To make a call:

• Dial 00-CountryCode-AreaCode-Number and press the TALK/SEND button.
  Example: To call OneSimCard Support in the USA you would dial 00 1 617 3138888 and press TALK/SEND. 

With Europe & More, Univesal and eSIM World that do not use the callback to make a call, you will just get connected.
 
With OneSimCard Plus SIM or Expedition (formerly Data & Roam) SIMs:

After pressing the TALK/SEND button you will see a variable message on the screen (for example 'Wait for call') which you can ignore and your phone will ring back in a few seconds. Answer this ring as you normally would answer any incoming call. Your call will then be connected.

If you are unsure about how to properly dial an international number, follow this link for detailed country by country dialing instructions.

For DataMax, and DataMax eSIM cards, you can place calls using our low cost OneSIM VoIP service. OneSim VoIP costs much less than traditional voice roaming.

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 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.

The  eSIM World, eSIM Asiania, 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.

There are two ways for SMS message to be sent:

• From the OneSimCard application menu called OneSimCard - TravelSMS. To send the message, you need to locate OneSimCard menu on the phone and then scroll down to TravelSMS menu. Sending text message this way is the least expensive and will cost you 15 cents per message from any country.
• Usual way from SMS sending menu of the phone. It cost 40 cents per text message from most countries with the exception of few countries where the rates are higher.
