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
