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.

The Free 30 days U.S., Canada, Australia and UK numbers are randomly assigned and you can choose to assign the number when you activate your SIM card or at a later date. Once your free PEN is assigned, it will be active for 30 days unless renewed monthly or yearly for a small cost. If instead you would like to choose your own U.S. or Canada, Australia or UK area code or a Toll Free number, you can order this 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 Verifcations PENs are ordered separately. You can learn more about these special numbers here.

Many U.S. and Canadian carriers can charge more than $3/minute to connect to an Estonian mobile number, the primary mobile number for a OneSimCard global SIM card. Your SIM card includes a U.S. number which will be much less expensive for people to call.

Callers can also use one of the Common Access Numbers (CAN) that we provide to you free of charge in more than 10 countries. Your OneSimCard account will simply be charged an additional 20c/min to the incoming rate in the country you are in to receive those calls. There is also the option of ordering a dedicated Personal Extra Number (PEN) in Canada and many other countries that will forward all calls directly to your OneSimCard cell phone. You can see the list of countries where PENs are available here:

You can order a Personal Extra Number when placing your order or later at any time by logging in to your account. Visit our Rates & Coverage page and choose any country to view all rates.

If you would prefer for the caller to pay for calls made, we recommend they buy Speaklonger. Using this service would guarantee a connection to your OneSimCard mobile phone from the U.S and Canada for 20c/min and it is very easy to use without switching your LD carrier.

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.
