Econet Wireless has launched a comprehensive per second billing system which applies across networks and international calls. The service will be offered to both prepaid and contract customers.

Econet upgraded its network to cope with the rise in traffic volumes anticipated from the introduction of per second billing.

"The cost of making calls will be cheaper, so traffic volumes will increase. We had to first clear issues of capacity before opening up to per second billing," said Econet's CEO Douglas Mboweni.
