large Activate button you will see in the middle of the screen.

      Retail Customers: If you purchased your SIM card through an online or brick-and-mortar retail store, you should have received activation instructions inside the product packaging. To activate retail SIM cards, go to www.OneSimCard.com/Retail enter your new OneSimCard international mobile number and fill out the form to register and activate the SIM card. You will be provided specific instructions on the registration page.

    • 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.

59. Ordering Questions

    • How do I order Discount Call, Text and Data plans?

      You can order discount Call, Text and Data packages from your OneSimCard web account after you have received and activated your OneSimCard. 

      NOTE: for DataMax and DataMax eSIM, there are no call or text messaging discount package, since these are already deeply discounted through the 1SIM VoIP App.

      To order a discount package for your SIM card, follow these steps:

      1. Log into your account at OneSimCard.com
      2. Click on the My SIM Cards menu links
      3. If you have more than one SIM card, make sure the SIM Card you’d like to activate a discount package for is selected
      4. Navigate to the Discount Service Plans section and select a discount package you would like to activate
      5. Click Activate Now to activate the selected package immediately or Activate Later to schedule the activation on a particular date.

       

      Future data plan activation:

      a. You can set up the maximum number of times data packages to be activated automatically when the package is used up or expired.

      b. You can set the date after which no packages will be activated, so when your travel is over no data packages will be activated and no charges will follow.

      Note: eSIM World data plan activation may vary from regular Universal or Expedition SIM cards. Please follow directions on the account page.

      To learn more about the availability of discount packages for different SIM cards and countries, please visit the Rates & Coverage page.

       
60. Troubleshooting Questions

    • I have an Apple iPhone. When I dial following your instructions it does not work. What's wrong?

      This reply does not apply to OneSimCard Europe & More SIM or newer SIM cards purchased after January 2017.
      Older SIM cards might require entering the compatibility code on your  iPhone.

      How to activate compatibility mode:

       1. Locate OneSimCard Menu.

       On iPhones it is called SIM Applications menu and is located under Settings- Phone menu

      1. Open "OneSimCard" menu ( SIM Applications)
      2. Select "Settings
      Newer SIM Cards: Select Compatibility option and make sure "On" is selected
      Older SIM Cards: After selecting Settings:
      1. Agree with message by pressing "Yes"
      2. Dial digits "1101" and select "OK" (Screen will show "CC OptionX: ON" message)

      Bear in mind that if you have powered your telephone down, and have removed and reinstalled the battery, you will need to follow the programming steps outlined above, again.


      We strongly recommend you to watch very short video tutorials for iPhone that will help you to understand how to make calls, SMS and data on your OneSimCard iPhone.
      If your phone is not Jail-Broken, you still can use OneSimCard Assist app available from iTunes. This app will help you to dial numbers properly by correcting mis-dialed numbers and will allow easy access to OneSimCard functions like checking balance, recharging your SIM, activating discounts and others.

      These videos are available in the Help Menu of your OneSimCard Portal. You need to log in to your OneSimCard account first and then proceed to the Help Menu to be able to access these videos.

      Again, this is for older SIM Cards. Newer SIM cards do not require entering any codes in iPhone or other types of phones.
