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. Troubleshooting Questions
    • I have a OneSimCard 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.
3. 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.

7. 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.

8. Rates and Cost Questions
    • How often do I need to recharge my OneSimCard account?

      Your OneSimCard global SIM card and European phone number will never expire as long as you make at least one call every two years. If you fail to make or receive at least one call every two years, your OneSimCard global SIM card and European phone number will expire and you will not be entitled to a refund even if at the time of expiration your account had a positive balance.

      However, the funds on the SIM card will expire 10 months from your last recharge and will not be refunded to you. The minimum recharge amount is $25. By simply recharging at least once every 10 months your balance will roll over. If your balance does expire, it will not be refunded to you but all you need to do to get the service working again is to log in and add funds to your SIM card. If you set up the automatic recharge, it will be canceled if you allow the funds to expire, so you will need to set automatic recharge up again once you recharge your balance.

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. 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.
