51. Ordering Questions
    • What is 1SIM FUND?

      The OneSimCard Money Fund allows you to pay for OneSimCard services by means other than credit cards and also by Visa and Master Cards enrolled in the credit card security programs:

       

      Once you deposit money into your OneSimCard Money Fund through one of above methods, you can use this fund to recharge your SIM(s), order a second number, or make any other payment for orders placed at OneSimCard.com.

      OneSimCard Money Fund additions are non-refundable. However, the money you put into the fund does not expire. There are no fees applied to the fund maintenance either.

      Example 1

      You are in Kenya and can't pay using a credit card. You would like to purchase a OneSimCard SIM for $39.95, and also be able to add airtime (recharge) later. You will also need to pay for shipping.

      First step - you need to add funds to your OneSimCard Money Fund. It's up to you what amount you would like to send us, but it should be large enough to cover your purchases. Let's say you posted $200.00 to your OneSimCard Money Fund.

      Once the money is received, we will send you a confirmation email. Then you can log in to your OneSimCard.com account and place your order. It will be instantly processed and the money will be deducted from your OneSimCard Money Fund account.

      Example 2

      You have 3 SIM cards and 3 personal second numbers.

      You want to set up auto-recharge for SIM1 and SIM2 in $25 increments and the third one in $50 increments. You also want to extend (recharge) your Second Numbers every month.

      Let's say you put $500 into your OneSimCard Money Fund account. Now you can set up $25 auto-recharges on your 2 SIMs and $50 auto-recharge for your 3rd SIM, as well as and automatic extension of your second number.

      This option allows many users around the word to take advantage of OneSimCard.com services without using a credit card.

      Example 3

      You use your credit card account to add money to the 1SIMCard Money Fund. The transaction from a credit cardl is instant. Funds will be instantly added to your 1SIM Card Money Fund, and then you can use the Money Fund to make any purchase at OneSimCard.com.

       

52. How To Use Questions
    • How do I make a call using OneSimCard global cell phone service?

      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 Physical 3-in-1 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.

53. How To Use Questions
    • Can I use a OneSimCard phone to send an SMS message?

      Of course you can! Simply send and receive SMS texts according to your phone's user manual or from the OneSimCard Menu. Receiving SMS is always free. Sending an SMS (text message) is $0.15 - $1.50 depending on the country.

      SMS messages sent to a OneSimCard phone should always be sent to the main OneSimCard mobile number rather than to an optional Extra Number, with the exception of new SMS enabled numbers in USA, Canada and UK Mobile available since Jun 3rd, 2014. When replying from OneSimCard phone to the SMS received on USA or Canada SMS capable PEN using Europe & More sim or the Expedition SIM, the main number of the SIM that starts with 372 will be displayed on the text receiver phone. With the Universal SIM, you can select what caller ID will be shown on the SMS receiving party phone.

      You can also send SMS messages from OneSim VOIP app at much lower rates. Note: for Physical 3-in-1 Datamax and Damax eSIM all SMS messages MUST be sent through the OneSim VoIP App with PEN.


      You can also send a free SMS message to any OneSimCard customer from our web site or by sending email to [email protected], where 372XXXXXXXX is the OneSimCard primary mobile phone number. The maximum number of daily SMS sent to the SIM over email or web is 25.

      Please bear in mind that message should be sent in English characters. In addition, it should not be longer than 160 characters including spaces.


      These 2 options of sending SMS by email provide completely free way of communicating, as it is usually free for you to send the email and costs nothing for the OneSimCard customer to receive a text message.

54. How To Use Questions
    • How do I make a call within the country I am currently located?

      You should make any call the same way as if you were making an international call.

      For example, you are in France and need to call Paris:
      You should dial 00331XXXXXXXX. Please note that you should not dial 01 for Paris, but rather just 1 after country code 33, because Paris' code is 1.

      Dialing 0 in front of 1 is required when making a regular long distance call within France to Paris. However, when making an international call or OneSimCard call, 0 is omitted.

      For example, if you are located in Italy and need to call Rome:
      You should dial 003906XXXXXXXX, as Rome's code is 06.

56. 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.
