In any case mtn has such poor 3g and lte coverage that you cannot make voip calls successfully in most places. I have both an mtn and vodacom data card and travel lots. mtn data is always slow, usually on edge.QUOTE]
So true! Who cares about their exorbitant rates. VOIP will not work on their EDGE networks.
What happens in the case whereby the customer makes use of another vendors APN solution, which in part makes use of the MTN network. I am paying for my 2GB worth of data monthly, with no contractual agreement with MTN, yet I am using their network. From what I understand my vendor of choice has an agreement with MTN, therefore I would still get my 2GB without incurring additional costs as my vendor has not stipulated this?
MTN and Vodacom said that users are allowed to use voice over IP (VoIP) services on their networks, but that they reserve the right to change this in future.
MTN previously warned that its mobile broadband network may not be used to transfer or generate Voice over Internet Protocol (VoIP) traffic. The company further warned subscribers that VoIP traffic may be charged at R25 per megabyte (MB).
The MTN terms and conditions stated that “the MTN GPRS, GPRS+, EDGE or 3G technologies may not be used to transfer or generate Voice over Internet Protocol (VoIP) traffic”.
MTN however clarified the situation, explaining that these were their old Terms and Conditions (T&C) and that their subscribers are free to use VoIP services on their mobile data network.
“MTN does not block VoIP over our network. There are a number of MTN customers who do use VoIP services over our network and are charged at normal data rates,” said Mapula Bodibe, MTN’s general manager for consumer segments.
Vodacom also confirmed that their subscribers may use VoIP services on their data network without any fear of higher data prices or facing the risk of having their service discontinued.
snip.... In Thailand, for instance, the operators have an option where you can pay a lower rate if you dial a prefix before the number which switches your call to VOIP - the call quality is not as good, so it is a trade off, but a very popular option and I guarantee you that networks that don't offer innovative services around VOIP and data will bite the dust eventually.
