I am a resindent of United States . Today I found info about a VOIP service named MPINGI that allows to make unlimited calls to US. The requirement is to have a high speed internet connect > 128 Kbps. I saw that BSNL has a startup plan starting from 250 per month . It shows that the download / upload limit is 1 gb per month. Is this limit applicable for VOIP data packets? My parents just use this service for VOIP and will never hookup a computer to this connection. They will just connect a adapter to the modem.Thanks
