54. 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.

56. Rates and Cost Questions
    • What is time validity of OneSimCard SIM?

      All SIM types are valid for 1 year after the last billable use - phone call, sent SMS or data use.

      The SIM balance for all types of OneSimCard SIMs is valid for 10 months after the last recharge. Each recharge extends the balance for the next 10 months period. If you do not recharge within the 10-month period, any remaining balance will be forfeited.

       

      NOTE: For Physical 3-in-1 DataMax & DataMax eSIM SIM cards, if the SIM card has no balance, 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. Additionally, if a data package is purchased, and set for future activation, the inactive data package will expire after 6 months from the date of purchase.

       

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

       

57. eSIM
    • What is an eSIM & how does it work?

      eSIM is not a physical SIM. It is a piece of software downloaded to a compatible phone. So there is no shipping involved with delivering eSIM.


      eSIM makes your iPhone or Android phone to be a dual SIM phone. This means that you can use two sim cards on the phone at the same time. You can select which SIM card is used for calls and texts, and which one is used for data. You can select which sim card is to be the primary and which one not to be used. You can make these changes from the settings of your phone at any time. In short - eSIM offers greater flexibility to your eSIM compatible phone. It allows you to use the service provider of your choice - whether you are traveling or staying home.


      OneSimCard eSIM can be installed only on a single device. It can't be moved to another device, but it can be re-installed on the original device up to 3 times if required.
58. Troubleshooting Questions
    • I have an Apple iPhone. When I dial following your instructions it does not work. What's wrong?

      This reply does not apply to OneSimCard Europe & More SIM or newer SIM cards purchased after January 2017.
      Older SIM cards might require entering the compatibility code on your  iPhone.

      How to activate compatibility mode:

       1. Locate OneSimCard Menu.

       On iPhones it is called SIM Applications menu and is located under Settings- Phone menu

      1. Open "OneSimCard" menu ( SIM Applications)
      2. Select "Settings
      Newer SIM Cards: Select Compatibility option and make sure "On" is selected
      Older SIM Cards: After selecting Settings:
      1. Agree with message by pressing "Yes"
      2. Dial digits "1101" and select "OK" (Screen will show "CC OptionX: ON" message)

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


      We strongly recommend you to watch very short video tutorials for iPhone that will help you to understand how to make calls, SMS and data on your OneSimCard iPhone.
      If your phone is not Jail-Broken, you still can use OneSimCard Assist app available from iTunes. This app will help you to dial numbers properly by correcting mis-dialed numbers and will allow easy access to OneSimCard functions like checking balance, recharging your SIM, activating discounts and others.

      These videos are available in the Help Menu of your OneSimCard Portal. You need to log in to your OneSimCard account first and then proceed to the Help Menu to be able to access these videos.

      Again, this is for older SIM Cards. Newer SIM cards do not require entering any codes in iPhone or other types of phones.
59. Rates and Cost Questions
    • Can I send an SMS to or from a Common Access Number or Personal Extra Number?

      You can't send SMS to a Common Access Number (CAN). Common Access Numbers and majority of Personal Extra Numbers are for Voice Calls only.

      We recommend that SMS senders use our free online SMS or email-to-SMS functions as described in the user manual and our FAQs.

       

      Note: US and Canada PEN can receive only actual mobile SMS from mobile phones. Alert and verification SMS sent from web sites like Google, Yahoo or your bank will not be delivered to US or Canada PENs due to the way these web sites send their messages. 

      If you require some alerts SMS sent from banks and other institutions, we offer special US-SMS Bank Verification PEN that will be able to receive SMS from mobile numbers as well as from institutions used for 2 step verification processes.

60. Rates and Cost Questions
    • Is there a way to send a SMS to a short code number?

      The SIM card does not offer SMS service to short code numbers

      OneSimCard offers special US Phone Numbers working with the SIM or even without SIM which are capable of receiving SMS from Short Codes, like those sent by Banks, Paypal and other institutions as well as replying to short codes SMS using 1SIM VOIP app.
