1. OneSimCard General Service Questions
    • What phone numbers are included on the global SIM card?

      Starting April 19th, 2016, our OneSimCard international SIM card comes with two phone numbers: European (Estonia) and U.S. numbers. For Canada Customers it is European and Canadian numbers. For Australian customers it is European and Australia numbers and for UK customers it is Estonia and UK Mobile numbers.

      The primary European number is based in Estonia (country code +372). Estonia is a member of the European Union and one of the most high-tech and entrepreneurial societies in the world, especially when it comes to telecommunications. The world-famous program Skype was invented by Estonian developers.

      You can choose your area code for the free 30 day U.S. and Canada PENs. Australia and UK numbers are randomly assigned. You can choose to activate your free PENs when you activate your SIM card or at a later date. Once your free PEN has been activated, it will be active for 30 days unless renewed monthly or yearly for a small cost. If you would like to choose your own U.S. or Canada, Australia or UK area code or a Toll Free number, you can also order those numbers separately.

      You can order an unlimited number of Personal Extra Numbers (PEN) in many countries including:

      Have phone numbers in as many as 61 different countries on one SIM card! You can also set your Caller ID to display a Personal Extra Number instead of your primary European number.

      You can view a complete list of available numbers  here 

      PLEASE NOTE: There is an additional charge of 20c/min to receive calls on your U.S. number or other PEN (except for a UK-Mobile PEN which only adds 25c per call). All SMS text messages must be sent to your primary European number, except for USA, Canada and UK Mobile SMS Enabled PENs. Receiving SMS on USA or Canada SMS Enabled PENs costs $0.09 per SMS. Receiving SMS on UK Mobile SMS enabled PEN is free. UK Mobile SMS enabled PEN will not show the outgoing SMS caller ID when used with the Europe & More SIM or the Expedition SIM. It can only show the UK number on the caller ID when used with the Universal SIM.

      Free US and Canada PENs issued before December 8th 2014 will not accept text message. They could be used only for voice calls.

      Starting June 3rd 2015, OneSimCard offers new USA and Canada PENs capable of receiving SMS. These PENs can be ordered separately and carry a charge of 9 cent per received SMS.

      Starting January 1st 2018, OneSimCard offers special new USA - SMS for Bank verifications PENs. These USA and Canada PENs are capable of receiving SMS from most US and Canada financial institutions -most banks, Paypal, credit cards etc, as well as some apps like Uber ( but not from Whatsap).  These numbers are also SIM VOIP capable and will work as a regular US PEN for incoming calls and SMS. SMS received on such PENs can be configured so the copy of the text is always forwarded to an email of your choice. This means that you can receive these Bank, Apps and Institutions SMS not only when you travel but any time by email too. Bank Verifications PENs are ordered separately. You can learn more about these special numbers here.

4. OneSimCard General Service Questions
    • Can I keep receiving calls made to my regular cell phone or landline numbers while traveling abroad?

      Yes, you can easily forward calls from your regular cell phone number, home phone, office, etc. to your OneSimCard phone while you're abroad!

      Your OneSimCard international SIM card comes with both a European and U.S. number. To forward your regular U.S. numbers to the SIM, just set them to forward to the U.S. number that's included with your SIM card.

      You can also order unlimited Personal Extra Numbers (PEN) - Local or Toll Free - in many different countries, including USA, Canada, UK, France, Italy and Spain. For example, if you work or live in the UK and want to keep receiving calls made to your regular UK numbers, just add a UK PEN to your SIM card and set up call forwarding to that new number.

      Calls received through a PEN will be charged an additional 20c/min to the incoming rate of the country you are in. The exception is calls received through a UK-Mobile PEN which is only charged an additional 25c per call.

      Please Note: Your subscription to a Personal Extra Number starts the moment your order is shipped. If you do not need your PEN to be active right away, you can always wait and order a PEN later at any time by logging in to your account.

      Different carriers use different ways of programming call forwarding. Below are instructions to setup call forwarding with various US wireless carriers. We urge you to test the call forwarding a few days prior to your trip, and to call your US wireless carrier for assistance if needed.

5. OneSimCard General Service Questions
    • Are there any international toll-free or local Common Access Numbers (CAN)?

      OneSimCard international mobile service does not require dialing any access numbers when calling from international locations, you simply dial as you normally would when you're abroad. However, when somebody is calling to your OneSimCard phone there is an option for them to call you through a Toll Free or local number rather than dialing your European mobile number directly, which could be expensive for them. This call will instead be charged to your OneSimCard account at an additional 20c/min to the incoming rate in the country where you are receiving the call.

      When someone calls you through a Common Access Number they receive a prompt where they then enter your primary European number starting with 372 to reach you. For a direct connection, we recommend adding a Personal Extra Number (PEN) instead.

      At this time we have Toll Free and/or Local Common Access Numbers in the following countries:

      • Argentina
      • Australia
      • Austria
      • Argentina
      • Brazil
      • Canada
      • Cyprus
      • France
      • Germany
      • Greece
      • Hong Kong
      • Israel
      • Mexico
      • New Zealand
      • Russia
      • Spain
      • UK
      • USA - Toll Free as well as local Common Access Numbers in New York City, Washington DC and Los Angeles


      You can find these numbers in the User Guide or while logged in to your OneSimCard web account portal.

6. OneSimCard General Service Questions
    • Can I move Personal Extra Numbers (PENs) between SIM cards in my account?

      Yes, you can move PENs within both private and corporate accounts. There is a small fee per PEN transfer which will be deducted from the SIM card the PEN is being moved to. If there is not enough money on this SIM, the fee will be deducted from the SIM the PEN is being moved from. If neither SIM card has enough balance, you’ll have an option to recharge. Transaction records will be posted under the History menu.

7. OneSimCard General Service Questions
    • Can I forward calls from my OneSimCard phone to another number?

      Yes. Your OneSimCard mobile number can be forwarded to almost any other number around the world! It's 100% free to forward your OneSimCard phone number to many countries, including to U.S. or Canadian numbers. Forwarding to some countries, as well as to satellite phones, will carry a forwarding charge as listed in the Rates & Coverage page on OneSimCard.com. There are a few exceptions where calls can not be forwarded to certain numbers.

      To enable/disable call forwarding from your online account:

      Log in at OneSimCard.com and go to the My SIM Cards menu. Select your SIM card number and enable/disable Call Forwarding on this screen.

      To enable/disable call forwarding from your phone:

      Dial *146*081*XXXXXXXXXXXXX# and press Send/Talk (where XXXXXXXXXXXXX is the forward-to number in international format: 00+countrycode+number)

      Newer SIM cards use *81* instead of *081*

      Example: to forward to U.S. number 1-617-555-1212, dial *146*081*0016175551212# and press Send/Talk.

      If you get an "Unknown Format?" message, dial *146*81*0016175551212#

      To disable call forwarding, dial *146*080# and press Send/Talk. If you get an "Unknown Format?" message dial *146*80# and press Send/Talk.

8. OneSimCard Rentals
    • How can I set up the Personal Extra Number (PEN) on my rental order?

      Once your order is processed and shipped, you will receive a notification email. At this point, you can log in to your account and:
      1. Activate your SIM card(s) (you should wait to activate until after you receive the package)
      2. Once the SIM is activated, you can set up the PEN. You will see the link on the screen in the Recharge Menu. The PEN activation is done instantly. 

      If you activate the Free US PEN and your travel is under 30 days, it will stay active for the duration of your travel. If you will be traveling for more than 30 days and require the use of the PEN beyond 30 days, you must renew your PEN for a fee before it expires.

      Alternatively, you can order a PEN in your local area or in another country if you require one. 

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

      The newly offered eSIM, OneSimCard Europe & More and Universal SIM cards do not use the callback to make an outgoing call in over 70 countries.

      Currently, the mobile application to remove the callback on other SIM cards is not available.

10. Ordering Questions
    • When does a Personal Extra Number (PEN) subscription start?

      Your monthly, quarterly, bi-annual or annual subscription to a Personal Extra Number starts the moment your order is shipped. If you do not need your Extra Number to be active right away, you can always wait and order an Extra Number later at any time by logging in to your account.
