1. eSIM
    • Do you offer eSIM option for iPhones and Androids?

      Yes. OneSimCard now offers an eSIM option.


      eSIM is not a physical SIM, but rather a program that can be downloaded to compatible with eSIM phones. As of December 5, 2019 such phones are iPhone XS, iPhone XS Max, iPhone XR, Iphone 11, Google Pixel 3a and Pixel 4.


       Note: iPhone XS and XR manufactured for the Chinese Market have 2 physical SIM card slots and are not eSIM capable. Pixel 3a can't use eSIM if the phone was purchased in Japan, or if bought with Verizon or Charter service.
2. OneSimCard General Service Questions
    • What is the difference between eSIM, OneSimCard Universal, OneSimCard Expedition (formerly Data & Roam) and OneSimCard Europe & More SIM cards?

      All 4 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 24/7 Live Technical Support, SIM VOIP and Apps for iPhone and Android.

      The main difference between the 4 SIM cards is that OneSimCard Universal and eSIM offers Voice and SMS Text Messaging in many more countries as well as lower data rates.  The OneSimCard Expedition (formerly Data & Roam) is recommended to be used in some countries where for it offers coverage while Universal SIM does not.  For some countries like Canada, Cuba, Brazil and a few others, the OneSimCard Expedition (formerly 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. Both the Europe, eSIM and Universal SIM cards offer easy Direct Dialing in 40 (EM) and 75 countries respectively, while OneSimCard Expedition (formerly Data & Roam) utilizes callback. eSIM and Universal SIM offers callback dialing in those 130 countries which are not covered by the Direct Dialing. Callback dialing does not make it more complex for the caller, except for pressing the Talk button on the mobile phone twice instead of once when making a call.

      OneSimCard Universal, Plus, OneSimCard Expedition (formerly Data & Roam) and OneSimCard Europe & More also operate on different networks in many countries.

      You can compare rates for all these SIM cards here.

3. 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.

           

          iPhone users can download OneSimCard Assist App from iTunes that will takes care of the iphones compatibility issues, 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.

           

           

      4. 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.

      5. 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, OneSimCard Universal and eSIM.

          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 Expedition (formerly Data & Roam). Callback does not increase the connection time. It is the same as with Direct Dial.

      6. 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.

      7. OneSimCard General Service Questions
        • What Are Additional Calling Options Available?

          There are many additional options available to reduce cost as well as to make it easier for callers to reach OneSimCard phone.

      8. 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,
            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

      9. Troubleshooting Questions
        • I have a OneSimCard SIM and my phone will not register on a roaming network, what's wrong?

          Sometimes when moving from the USA, Canada or Mexico to another country, the SIM card will need to be reset to properly register on a new country roaming network.

          • If you have the OneSimCard Menu on your phone (it may be called Sim Application Menu on iPhones or SIM Toolkit on Androids), go to the menu, scroll down to Settings and enter Service Code 2003 and confirm, then Code 000 and confirm. For older SIM cards after this enter Service Code 1101 and confirm. Turn the phone off and then back on. 

          • If you do not have access to the OneSimCard Menu then turn off your phone, remove the battery for 20 seconds, reinstall the battery and then turn back on your phone.
      10. OneSimCard Rentals
