101. Rates and Cost Questions
    • Is there a monthly or 30-day credit card spending limit for OneSimCard service?

      To reduce fraud, there is 30-day credit card spending limit set for each individual account. You will only be able to charge up to a certain amount during any 30-day period. You can see your current limit by logging in to your OneSimCard account and going to the Purchase History menu. There, you will find a Credit Card Authorization form available for download. If you would like to increase your monthly credit card spending limit, please download the Authorization form and submit it back to OneSimCard as instructed on the form.

      We strongly suggest that you set your monthly credit card limit before going overseas as dealing with the form on the road can be much more difficult.

    • 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.

    • 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.

    • Can I use Facetime and iMessage with eSIM?

      Yes, you can use Facetime and iMessage with eSIM, which now offers a mobile number ID.

So, when you are installing eSIM on iPhone, you can select the Primary service for Facetime and iMessage and then if your selected eSIM to be your primary data service, the communications will go over eSIM mobile data.
