Vodafone and Cognatel would/should have checked out the business model etc before agreeing to supply 50k sims and airtime?
"Dispute over network software led to abrupt closure of network yesterday evening (March 20)
Ovivo Mobile was terminated by MVNA Cognatel following an alleged dispute over network software that would have allowed the MVNO to uniquely identify each user, Mobile News understands.
It is believed that Cognatel was contractually
obliged to deliver the software but had failed to do so.
Uniquely identifying each user was essential to the operator’s service which provided free airtime, texts and data in exhange for agreeing to being targeted by marketing materials.
Furthermore, it also understood that Ovivo Mobile had been withholding cash from the Vodafone MVNA as part of the dispute and it was this that led to the plug being pulled at short notice yesterday."
