1. 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.

2. 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 compatibility 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.

           

           

      3. Troubleshooting Questions
        • I have a Samsung phone. When I dial following your instructions it does not work. What's wrong?

          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
          • 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* can be used from any phone. However, most phones do not require it.

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

          How to activate compatibility mode:

            1. Locate and Open "OneSimCard" Menu. ( It could  be displayed as STK Menu)

                  2. Select "Settings"

            Newer SIM Cards: Select "Compatibility" 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.

          4. 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 Live Customer 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.

          5. 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.

               
              These options are:
              • PEN - Personal Extra Numbers - Provides an option to call OneSimCard phone directly locally from 60 countries.
              • CAN - Common Extra Numbers - Provides an option to call OneSimCard phone¬†locally from 10 countries without ordering a PEN. See Help Menu of your on-line account for details.
              • SIM VOIP - iPhone and Android App allows lower cost calling and texting over WI-FI or Mobile Data.
              • OneSimCard Connect App - Android App¬†Makes dialing easier. Auto-correct mis-dialed numbers. Removes the callback feature on the Plus and Expedition (formerly Data & Roam) SIM cards.
              • Viber - Allows Viber Callers to call free to OneSimCard Phone.
          6. How To Use Questions
            • How can I dial '+' on my phone when making call?

              Note: You can always dial 00 instead of + when making outgoing calls. For example, to reach OneSimCard customer service in the USA you can just dial 001 617 3138888.

              You should consult the phone manual for this info. Different manufacturers have specific ways to access the '+' key, so make sure you know yours.

              Here are few known ways:
              • BlackBerry?ģ 6210: Press Alt (bottom, far left on keyboard) and the letter "I".
              • Bosch: Press and hold the star (*) key until the "+" sign appears.
              • Motorola: Press and hold the zero key until the "+" sign appears.
              • Nokia: Press the star (*) key twice in rapid succession.
              • Pocket PC: Pull up the keyboard, hit the <123> button in the top left corner, and select "+" from the resulting screen.
              • Samsung: Press and hold the zero key until the "+" sign appears.
              • Sony Ericsson: Press and hold the zero key until the "+" sign appears.
              • Treo 270: Press the blue button and then the "G" key.
          7. How To Use Questions
            • Is there any way to remove the callback ring after I dial a number?

              The newly offered eSIM, OneSimCard Europe & More and Universal SIM cards do not use the callback to make an outgoing call in over 70 countries.

              Currently, the mobile application to remove the callback on other SIM cards is not available.

          8. 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.
          9. 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.

          10. OneSimCard General Service Questions
            • Are there any international toll-free or local Common Access Numbers (CAN)?

              OneSimCard international mobile service does not require dialing any access numbers when calling from international locations, you simply dial as you normally would when you're abroad. However, when somebody is calling to your OneSimCard phone there is an option for them to call you through a Toll Free or local number rather than dialing your European mobile number directly, which could be expensive for them. This call will instead be charged to your OneSimCard account at an additional 20c/min to the incoming rate in the country where you are receiving the call.

              When someone calls you through a Common Access Number they receive a prompt where they then enter your primary European number starting with 372 to reach you. For a direct connection, we recommend adding a Personal Extra Number (PEN) instead.

              At this time we have Toll Free and/or Local Common Access Numbers in the following countries:

              • Argentina
              • Australia
              • Austria
              • Argentina
              • Brazil
              • Canada
              • Cyprus
              • France
              • Germany
              • Greece
              • Hong Kong
              • Israel
              • Mexico
              • New Zealand
              • Russia
              • Spain
              • UK
              • USA - Toll Free as well as local Common Access Numbers in New York City, Washington DC and Los Angeles


              You can find these numbers in the User Guide or while logged in to your OneSimCard web account portal.
