72. 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.

          You want to set up auto-recharge for SIM1 and SIM2 in $25 increments and the third one in $50 increments. You also want to extend (recharge) your Second Numbers every month.

          Let's say you put $500 into your OneSimCard Money Fund account. Now you can set up $25 auto-recharges on your 2 SIMs and $50 auto-recharge for your 3rd SIM, as well as and automatic extension of your second number.

          This option allows many users around the word to take advantage of OneSimCard.com services without using a credit card.

          Example 3

          You use your credit card account to add money to the 1SIMCard Money Fund. The transaction from a credit cardl is instant. Funds will be instantly added to your 1SIM Card Money Fund, and then you can use the Money Fund to make any purchase at OneSimCard.com.

           

      76. How To Use Questions
        • How do I make a call within the country I am currently located?

          You should make any call the same way as if you were making an international call.

          For example, you are in France and need to call Paris:
          You should dial 00331XXXXXXXX. Please note that you should not dial 01 for Paris, but rather just 1 after country code 33, because Paris' code is 1.

          Dialing 0 in front of 1 is required when making a regular long distance call within France to Paris. However, when making an international call or OneSimCard call, 0 is omitted.

          For example, if you are located in Italy and need to call Rome:
          You should dial 003906XXXXXXXX, as Rome's code is 06.

        • How should I send an SMS to get charged only 15 cents per text message?

          There are two ways for SMS message to be sent:

          • From the OneSimCard application menu called OneSimCard - TravelSMS. To send the message, you need to locate OneSimCard menu on the phone and then scroll down to TravelSMS menu. Sending text message this way is the least expensive and will cost you 15 cents per message from any country.
          • Usual way from SMS sending menu of the phone. It cost 40 cents per text message from most countries with the exception of few countries where the rates are higher.
            Find detailed rate information here.
          Another way to reduce the cost of sending Text is to use the SIM VOIP app and send SMS from the app. This will reduce the cost of sending SMS significantly.


          Bear in mind that sending SMS messages to the abbreviated special SMS destinations like voting, music downloads, etc. will cost you $9.00 per message.
