1. OneSimCard General Service Questions
    • I have a Verizon or Sprint "World Phone"¬†from BlackBerry, Samsung, LG KP series, etc., can I use it with OneSimCard?

      Yes, if you have a World Phone from Verizon or Sprint such as the BlackBerry (Bold, Curve, Tour, Pearl, Storm, 8830); LG (Fathom); LG KP Series, HTC (Touch, Ozone, Imagio); Samsung (Saga, Intrepid, Renown) you can use it with OneSimCard service. It may only require the special dialing instructions below to make outgoing calls (there is no additional charge). Receiving calls is the same as with any other phone.

      To make an outgoing call you may need to do the following:

      Initiate your call by sending a free SMS message from the regular SMS menu (not the OneSimCard Menu) of a OneSimCard enabled phone:

      To: 9146
      Message: 00 + Country Code + Number

      For example, to call to Boston USA you should go to the SMS menu of the phone and send a message:

      To: 9146
      Message: 0015844440686
      After your SMS is sent wait approximately 3-10 seconds. You will get a callback as usual and your call will be connected to the destination number.

       

      Please Note:

      1. You can not send this SMS from the SMS OneSimCard Menu of the phone, it must be sent using your phone's standard SMS function. You will not be charged for sending this SMS to 9146.

      2. If you see on the screen that the message has not been sent, make sure that the SMS settings of your phone are correct and that the SMS Center number is set to: +3725099000

2. 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
      • 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 the OneSimCard menu or *146* by following the 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 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.


      Here is an incomplete list of compatible mobile phones with notes about specific OneSimCard compatibility. We are constantly working on updating this list. Please share with us your experience about your specific wireless phone model and we will share this information with others.
3. OneSimCard General Service Questions
    • What phone numbers are included on the global SIM card?

      Starting April 19th, 2016, our OneSimCard international SIM card comes with two phone numbers: European (Estonia) and U.S. numbers. For Canada Customers it is European and Canadian numbers. For Australian customers it is European and Australia numbers and for UK customers it is Estonia and UK Mobile numbers.

      The primary European number is based in Estonia (country code +372). Estonia is a member of the European Union and one of the most high-tech and entrepreneurial societies in the world, especially when it comes to telecommunications. The world-famous program Skype was invented by Estonian developers.

      You can choose your area code for the free 30 day U.S. and Canada PENs. Australia and UK numbers are randomly assigned. You can choose to activate your free PENs when you activate your SIM card or at a later date. Once your free PEN has been activated, it will be active for 30 days unless renewed monthly or yearly for a small cost. If you would like to choose your own U.S. or Canada, Australia or UK area code or a Toll Free number, you can also order those numbers separately.

      PLEASE NOTE: There is an additional charge of 20c/min to receive calls on your U.S. number or other PEN (except for a UK-Mobile PEN which only adds 25c per call). All SMS text messages must be sent to your primary European number, except for USA, Canada and UK Mobile SMS Enabled PENs. Receiving SMS on USA or Canada SMS Enabled PENs costs $0.09 per SMS. Receiving SMS on UK Mobile SMS enabled PEN is free. UK Mobile SMS enabled PEN will not show the outgoing SMS caller ID when used with the Europe & More SIM or the Expedition SIM. It can only show the UK number on the caller ID when used with the Universal SIM.

      Free US and Canada PENs issued before December 8th 2014 will not accept text message. They could be used only for voice calls.

      Starting June 3rd 2015, OneSimCard offers new USA and Canada PENs capable of receiving SMS. These PENs can be ordered separately and carry a charge of 9 cent per received SMS.

SMS received on such PENs can be configured so the copy of the text is always forwarded to an email of your choice. This means that you can receive these Bank, Apps and Institutions SMS not only when you travel but any time by email too. Bank Verifications PENs are ordered separately. You can learn more about these special numbers here.

9. 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.

    • Will¬†a OneSimCard international SIM card work with my mobile phone?

      If you need to unlock the phone, we suggest contacting your carrier or phone manufacturer for unlocking information or services.
