21. 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.

        • What is time validity of OneSimCard SIM?

          All SIM types are valid for 1 year after the last billable use - phone call, sent SMS or data use.

          The SIM balance for all types of OneSimCard SIMs is valid for 10 months after the last recharge. Each recharge extends the balance for the next 10 months period. If you do not recharge within the 10-month period, any remaining balance will be forfeited.

           

          NOTE: For Physical 3-in-1 DataMax & DataMax eSIM SIM cards, if the SIM card has no balance, the SIM will expire and be removed from the account after 7 days, unless there is a data package currently active on the SIM (not a future activation). If there is no balance on the SIM and the active data package expires, the SIM will expire 7 days following the expiration of the active data package. Additionally, if a data package is purchased, and set for future activation, the inactive data package will expire after 6 months from the date of purchase.

           

          An expired SIM can be restored for a $10.00 restoration fee plus a recharge of at least $25.00.

      25. Ordering Questions
        • What is 1SIM FUND?

          The OneSimCard Money Fund allows you to pay for OneSimCard services by means other than credit cards and also by Visa and Master Cards enrolled in the credit card security programs:

           

          Once you deposit money into your OneSimCard Money Fund through one of above methods, you can use this fund to recharge your SIM(s), order a second number, or make any other payment for orders placed at OneSimCard.com.

          OneSimCard Money Fund additions are non-refundable. However, the money you put into the fund does not expire. There are no fees applied to the fund maintenance either.

          Example 1

          You are in Kenya and can't pay using a credit card. You would like to purchase a OneSimCard SIM for $39.95, and also be able to add airtime (recharge) later. You will also need to pay for shipping.

          First step - you need to add funds to your OneSimCard Money Fund. It's up to you what amount you would like to send us, but it should be large enough to cover your purchases. Let's say you posted $200.00 to your OneSimCard Money Fund.

          Once the money is received, we will send you a confirmation email. Then you can log in to your OneSimCard.com account and place your order. It will be instantly processed and the money will be deducted from your OneSimCard Money Fund account.

          Example 2

          You have 3 SIM cards and 3 personal second numbers.

          You want to set up auto-recharge for SIM1 and SIM2 in $25 increments and the third one in $50 increments. You also want to extend (recharge) your Second Numbers every month.

          Let's say you put $500 into your OneSimCard Money Fund account. Now you can set up $25 auto-recharges on your 2 SIMs and $50 auto-recharge for your 3rd SIM, as well as and automatic extension of your second number.

          This option allows many users around the word to take advantage of OneSimCard.com services without using a credit card.

          Example 3

          You use your credit card account to add money to the 1SIMCard Money Fund. The transaction from a credit cardl is instant. Funds will be instantly added to your 1SIM Card Money Fund, and then you can use the Money Fund to make any purchase at OneSimCard.com.

           

      26. Rates and Cost Questions
        • Is there a 911 emergency number in Europe that can be used with OneSimCard service?

          Yes, in Europe the emergency number is 112. You can use 112 in Europe to report real emergencies to local authorities in the country of stay. The 3 digit number should be dialed directly without any additional digits in front of the number.

           

          For DataMax and DataMax eSIM SIM cards, while there is no voice calling feature without the use of 1SIM VoIP, which doesn’t support emergency calling, most cell phones ALWAYS allow you to call emergency numbers, even without a SIM inserted into the phone. In Europe the emergency number is 112. You can use 112 in Europe to report real emergencies to local authorities in the country of stay. The 3 digit number should be dialed directly using the regular phone app (NOT the OneSim VoIP App) without any additional digits in front of the number.

      27. Rates and Cost Questions
        • Is there a way to send a SMS to a short code number?

          The SIM card does not offer SMS service to short code numbers

          OneSimCard offers special US Phone Numbers working with the SIM or even without SIM which are capable of receiving SMS from Short Codes, like those sent by Banks, Paypal and other institutions as well as replying to short codes SMS using 1SIM VOIP app.
      28. How To Use Questions
        • Is there a mobile app that will let me recharge my account and other services?

      29. How To Use Questions
        • Can I be notified of missed calls when my phone is off or outside of a coverage area?

          Yes, for Universal, Expedition, and eSIM World Sim Cards, you will receive SMS or email notifications when you miss a call due to your phone being off or out of coverage. SMS notifications are sent when the phone is unavailable for a period up to 4 hours. Email notifications are sent, regardless of the time period, to the email address you have entered into your online voicemail profile.
