We are here to help you get answers to your questions about OneSimCard phones and services.
Are there any additional roaming charges?
There are NO additional roaming charges. The rates you see listed on our Rates & Coverage page are the only rates you will be charged when making or receiving calls on your OneSimCard enabled cell phone. This is true for using regular cellular voice or 1SIM VoIP App.Can I use 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 less than the actual calling rate from the country.
As a rule of 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 cents /minute. You need to have a 3G connection in order for SIM VoIP to work this way.Â
Can I use Facetime, WhatsApp, Telegram, Discord, iMessage, and other messaging Apps with eSIM?
For DataMax eSIM, you can use these Apps as you already do. Please ensure your messaging account is already setup with your primary carrier’s phone number because you cannot sign up for these services with the DataMax eSIM number.
Additionally, the eSIM data service can be used for the actual data part of your communications. So, when you are installing eSIM on phone, 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.
