    • How do I install my eSIM?

      Before purchasing, please ensure you have verified that your device is unlocked and one of the supported devices. Installation is completed by using your phone to scan the QR code of the purchased eSIM.  You may scan the QR code by displaying it on the computer screen, another device, or a printed copy.

      If you’ve already purchased OneSimCard eSIM, you can see full installation instructions and access your QR code from the Recharge menu in your online account. Make sure eSIM is selected in the Select SIM Card drop down menu.

      If you have not purchased your eSIM yet, learn more about international eSIM here.

    • Can I use OneSimCard data (GPRS) service on my BlackBerry?

      Yes! We do offer data (GPRS) service on BlackBerry devices from models 8000 and up. This is separate from BlackBerry Internet Service (BIS) & Blackberry Enterprise Server (BES). Emails can not be pushed to the phone and BlackBerry Web Applications and Messenger will not work. However, access to web-based emails like Gmail and Yahoo as well as Internet browsing will work.


86. Troubleshooting Questions
    • I am traveling in Saudi Arabia and can receive calls, but I can't make an outgoing call. What should I do?

      Local carriers in Saudi Arabia sometimes block standard OneSimCard outgoing calls. If this happens you need to either (a) enter a compatibility code into the settings of your phone or (b) initiate your call by sending an SMS message from the regular SMS menu (not the OneSimCard menu) of your phone.

      How To Activate Compatibility Mode:

      1. Open "OneSimCard" menu
      2. Select "Settings"
      3. Agree with message by pressing "Yes"
      4. Dial digits "802" and select "OK" (screen will show message "output channel is SMS")

      Bear in mind that if you have powered your telephone down and removed and reinstalled the battery, you will need to follow the programming steps outlined above again.

      How To Deactivate Compatibility Mode:

      1. Open "OneSimCard" menu
      2. Select "Settings"
      3. Agree with message by pressing "Yes"
      4. Dial digits "801" and select "OK" (screen will show message "output channel is USSD")

      How To Dial Without Activating Compatibility Mode:

      Initiate your call by sending an SMS message from the regular SMS menu (not the OneSimCard menu) of your phone.

      To: 9146
      Message: 00 + Country Code + Number + 
      * is a star character located on the keypad

      For example, to call from Saudi Arabia to Boston USA you should go to the SMS menu of the phone and send a message:

      To: 9146
      Message: 0018574440686
      After your SMS is sent wait 3-10 seconds. You will get a callback as usual and your call will be connected to the destination number.

      Note 1: You can't send this SMS from the SMS OneSimCard menu of the phone.

      Note 2: If you see on the screen that the message has not been sent, make sure that SMS settings of your phone is complete and the SMS Center number is set to: +3725099000

       

      There are no special instructions to receive calls in these countries.

87. How To Use Questions
    • There is no OneSimCard Menu (SIM Toolkit) in my Android phone. How can I fix this?

      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.

88. 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 SIM that does not use the callback to make a call, you will just get connected.

      With OneSimCard Plus SIM or Expedition (formerly Data & Roam) SIM:

      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.

90. Ordering Questions
    • When does a Personal Extra Number (PEN) subscription start?

      New SIM card orders with PENs

      Your monthly, quarterly, bi-annual or annual subscription to a Personal Extra Number starts the moment your order has been shipped. If you do not need your Extra Number to be active right away, you can always wait and order an Extra Number later at any time by logging into your account.

      eSIM orders on onesimcard.com do not require shipping.

      PENs added to existing SIM cards

      These PENs subscriptions are activated right after the order has been processed. The activation is pretty much instant, unless your PEN order requires additional documents for verification. Please see the local number information page for the list of any additional document requirements by country.

      Free Trial PENs

      Many SIM cards come with Free Trial PENs that are inactive by default. You can activate Free trial PENs at any time from your account.

      BANK SMS Verification PEN

      The SMS Verification PEN is the only PEN that can be used without a SIM card. These PENs are activated instantly if ordered on their own or added to an existing active SIM card.
