11. 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 two years. If you fail to make or receive at least one call every two years, 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.

12. 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.

13. OneSim VoIP
    • Can I used OneSim VoIP over the Internet Data offered by OneSimCard SIM? Will it save me anything?

      In countries where the cost of using mobile Internet Data is below 20 c/MB, the cost of using SIM VoIP over the data is comparable or smaller than the actual calling rate from the country.
      As a rule ot thumb, the SIM VoIP will use 1MB /Min of talk time. So if the cost of Data in the country is 10 c/MB, then 1 minute SIM VoIP call will cost you 12 cent /minute. You need to have a 3G connection in order for SIM VoIP to work this way.
14. How To Use Questions
    • How do I check my OneSimCard balance?

16. 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 15-59 cents 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 and Canada available since Jun 3rd, 2014. When replying from OneSimCard phone to the SMS received on USA or Canada SMS capable PEN, the main number of the SIM that starts with 372 will be displayed on the text receiver phone.


      You can also send a free SMS message to any OneSimCard customer from our web site or by sending email to 372XXXXXXXX@sms.onesimcard.com, 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.

17. 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.

18. How To Use Questions
    • How do I prevent the service from expiring?

      The OneSimCard phone number has no expiration, provided you made at least 1 call or send SMS once every two years.

      However, the funds on the SIM expire 10 months after your last recharge. The minimum recharge amount is $25. You can keep the balance from expiring by simply recharging at least once every 10 months. If you let your balance expire, then all you need to do to get the service up and running again is to log in and add funds to your SIM card.

20. OneSimCard General Service Questions
    • What phone numbers are included on the global SIM card?

      Starting April 19th, 2016, our OneSimCard international SIM card comes with two phone numbers: European (Estonia) and U.S. numbers. For Canada Customers it is European and Canadian numbers. For Australian customers it is European and Australia numbers and for UK customers it is Estonia and UK Mobile numbers.

      The primary European number is based in Estonia (country code +372). Estonia is a member of the European Union and one of the most high-tech and entrepreneurial societies in the world, especially when it comes to telecommunications. The world-famous program Skype was invented by Estonian developers.

      The Free 30 days U.S., Canada, Australia and UK numbers are randomly assigned and you can choose to assign the number when you activate your SIM card or at a later date. Once your free PEN is assigned, it will be active for 30 days unless renewed monthly or yearly for a small cost. If instead you would like to choose your own U.S. or Canada, Australia or UK area code or a Toll Free number, you can order this separately.
