    • 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.
