1. 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.

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. Troubleshooting Questions
    • I have a Plus SIM and my phone will not register on a roaming network, what's wrong?

      Sometimes when moving from the USA, Canada or Mexico to another country, the SIM card will need to be reset to properly register on a new country roaming network.

      • If you have the OneSimCard Menu on your phone (it may be called Sim Application Menu on iPhones or SIM Toolkit on Androids), go to the menu, scroll down to Settings and enter Service Code 2003 and confirm, then Code 000 and confirm. For older SIM cards after this enter Service Code 1101 and confirm. Turn the phone off and then back on. 

      • If you do not have access to the OneSimCard Menu then turn off your phone, remove the battery for 20 seconds, reinstall the battery and then turn back on your phone.

5. 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.

7. How To Use Questions
    • How do I check my OneSimCard balance?

      Just dial 099 "Send" from your OneSimCard phone and in few minutes the balance will be displayed on the screen of your phone. Customers with iPhones can use OneSimCard Assist app to check balances and many other things. Customers with Android phones can use OneSimCard Direct app for this.

      You can always check your current balance by logging onto your OneSimCard account at www.onesimcard.com.
8. How To Use Questions
    • Can I use a OneSimCard phone to send an SMS message?

      Of course you can! Simply send and receive SMS texts according to your phone's user manual or from the OneSimCard Menu. Receiving SMS is always free. Sending an SMS (text message) is 15-59 cents depending on the country.

      SMS messages sent to a OneSimCard phone should always be sent to the main OneSimCard mobile number rather than to an optional Extra Number, with the exception of new SMS enabled numbers in USA and Canada available since Jun 3rd, 2014. When replying from OneSimCard phone to the SMS received on USA or Canada SMS capable PEN, the main number of the SIM that starts with 372 will be displayed on the text receiver phone.


      You can also send a free SMS message to any OneSimCard customer from our web site or by sending email to 372XXXXXXXX@sms.onesimcard.com, where 372XXXXXXXX is the OneSimCard primary mobile phone number. The maximum number of daily SMS sent to the SIM over email or web is 25.

      Please bear in mind that message should be sent in English characters. In addition, it should not be longer than 160 characters including spaces.

      These 2 options of sending SMS by email provide completely free way of communicating, as it is usually free for you to send the email and costs nothing for the OneSimCard customer to receive a text message.

9. Troubleshooting Questions
    • I just activated my SIM card and can't make a successful test call. What's wrong?

      If you just activated your SIM card and can not make a test call by following the instructions in the user manual, you will likely just need to power off the phone and power it back on again. The phone should automatically re-register with one of our partner networks or you can manually select and register with a network. Remember, if you answer the test call when it rings you will be charged for the call.
      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.

10. 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 compatibily 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.

           

          Please bear in mind that Android phones can use OneSimCard Direct App available free for download from Google Play.  Using this app takes care of the Android phones compatibility issues, allows to remove the callback ring (Android OS version 5 or below) and also will automatically correct mis-dialed phone calls in most cases. iPhone users can download OneSimCard Assist App from iTunes that will do the same, 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.
