Mobile operators are appealing to the department of justice to extend the deadline of the Regulation of Interception and Communication Act (Rica), says Vodacom Group CEO Pieter Uys. The act requires that all telecommunications providers and Internet providers register customer details, including their ID numbers and physical addresses. The process has to be completed by January next year, after which unregistered customers have to be cut off from the networks.

In spite of a solid performance in mobile data, SA’s largest telecommunications operator, Vodacom, has reported flat group revenue growth of 3% in the first quarter of its 2011 financial year.

Want to phone someone on Vodacom? Rather than dialling “082”, you may soon have to dial “882” instead. Draft regulations governing the phone numbering scheme SA uses could mean that every phone number in the country will have to change.

The spectrum, in the 2,6GHz and 3,5GHz bands, is ideally suited to providing the next generation of wireless broadband services.

Tired of cellphone spam and unwanted SMS subscription services? Here’s your chance to do something about it. Well, kind of.

When I arrived at Jeremy Ord’s office last Friday — the day after news that the group he cofounded and now chairs, Dimension Data, was being bought out for R24,4bn by a Japanese corporate giant — he was looking relaxed. Having just flown back from London that morning, Ord appeared a little tired but entirely laid-back in jeans, takkies and an old jumper.
