41. OneSim VoIP
    • What is required to use the OneSim VoIP mobile application?

      OneSimCard VoIP requires you to order a compatible Personal Extra Number (PEN). Most of the PENs we offer are OneSim VoIP enabled. You also need to have an Android phone with software version 4.2 or higher, or Apple device (iPhone, iPaed, iPod Touch) with iOS 6.1 or higher.

      Once you have an active OneSim VoIP enabled PEN, you will be able to see the option to create a OneSim VoIP account in the My SIM Cards menu of your online account.

42. 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.


      If your phone is built on Android, you can download an application that will remove the callback ring completely (Android OS version 5 or below) called OneSimCard Direct from Google Play.
43. Rates and Cost Questions
    • What is the cost to make calls from a OneSimCard phone to another OneSimCard phone?

      It depends on the country you're in when making the call. In many countries there is a special low rate of just $0.25/min to call another OneSimCard phone (only when dialing the other OneSimCard user's primary mobile number, not a Personal Extra Number). In other countries your cost will be our standard low outgoing call rate from that country.

      Example 1: two OneSimCard users are in Italy and one calls the other, the cost will be $0.25/min for the caller and free for the receiver.


      Visit our Rates & Coverage page and choose any country to view its current rates. Use the dropdown menus to see rates for calling to/from other countries.

      PLEASE NOTE: If you activate a discount call plan, the special rate to make OneSimCard-to-OneSimCard calls will not be available. You will be charged for those calls according to the discount call plan rate.

44. 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.

        • Which phone number will be shown on the caller ID when I make a call using OneSim VoIP?

          Your active OneSim VoIP Personal Extra Number (PEN) will be shown on the caller ID.
      46. Troubleshooting Questions
        • Can I move balances from one SIM card to another?

          We allow moving balances from one SIM card to another in the following cases:
          • Corporate Accounts - anytime.
          • Individual Accounts - only when a SIM card is lost or stolen. The remaining balance from your lost or stolen SIM card can be transferred to another SIM card on your account or you can order a new SIM card if you would like to keep your original European number from the lost SIM.
      47. Troubleshooting Questions
        • I have an unlocked iPhone 4, 5 or 6 and am receiving charges for SMS sent to a UK mobile number 447786205094. Why?

          This is a known issue with Apple's Facetime and iMessage applications on iPhone 4, 5 and 6 phones. We recommend disabling Facetime and iMessage so it will not be able to automatically send SMS to this 447786205094 number. Any SMS sent to this number automatically by your phone can not be refunded by OneSimCard. Additional questions regarding iPhone 4 applications and how they communicate should be directed to Apple Support.
      48. OneSim VoIP
        • I can make calls through OneSim VoIP. However incoming calls are going through my roaming SIM. What's wrong?

          If your incoming calls are not being routed through the OneSim VoIP app then you are either not connected to Wi-Fi or the OneSim VoIP app is not active.

          Please make sure to check your phone's sleep settings, as they are usually preset to have Wi-Fi turn off when the phone enters sleep mode. To prevent this and to keep OneSim VoIP active for incoming calls, find the settings in your phone and set it so Wi-Fi does not turn off when the phone enters sleep mode.

          Note: if the OneSim VoIP logo on the top of your phone display is gray then you will not be able to receive calls through the application. When the logo is yellow that means you are connected and can receive calls through OneSim VoIP.

        • What are the advantages of using OneSim VoIP?

          The main advantages are significant cost savings and the ability to call from countries where there is no roaming coverage available.
          OneSim VoiP can be used from any Android or Apple ( iOS) device to make international LD calls even when you are not traveling. OneSim VoIP does not require having OneSimCard SIM being installed in the phone. OneSim VoIP can be used with Wi-Fi or 3G - no difference. You just need to have OneSimCard account with the SIM VoIP capable PEN. Calling using OneSim VoIP will cost most of the time less than any other way of calling.
          OneSim VoIP is available with all 3 types of SIM card we offer - Plus, Data & Roam and Europe & More.
      50. Troubleshooting Questions
        • Does iPhone Hotspot work with OneSimCard?

          Yes. All unlocked iPhones' Hotspot feature works with OneSimCard SIM.

           
          There are a few settings to make sure for this to function properly on your iPhone:
          1. Settings - Cellular - Cellular Data - ON
          2. Settings - Cellular - Data Roaming - ON
          3. Settings - Cellular - Cellular Data Network - Cellular Data - APN=send.ee for Plus SIM and APN=apn                                                                                                             for Data & Roam SIM
          4. Settings - Wi-Fi - ON
          5. Settings - Personal Hotspot - ON. 
          After turning the Hotspot on, you should stay on the Personal Hotspot screen of your iPhone for SSID of your phone to show up on other Wi-Fi devices, so you can get connected. After you connected to the Hotspot, you can leave the screen. Alternatively, you can always use Bluetooth or USB connection to provide the internet access from your OneSimCard iPhone Hotspot to your other devices.
          Customers with jail-broken iPhones can use My-Wi app from Cydia, which provides more options and is easier to use.
