13. Troubleshooting Questions
    • The battery in my phone does not last long? It got fully drained during the flight to Europe. Why?

      There can be a number of reasons why a battery does not hold a charge. Excluding the possibility of it being a faulty battery, there is another important factor to consider. If your phone is not registered on a roaming network, the battery will drain very quickly as the phone is constantly searching for a network to register on. So, if you get on a 6 hour flight and do not turn the phone off, by the time you land at the airport your battery will be drained and you will not be able to call back home.

      The same thing will happen in those areas with spotty or weak signal network coverage - the battery will drain very fast. It is always a good idea to have an extra battery with you when you travel abroad.

14. OneSimCard General Service Questions
    • Is there a nano-SIM version available for my iPhones or other phones?

      Yes! Just select "nano size" or buy a 3-in-1 SIM that contains all 3 sim sizes during checkout.

15. 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.
          d when used with a OneSimCard.

      16. 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.
      17. Rates and Cost Questions
        • Does calling to a mobile phone cost more than calling to a land line?

          No, it does not cost more to dial an international mobile number using OneSimCard service. You will receive the same very low per minute rate whether calling to a mobile phone or to a land line.

      18. OneSimCard General Service Questions
        • Can I move Personal Extra Numbers (PENs) between SIM cards in my account?

          Yes, you can move PENs within both private and corporate accounts. There is a small fee per PEN transfer which will be deducted from the SIM card the PEN is being moved to. If there is not enough money on this SIM, the fee will be deducted from the SIM the PEN is being moved from. If neither SIM card has enough balance, you’ll have an option to recharge. Transaction records will be posted under the History menu.

      19. OneSimCard General Service Questions
        • Are Personal Extra Numbers (PENs) Mobile Numbers?

          With the exception of UK Mobile numbers, all PENs are not mobile numbers. These numbers are capable of receiving and forwarding calls and in some countries like US, CANADA and UK they are capable of receiving texts. When making outgoing calls using PENs, the Caller ID can be set to show either this PEN or the Main SIM card number. This option is available in the online account.

      20. Rates and Cost Questions
        • How much does it cost someone in the US or Canada to call to my OneSimCard cell phone?

          Many U.S. and Canadian carriers can charge more than $3/minute to connect to an Estonian mobile number, the primary mobile number for a OneSimCard global SIM card. Your SIM card includes a U.S. number which will be much less expensive for people to call.

          Callers can also use one of the Common Access Numbers (CAN) that we provide to you free of charge in more than 10 countries. Your OneSimCard account will simply be charged an additional 20c/min to the incoming rate in the country you are in to receive those calls. There is also the option of ordering a dedicated Personal Extra Number (PEN) in Canada and many other countries that will forward all calls directly to your OneSimCard cell phone. You can see the list of countries where PENs are available here:

          You can order a Personal Extra Number when placing your order or later at any time by logging in to your account. Visit our Rates & Coverage page and choose any country to view all rates.

          If you would prefer for the caller to pay for calls made, we recommend they buy Speaklonger. Using this service would guarantee a connection to your OneSimCard mobile phone from the U.S and Canada for 20c/min and it is very easy to use without switching your LD carrier.
