61. 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.

    • Does voicemail work with OneSim VoIP?

      Yes. If you are not available to answer the OneSim VoIP call or if the OneSim VoIP app is turned off, the call will be routed through our standard roaming network. If the call is not answered it will be sent to your OneSimCard voicemail box. 

      NOTE: Voicemail is not available for DataMax or DataMax eSIM cards with OneSim VoIP.

    • Can I install my OneSimCard eSIM more than once?

      You can re-install the eSIM World and Asiana on the same phone up to 10 times. These eSIMs can be installed only on one device. Once installed, it's not possible move that eSIM to another device. 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.
      For DataMax eSIM you can re-install the eSIM 3 more times and this eSIM can be installed in more than one device, but must be deleted off the previous device first. The DataMax can only be installed a TOTAL of 4 times.
64. Rates and Cost Questions

    • Does calling a mobile phone cost more than calling a landline?

      It does not cost more to dial an international mobile number using OneSimCard service on traditional cellular connections. You will receive the same very low per minute rate whether calling to a mobile phone or to a land line. 

       

      For OneSim VoIP, the cost of calling Mobile numbers is typically higher than calling landlines, but this method is still less than traditional voice calls in most countries..


      You can find all rates listed on our Rates & Coverage page.

    • Is there any additional cost to create a OneSim VoIP account?

      There is no additional cost except for the fact that you need to have a compatible Personal Extra Number (PEN) active on your SIM card.
66. 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.

    • How do I top up my data with eSIM?

      There are two ways you can do this:

      1. For eSIM World you can use the 1SIM eSIM app.
      2. From your mobile go to ma.onesimcard.com. This provides the access to your free  OneSimCard mini account. Free means that there is no need to have the SIM balance or data package on the SIM to be able to access this page in over 110 countries. Log in to your account and activate a new data package.

        2. From any computer log in to your on-line account at OneSimCard.com to order a data package. 

      Simply go onto your web account or eSIM app and purchase a new data package appropriate to your travel needs.

    • Do I need to have a OneSimCard SIM card installed in my phone to use OneSim VoIP?

69. OneSim VoIP

    • How do I know if the Personal Extra Number (PEN) I currently have is OneSim VoIP compatible?

      Log in to your OneSimCard account, go to the My Sim Cards menu and scroll down. If your PEN is VoIP compatible you will see an option to create a OneSim VoIP account. At this time all OneSimCard PENs are SIM VOIP capable except for UK Mobile numbers.
70. OneSim VoIP

    • I can make calls through OneSim VoIP. However incoming calls are going through my roaming SIM. What's wrong?

      If your incoming calls are not being routed through the OneSim VoIP app then you are either not connected to Wi-Fi or the OneSim VoIP app is not active.

      Please make sure to check your phone's sleep settings, as they are usually preset to have Wi-Fi turn off when the phone enters sleep mode. To prevent this and to keep OneSim VoIP active for incoming calls, find the settings in your phone and set it so Wi-Fi does not turn off when the phone enters sleep mode.

      Note: if the OneSim VoIP logo on the top of your phone display is gray then you will not be able to receive calls through the application. When the logo is yellow that means you are connected and can receive calls through OneSim VoIP.
