The Independent Communications Authority of South Africa (Icasa) has gazetted a notice that it intends to regulate how telcos let unused data expire.
The regulator aims to amend the End-user and Subscriber Service Charter Regulations.
This will change the way telcos bill for out-of-bundle data, and how they allow unused data to expire.
Currently, most data bundles expire after 30 days, regardless of whether the allocated amount has been used or not.
Icasa proposes that data bundles from 1 Gb to 5Gb should remain valid for 90 days; while 20Gb and higher bundles should be valid for 24 months.
Users would also be able to roll over unused data during the contract term.
