It is good, but there is an issue. – Funny Call: Phone Prank Calls Review

I do not know if VoiceMod is just corrupt, but when I watch an advertisement to give myself an extra 30 seconds for calling, the app just thanks me for selflessly donate to VoiceMod and does not say that the display gives any credit for ads. Beware that there is no free calling, it is paid for no matter what.
