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.

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.
