79. Rates and Cost Questions
    • How much does it cost someone in the US or Canada to call to my OneSimCard cell phone?

      For Universal, Expedition, and eSIM World SIM cards, 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 Peanuts Prepaid. 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.

      For Physical 3-in-1 DataMax and DataMax eSIM, if you chose to use SIM VOIP app, your friends and family will call the PEN number you are assigned, so in most cases, there will be no tariff for them to call you, and the cost to receive the call is only $0.01/Minute.
