61. OneSimCard General Service Questions
    • Can I move Personal Extra Numbers (PENs) between SIM cards in my account?

      Yes, you can move PENs within both private and corporate accounts. There is a small fee per PEN transfer which will be deducted from the SIM card the PEN is being moved to. If there is not enough money on this SIM, the fee will be deducted from the SIM the PEN is being moved from. If neither SIM card has enough balance, you’ll have an option to recharge. Transaction records will be posted under the History menu.

64. OneSimCard General Service Questions
    • Can I install my OneSimCard eSIM more then once?

      You can re-install the eSIM on the same phone up to 10 times if required. You can't move eSIM to another phone. It can be installed only on a single phone. If you need to install eSIM on another phone, please order a new eSIM. Balance and PEN(s) from the old eSIM can be moved to a new eSIM at your request.
65. Rates and Cost Questions
    • What is the cost to make calls from a OneSimCard phone to another OneSimCard phone?

      It depends on the country you're in when making the call. In many countries there is a special low rate of just $0.25/min to call another OneSimCard phone (only when dialing the other OneSimCard user's primary mobile number, not a Personal Extra Number). In other countries your cost will be our standard low outgoing call rate from that country.

      Example 1: two OneSimCard users are in Italy and one calls the other, the cost will be $0.25/min for the caller and free for the receiver.


      Visit our Rates & Coverage page and choose any country to view its current rates. Use the dropdown menus to see rates for calling to/from other countries.

      PLEASE NOTE: If you activate a discount call plan, the special rate to make OneSimCard-to-OneSimCard calls will not be available. You will be charged for those calls according to the discount call plan rate.

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

      Your OneSimCard global SIM card and European phone number will never expire as long as you make at least one call every 18 months. If you fail to make or receive at least one call every 18 months, your OneSimCard global SIM card and European phone number will expire and you will not be entitled to a refund even if at the time of expiration your account had a positive balance.

      However, the funds on the SIM card will expire 10 months from your last recharge and will not be refunded to you. The minimum recharge amount is $25. By simply recharging at least once every 10 months your balance will roll over. If your balance does expire, it will not be refunded to you but all you need to do to get the service working again is to log in and add funds to your SIM card. If you set up the automatic recharge, it will be canceled if you allow the funds to expire, so you will need to set automatic recharge up again once you recharge your balance.

67. OneSimCard Rentals
    • When do you consider the rental package as having been returned?

      You should ship the package back to us through the US Postal service using the label and envelope that came in your original package. 

      As of March 5, 2018, all rentals come with a prepaid USPS Priority Mail return label. Simply attach it to the provided return envelope with your rentals inside and drop it off at the nearest post office. It’s that easy!

      The post office will scan the label. The date the package is scanned is considered the rental's return date. Thus you will not be charged rental fees for the days after the package is scanned to be shipped back to OneSimCard.

      Besides this, generally, OneSimCard can be used on any cruise ship when the ship is close enough to shore so the cell tower signal can be picked up by the phone. The ship should be within at least 1 mile from the coast for your cell phone to pick up a signal. Service will work only when the phone is close to a country where OneSimCard provides international roaming service. Rates are the same as if a call was made from the shore of the country you are near.

70. 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.
