101. 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.

102. OneSim VoIP
    • Do I need to have a OneSimCard SIM card installed in my phone to use OneSim VoIP?

      No. OneSimCard SIM is not required to be installed in the phone for OneSim VoIP to be used. However, you do need to have OneSimCard account with a VoIP capable PEN.
103. 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.

      • 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.
104. How To Use Questions
    • How do I prevent the service from expiring?

      The OneSimCard phone number has no expiration, provided you made at least 1 call or sent an SMS once every 18 months.

      However, the funds on the SIM expire 10 months after your last recharge. The minimum recharge amount is $25. You can keep the balance from expiring by simply recharging at least once every 10 months. If you let your balance expire, then all you need to do to get the service up and running again is to log in and add funds to your SIM card. Automatic recharge will be canceled if you let your funds expire.

105. eSIM
    • Can eSIM be used for Data, Calls and Texts?

      Yes, as of March 3rd, 2020, OneSimCard eSIM can be used for Mobile Data, Voice and Texts. However, you can still use the OneSim VOIP app option with a Personal Extra Number (PEN) for additional savings on calling and texting
106. OneSimCard General Service Questions
    • Will I get a bill for using OneSimCard service?

      No. OneSimCard service is a prepaid service. You will not be able to spend more than you put on the SIM, except when you set the automatic recharge of the SIM. There are three simple ways to add funds to the balance of the SIM: from on-line, from the mobile phone and by setting up an automatic recharge. This pertains to both - purchased SIM cards and rentals.

108. 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.

           

           

      109. Rates and Cost Questions
        • How does OneSimCard compare to the international roaming from the largest US carriers?

          OneSimCard can help you save a lot of money on international roaming abroad over large domestic carriers. Check out these rate tables to compare international roaming offerings from AT&T, Verizon, Sprint and T-Mobile.

      110. OneSim VoIP
        • Can I used OneSim VoIP over the Internet Data offered by OneSimCard SIM? Will it save me anything?

          In countries where the cost of using mobile Internet Data is below 20 c/MB, the cost of using SIM VoIP over the data is comparable or smaller than the actual calling rate from the country.
          As a rule ot thumb, the SIM VoIP will use 1MB /Min of talk time. So if the cost of Data in the country is 10 c/MB, then 1 minute SIM VoIP call will cost you 12 cent /minute. You need to have a 3G connection in order for SIM VoIP to work this way.
