SA regulator calls for symmetrical mobile termination rates

Article Image
South Africa's telecoms regulator has determined that mobile termination rates (MTRs) must become symmetrical within a year.

That's according to the Independent Communications Authority of South Africa (ICASA), which has completed a review of the call terminations regulations as it moves forward with pro-competitive conditions for licensees.

The consultation process started in the second quarter of 2021 and was concluded on March 30, 2022, with ICASA issuing determinations, which are meant to reinforce competition and good practice in setting termination rates and call charges.

MTRs are the fees operators pay each other to terminate voice calls made by subscribers on a different network.

Symmetrical rates are when all telcos pay the same MTR tariff per minute to each other while in the case of asymmetric MTRs the regulator decides that a group of telcos pay more or less according to the market’s conditions.

Usually, regulators go for lower MTRs for new entrants for either a few years following their launch or indefinitely until the regulation is reviewed. The latter was the case in South Africa. Asymmetry is intended to help smaller players and new entrants to reduce costs.

Market leaders supportive

The current call termination regulations were issued in 2014 and ICASA also conducted a review in 2018.

Key determinations include that licensees must charge cost-based pricing and that mobile termination rates will move to symmetry within a transitional period of 12 months while new licensees will qualify for asymmetry for a limited period of three years after entry into the market.

ICASA also maintains the separation between fixed and mobile termination rates.

Industry players Vodacom, MTN, Cell C, Telkom, FirstNet, Switchtel and ECN had the opportunity to share their views on ICASA's proposals in 2021.

Moving to symmetrical MTRs is supported by market leaders such as Vodacom and MTN. Their reasons include the fact that asymmetries sustained over time have not proven to be effective. They may also entrench inefficiencies in small operators who fare better staying small.

Telcos with smaller market shares see symmetrical MTRs as an obstacle for current and potential new small players, to continue to invest in the South African mobile market. At the same time, they feel like symmetry further entrenches Vodacom and MTN's long-standing dominant positions.

Telkom pushes back

As a mobile operator with a smaller market share, Telkom opposed the proposed removal of the MTR asymmetry combined with the retention of the existing fixed termination rate (FTR)-MTR differential.

Telkom feared that its net out-payments to Vodacom and MTN would increase substantially, while at the same time preventing the company from recovering the costs of calls terminated on its own networks.

Asymmetric MTR have been effective for over ten years in South Africa. While Cell C's subscriptions market share declined over this period, Telkom's mobile market share increased. However, Telkom's share remained below 5% until 2017 and the growth only accelerated and exceed 10% afterwards on the back of change in marketing strategy.

Hence, in the South African case, asymmetric MTRs have not proved successful in boosting market share. Mobile voice tariffs may have in the meantime become more competitive but there's been pressure from over-the-top (OTT) services and the decline is essentially for on-net calls.

Africa Green ICT: Lighting Up a Sustainable Continent

The ICT industry is the leading industry in the commitment to carbon neutrality, whose focus has shifted from setting ambitious targets to taking initiatives. The push for zero-carbon and for green energy development, it isn't just about CSR – it's also good for sustainable business.

The path to sustainable development requires green energy. Governments are looking at potential policy approaches to make green energy more widely available and affordable. Without sustainable energy, there will be no digital transformation and no chance of making Africa more economically competitive in the post-pandemic era.

Africa Green ICT Webinar 2022 will bring together ICT industry leaders and senior industrial analysts to provide insight, best practices and key learnings on how to achieve zero-carbon targets and practice green development in Africa.
