1. OneSimCard General Service Questions
    • What is the difference between OneSimCard Plus, OneSimCard Data & Roam and OneSimCard Europe & More SIM cards?

      All 3 OneSimCard SIMs work in a very similar manner.  They all use an Estonian Mobile Number as the primary number and offer a Free US or Canada PEN for 30 days. All OneSimCards also offer many  additional features such as Global Concierge, 24/7 Live Technical Support, SIM VOIP and Apps for iPhone and Android.

      The main difference between the 3 SIM cards is that OneSimCard Plus offers Voice and SMS Text Messaging in many more countries.  The OneSimCard Data & Roam is recommended mostly for Internet Data on iPads, Smart Phones, Mi-FI devices and generally offers lower Internet Data Rates and Data Services in many more countries .  For some countries like Canada, Cuba, Brazil and a few others, the OneSimCard Data & Roam offers lower calling rates. 

      The OneSimCard Europe & More was specially created for European travelers and offers our best calling rates to the US & Canada,  from the 40 included countries, all with easy Direct Dialing, while OneSimCard Plus and OneSimCard Data & Roam utilize callback.

      OneSimCard Plus, OneSimCard Data & Roam and OneSimCard Europe & More also operate on different networks in many countries.

      You can compare rates for all these SIM cards here.

2. How To Use Questions
    • Is there any way to remove the callback ring after I dial a number?

      The newly offered OneSimCard Europe & More does not use the callback to make an outgoing call.

       

      With OneSimCard Plus or Data & Roam SIM:

      Normally, when you make a call with OneSimCard the phone will ring back within a few seconds after dialing and you will then get connected. You can eliminate this callback if you have a smarphone running Android (OS version 5 or below) by downloading and installing our OneSimCard Direct mobile app. Alternatively, you can purchase our Global Dual SIM Quad-Band GSM Unlocked International Cell Phone which has built-in software that automatically removes the callback.

      For phones using Android (OS version 5 or below):

      OneSimCard Direct allows you to hide the callback and makes it easier to make a call directly from your phone's address book.

      Once the application is installed on your phone, please run it once and then turn your phone off and back on. You will then be able to dial without receiving the callback.
3. How To Use Questions
    • There is no OneSimCard Menu (SIM Toolkit) in my Android phone. How can I fix this?

      Some recent Android upgrades to versions 4.2.1 and 4.2.2 have a bug causing the OneSimCard Menu, labeled as SIM Toolkit, to be disabled.

      If you do not see the SIM Toolkit app in your Android phone, please try doing the following:

      Go to Settings>Security>Setup SIM Card Lock>Lock SIM Card. It will ask for the default SIM PIN. Enter 0000. Power off the phone and turn it back on. The SIM Toolkit app will then become available, though it might take 1-2 minutes for the phone to display it.

      On Android version 5.1 go to Settings > SIM Cards > SIM Toolkit

      Once you have access to the SIM Toolkit, select it, scroll down to Settings, enter 1101 and press confirm. Your phone will now be able to dial normally.

4. How To Use Questions
    • How Do I Check The Balance Of Purchased Data Package?

      There are three ways to check the remaining balance of purchased data package.

       

      1. On-line in OneSimCard Menu of your account in the Discount Section of the page.

      2. On Android Phones - from OneSimCard Direct App and on Apple devices from OneSimCard Assist app

      3. From OneSimCard mobile phone: 

                                              Dial the following:

      *146*942#

       

      The remaining data balance will be displayed.

5. Troubleshooting Questions
    • When I try to make a call, I get a message 'Call is modified and cannot be made'. What does that mean?

      Some phone models do not allow direct dialing with older OneSimCard SIMs sold before January 1, 2017.

      To get around this problem, you should try either of these methods:
      • Locate the OneSimCard menu on your phone. (Some phones have it in Applications.)
        Make a call using menu 'Call'.
      • You can also make a call by dialing directly *146*00 Country Code Number#
        For example, to make a call to the USA, you would dial *146*0018574440686# (do not forget to hit pound at the end of the number)
      * is a star character located on the keypad
      Other examples of how to use th *146* dialing prefix if necessary:
      • To check your balance dial  *146*099# and press the TALK (or SEND) button
      • To add funds dial *146*098XXXX*ZZ# and press the TALK (or SEND) button,
        where XXXX - 4 last digit of your credit card on file, ZZ - Recharge amount
      • You need to press * on your phone in the above dialing sequences (it is a star character located on the keypad)
      • Activation of voice mail *146*091# and press the TALK (or SEND) button
      • Deactivation of voice mail *146*090# and press the TALK (or SEND) button
      • Check number of messages in Voice Mail *146*094# and press the TALK (or SEND) button
      • To listen to voice mail *146*095# and press the TALK (or SEND) button

      The prefix *146* and # at the end can be used from any phone. However, newer OneSimCard SIM do not require it and you should be able to dial codes directly, 091, 094, 095, 099 or 098XXXX*XX Talk.

      If you have an older SIM and the dialing does not work without entering *146*, please follow these simple instructions to remove the need to dial *146*:

      How to activate compatibility mode:

      1. Locate OneSimCard Menu.

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

               On Androids it is called SIM Toolkit app and it looks like one of the apps

      1. Open "OneSimCard" menu ( SIM Applications, SIM Toolkit, STK)
      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.

      When dialed directly, some Nokia and other phones can display message: "Call is not allowed" or "Call is barred". Just ignore this message and wait for the ring-back for 10 seconds or so.


      If your phone is built on Android, you can download an application that will remove the callback ring completely (Android OS version 5 or below) called OneSimCard Direct from Google Play.
6. Troubleshooting Questions
    • When I dial following your instructions it does not work. What's wrong?

      This answer applies to SIM cards purchased before January 1, 2017.

      Some phones, such as Samsung, some Motorola, Android and Apple iPhones, require special dialing instructions or simple OneSimCard settings menu changes in order to make calls.

      It is possible to make almost any phone entirely compatible, so you can call directly without using the OneSimCard menu or *146* by following these simple programming instructions below.

      How to activate compatibility mode:

        1. Locate OneSimCard Menu.

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

               On Androids it is called SIM Toolkit app or OneSimCard app and it looks like one of the apps.

         

      1. Open "OneSimCard" menu ( SIM Applications, SIM Toolkit, STK)
      2. Select "Settings
        Newer SIM Cards: Select Service Code option and follow instructions below:
        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.

          If for any reason after entering compatibily code, you still do not get a ringback or you get the ringback the first time you make a call, but second time it would not work, please enter code 802 into the Service Code window instead of 1101 as provided above.

           

          Please bear in mind that Android phones can use OneSimCard Direct App available free for download from Google Play.  Using this app takes care of the Android phones compatibility issues, allows to remove the callback ring (Android OS version 5 or below) and also will automatically correct mis-dialed phone calls in most cases. iPhone users can download OneSimCard Assist App from iTunes that will do the same, except for removing the ringback.


          For example, calling to USA: Dial *146*0016175551212# and press the TALK (or SEND) button

          * is a star character located on the keypad
          • To check your balance dial  *146*099# and press the TALK (or SEND) button
          • To add funds dial *146*098XXXX*ZZ# and press the TALK (or SEND) button,
            where XXXX - 4 last digit of your credit card on file, ZZ - Recharge amount
          • You need to press * on your phone in the above dialing sequences
          • Activation of voice mail *146*091# and press the TALK (or SEND) button
          • Deactivation of voice mail *146*090# and press the TALK (or SEND) button
          • Check number of messages in Voice Mail *146*094# and press the TALK (or SEND) button
          • To listen to voice mail *146*095# and press the TALK (or SEND) button

          The sequence *146* and # at the end can be used from any phone. However, most phones do not require it.

          We strongly recommend you to watch very short video tutorials that will help you to understand how to make calls, SMS and data on your OneSimCard Phone.


          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 troubleshooting advice might be needed only for older SIM cards.

      9. OneSimCard General Service Questions
        • Which phones are compatible with OneSimCard service?

          Any unlocked GSM phone is compatible with OneSimCard Europe & More SIM that does not require any special dialing instructions.
          For Plus and Data & Roam SIM cards, most GSM unlocked Tri-band or Quad-Band phones are compatible with OneSimCard service.

          Older Verizon & Sprint dual-mode CDMA/GSM "World Phones" such as BlackBerry (Bold, Curve, Tour, Pearl, Storm, 8830); LG (Fathom); HTC (Touch, Ozone, Imagio); Samsung (Saga, Intrepid, Renown), are compatible with OneSimCard, however require special dialing instructions shown here.

           

          All iPhone modes and Androids GSM Phones are compatible with OneSimCard.

          Some phones will allow calling only from OneSimCard menu. Some phones will allow calling directly, but with the use of prefix *146* as described in the user guide.

          Some phones such as Samsung and some other brands require dialing a specific prefix *146* in front of the dialed string when used with a OneSimCard.

          For example, calling to USA: Dial *146*0016175551212# and press the TALK (or SEND) button
          * is a star character located on the keypad
          • To check your balance dial *146*099 and press the TALK (or SEND) button
          • To add funds dial *146*098XXXX*ZZ and press the TALK (or SEND) button,

      10. OneSimCard General Service Questions
        • What Is the Difference Between "Direct Dial" and "Callback Dial" calling?

          Direct Dial calling allows the caller to enter the international  call prefix, country calling code and telephone number and then be directly connected to the person they are calling. This is how you dial when using your regular mobile service. Direct Dial Calling is standard on the OneSimCard Europe & More.

          Callback calling also allows the caller to enter the international  call prefix, country calling code and telephone number. After the called number is entered, the user immediately receives an incoming call connecting the user to person called. Callback is very simple to use and allows for low cost calling on the OneSimCard Plus and OneSimCard Data & Roam. Callback does not increase the connection time. It is the same as with Direct Dial. Usage of the OneSimCard Direct mobile app hides the callback.
