11. 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.
          d when used with a OneSimCard.


      12. How To Use Questions
        • Is there any way to remove the callback ring after I dial a number?

          The newly offered OneSimCard Europe & More does not use the callback to make an outgoing call.

           

          With OneSimCard Plus or Data & Roam SIM:

          Normally, when you make a call with OneSimCard the phone will ring back within a few seconds after dialing and you will then get connected. You can eliminate this callback if you have a smarphone running Android (OS version 5 or below) by downloading and installing our OneSimCard Direct mobile app. Alternatively, you can purchase our Global Dual SIM Quad-Band GSM Unlocked International Cell Phone which has built-in software that automatically removes the callback.

          For phones using Android (OS version 5 or below):

          OneSimCard Direct allows you to hide the callback and makes it easier to make a call directly from your phone's address book.

          Once the application is installed on your phone, please run it once and then turn your phone off and back on. You will then be able to dial without receiving the callback.
      13. Rates and Cost Questions
        • I was charged a large amount for mobile data service even though I barely used data, what happened?

          Each mobile data session is charged for a minimum of 10kB usage. Even if you check just one 3k email you will be charged for 10kB of usage. In some countries this can be over 30c per session, however in Europe and elsewhere it can be as little as 1c. Check all rates.

          Please note: Some phones, like iPhones and other smartphones, can access data without you even knowing it if you have data enabled. We strongly recommend checking the settings on your phone or disabling GPRS from your OneSimCard account if you will not be needing data service. By default, all SIM cards are pre-programmed with GPRS data service disabled.

      14. Rates and Cost Questions
        • Is there a monthly or 30-day credit card spending limit for OneSimCard service?

          To reduce fraud, there is 30-day credit card spending limit set for each individual account. You will only be able to charge up to a certain amount during any 30-day period. You can see your current limit by logging in to your OneSimCard account and going to the Purchase History menu. There, you will find a Credit Card Authorization form available for download. If you would like to increase your monthly credit card spending limit, please download the Authorization form and submit it back to OneSimCard as instructed on the form.

          We strongly suggest that you set your monthly credit card limit before going overseas as dealing with the form on the road can be much more difficult.
      15. 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

          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.
      16. OneSim VoIP
        • How do I know if the Personal Extra Number (PEN) I currently have is OneSim VoIP compatible?

          Log in to your OneSimCard account, go to the My Sim Cards menu and scroll down. If your PEN is VoIP compatible you will see an option to create a OneSim VoIP account. At this time all OneSimCard PENs are SIM VOIP capable except for UK Mobile numbers.
      17. M2M SIM Cards
        • Will I be able to see the usage details for my M2M SIM card?

          Yes, all usage details and charges are available in the My SIM Card menu of the customer account.

          In addition, you can filter SIM cards using the following parameters:

          • SIM cards with Data Package to be activated when the traffic starts moving
            • This option allows you to view those SIM cards where data packages have been set up for activation and will be triggered automatically once data is moving on the SIM.

          • SIM cards with data packages scheduled to get activated later
            • This option displays SIM cards with data packages scheduled to be activated on a particular date.

          • SIM with the balance below X
            • This option displays SIM cards with low balances that might need your attention to ensure service is not interrupted due to lack of funds.

          • SIM cards with the data usage over the last X DAYS above Y MB
            • This option displays SIM cards with the data usage exceeding your projected usage or could be used for other usage monitoring applications.

          • SIM Cards with the $ spending – Top X % in 30 days
            • This option displays SIM cards that are consuming the most funds for data and SMS usage.

          • SIM cards that reached monthly additions limit
            • If monthly spending limits for SIM cards are set, this option allows you to view SIM cards that already reached the monthly limit and are temporarily not in service until additional funds are added.

          • SIM cards 10% below monthly additions limit
            • This option allows you to view the range of SIM cards that are about to reach the monthly limit (If you have set limits on the SIM cards.)
      18. Troubleshooting Questions
        • I have an Apple iPhone. When I dial following your instructions it does not work. What's wrong?

          This reply does not apply to OneSimCard Europe & More SIM or newer SIM cards purchased after January 2017.
          Older SIM cards might require entering the compatibility code on your  iPhone.

          How to activate compatibility mode:

           1. Locate OneSimCard Menu.

           On iPhones it is called SIM Applications menu and is located under Settings- Phone menu

          1. Open "OneSimCard" menu ( SIM Applications)
          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.


          We strongly recommend you to watch very short video tutorials for iPhone that will help you to understand how to make calls, SMS and data on your OneSimCard iPhone.
          If your phone is not Jail-Broken, you still can use OneSimCard Assist app available from iTunes. This app will help you to dial numbers properly by correcting mis-dialed numbers and will allow easy access to OneSimCard functions like checking balance, recharging your SIM, activating discounts and others.

          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 is for older SIM Cards. Newer SIM cards do not require entering any codes in iPhone or other types of phones.
