42. How To Use Questions
    • Is there any way to remove the callback ring after I dial a number?

      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.

43. OneSim VoIP
    • What is required to use the OneSim VoIP mobile application?

      OneSimCard VoIP requires you to order a compatible Personal Extra Number (PEN). Most of the PENs we offer are OneSim VoIP enabled. You also need to have an Android phone with software version 8 or higher, or Apple device (iPhone, iPad, iPod Touch) with iOS 6.1 or higher.

      Once you have an active OneSim VoIP enabled PEN, you will be able to see the option to create a OneSim VoIP account in the My SIM Cards menu of your online account. NB: YOU MUST create the 1SIM VoIP account in your account online on the "My SIM Cards" menu. Simply purchasing a PEN and  downloading the mobile app DOES NOT create the VoIP account.

44. Ordering Questions
    • Can I use OneSimCard service if my phone is locked?

      Yes. There are a few options available if your phone is locked to the carrier that sold you the phone.

      • Try contacting the carrier to see if they unlock it for you.
      • You can purchase a travel phone bundle with the SIM at

                 http://www.onesimcard.com/international-cell-phones/

      You can purchase a MI-FI device with aOneSimCard SIM card (Universal, Expedition or DataMax physical SIM card) at http://www.onesimcard.com/international-cell-phones/. The Mi-Fi device will provide your locked Android or iPhone with mobile data over Wi-Fi connection that you can use on your phone for Voice and Texts using SIM VOIP app, as well as data for web browsing, email, GPS navigation, etc.
45. How To Use Questions
    • How can I dial '+' on my phone when making call?

      Note: You can always dial 00 instead of + when making outgoing calls. For example, to reach OneSimCard customer service in the USA you can just dial 001 617 3138888.

      You should consult the phone manual for this info. Different manufacturers have specific ways to access the '+' key, so make sure you know yours.

      Here are few known ways:

      • Bosch: Press and hold the star (*) key until the "+" sign appears.
      • Motorola: Press and hold the zero key until the "+" sign appears.
      • Nokia: Press the star (*) key twice in rapid succession.
      • Pocket PC: Pull up the keyboard, hit the <123> button in the top left corner, and select "+" from the resulting screen.
      • Samsung: Press and hold the zero key until the "+" sign appears.
      • Sony Ericsson: Press and hold the zero key until the "+" sign appears.
      • Treo 270: Press the blue button and then the "G" key.

       

46. Ordering Questions
    • Do I need to activate the SIM card when my order is received or purchased from a retail store?

      Yes, you will need to activate the SIM card once the order is received.

      All OneSimCard international SIM cards and international cell phones with SIM cards are shipped inactive to prevent theft and improve security. Only the person who placed the order for OneSimCard service can activate it.

      Activation is very simple: When you receive the SIM, just log in to your account at www.OneSimCard.com and click the large Activate button you will see in the middle of the screen.

      Retail Customers: If you purchased your SIM card through an online or brick-and-mortar retail store, you should have received activation instructions inside the product packaging. To activate retail SIM cards, go to www.OneSimCard.com/Retail enter your new OneSimCard international mobile number and fill out the form to register and activate the SIM card. You will be provided specific instructions on the registration page.

47. Rates and Cost Questions
    • Are there any monthly fees or connection charges?

      There are no monthly fees or connection charges for using OneSimCard international cell phone service.

      If you order an optional Personal Extra Number (PEN), there is a small periodic fee to keep the PEN active based on how you choose to be billed (from $1.67 per month). There is also an additional charge to receive a call through any Extra Number. View our Rates & Coverage page and click on any country to view our available Extra Numbers and associated costs.

48. Rates and Cost Questions
    • How often do I need to recharge my OneSimCard account?

      For Universal E, Expedition E, eSIM World E, eSIM Asiania, Plus, Europe & More, & Standard SIM Cards, the international SIM card phone number and account will expire if no outgoing usage is made for 12 months. The outgoing usage could be any of the following: Call made from the phone, SMS sent from the phone or any Data Usage.

      Personal Extra Numbers will stay active as long as they have been funded properly.

      The SIM card balance is valid for 10 months. The balance will continuously roll over to the next 10 month period provided that at least $25 is added within 10 months after the last recharge.

      If the balance expires, the service can still be used after a new recharge of the SIM card.

      For Physical 3-in-1 DataMax & DataMax eSIM SIM Cards, the SIM card and account will expire if no outgoing usage is made for 12 months. The outgoing usage could be any of the following: Call made from the OneSIM VoIP App, SMS sent from the OneSim VoIP app or any Data Usage.

      Personal Extra Numbers will stay active as long as they have been funded properly and the SIM hasn’t expired. If the SIM card expires, but then is restored ($10 Restoration Fee applies), the PEN will be re-attached to the SIM card, as long as the PEN hasn’t expired based on the time period for which the PEN was purchased.

      The SIM card balance is valid for 10 months. The balance will continuously roll over to the next 10-month period provided that at least $25 is added within 10 months after the last recharge.

      If the SIM card balance expires, the SIM will expire and be removed from the account after 7 days, unless there is a data package currently active on the SIM (not a future activation). If there is no balance on the SIM and the active data package expires, the SIM will expire 7 days following the expiration of the active data package. So, to keep the SIM active you need to either keep a balance on the SIM or an active data package. 

      NOTE: If there is balance on the SIM card, but no data is used for 15 consecutive days, the SIM card will be blocked/suspended. To unblock the SIM card, simply go to your account portal and in the "My SIM cards" tab, click on "Unblock" on the "SIM Type" line.

      An expired SIM can be restored for a $10.00 restoration fee plus a recharge of at least $25.00.

       

49. eSIM
    • Can I use Facetime, WhatsApp, Telegram, Discord, iMessage, and other messaging Apps with eSIM?

      Yes, you can use your messaging apps with eSIM World, which now offers a mobile number ID. 

      For DataMax eSIM, you can use these Apps as you already do. Please ensure your messaging account is already setup with your primary carrier’s phone number because you cannot sign up for these services with the DataMax eSIM number.

      Additionally, the eSIM data service can be used for the actual data part of your communications. So, when you are installing eSIM on phone, you can select the Primary service for Facetime and iMessage and then if your selected eSIM to be your primary data service, the communications will go over eSIM mobile data.
