1. How To Use Questions

    • Can I check my Voice Mail from a phone other than my OneSimCard phone?

      Yes. You can access the Voice Mail from other phones.

      First you need to set up a voicemail password by either calling from your OneSimCard phone or logging in to your account and clicking on the Voicemail link.

      Once the password is set up, you can dial voice mail access number:
      Toll Free access number for customers in the U.S. or Canada to retrieve voicemail for free: 1-866-703-4770

      Local U.S. number for worldwide customers to retrieve voicemail: 1-213-805-2905

      New Online Voicemail Feature: You can now listen to voicemail for free by logging in to your account and clicking on the Voicemail link. There, you can also set voicemail to be emailed to you as an audio file and change passwords and other settings.

      IMPORTANT NOTE: Voicemail messages will be automatically purged from your inbox after one month, so please be sure to save the content of any important messages before they are deleted.
2. OneSim VoIP

    • Does voicemail work with OneSim VoIP?

      Yes. If you are not available to answer the OneSim VoIP call or if the OneSim VoIP app is turned off, the call will be routed through our standard roaming network. If the call is not answered it will be sent to your OneSimCard voicemail box.
3. Rates and Cost Questions

    • Are there any discount call (voice) plans available for Europe or other countries?

      Yes, discount calling plans are available on select sim cards.

      "Discount A" Voice Calls Plan

      You can subscribe to the Discount Call Plan A for Europe (see country list below) and Turkey for just $3.99! Subscription is good for 30 days and will not automatically renew. This plan is available on the Plus and Universal SIM cards.

      Once the discount plan is activated, you will be able to make calls from the countries below for only $0.15/min starting with the second minute! The first minute will be charged at the regular outgoing call rate:

      PLEASE NOTE: If you activate the discount A call plan, the special rate to make OneSimCard-to-OneSimCard calls and to call the voicemail system will not be available. Activation of this discount plan will also cancel the Discount B - Bucket of Minutes to USA, Canada, Australia and New Zealand. You will be charged for those calls according to the discount call plan rate. Discount rate not applicable for calls to Customer Support. Calling to some countries costs extra. Please consult our rates page for more details.

      The discount voice subscription can be activated online by logging in to your account or by sending a command from your phone.

4. Rates and Cost Questions

    • Can I send an SMS to or from a Common Access Number or Personal Extra Number?

      You can't send SMS to a Common Access Number (CAN). Common Access Numbers and majority of Personal Extra Numbers are for Voice Calls only.
      Starting December 8th, 2014 all new USA and Canada Personal Extra Numbers are capable of receiving mobile SMS. SMS received on US or Canada PEN will incur 9 cent charge.

      Note: US and Canada PEN can receive only actual mobile SMS from mobile phones. Alert and verification SMS sent from web sites like Google, Yahoo or your bank will not be delivered to US or Canada PENs due to the way these web sites send there messages.

5. 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.

           

           
      6. Ordering Questions

        • Can I use OneSimCard service if my phone is locked?

          Yes. There are few options available if your phone is locked to the carrier that sold you the phone.

          • Try contacting the carrier to see if they unlock it for you.

           

          • You can purchase a travel phone bundle with the SIM at

                     http://www.onesimcard.com/international-cell-phones/

          • You can purchase a MI-FI device with OneSimCard  SIM at http://www.onesimcard.com/international-cell-phones/. The Mi-Fi device will provide your locked Android or iPhone with mobile data over Wi-Fi connection that you can use on your phone for Voice and Texts using SIM VOIP app, as well as data for web browsing, email, GPS navigation, etc.
      7. 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.
      8. 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)
