MTN has announced it will shut down its 3G network by 31 December 2025, accelerating the migration to more advanced 4G and 5G technologies. This move comes a year ahead of its original plan and follows a successful pilot project in Cape Town aimed at transitioning customers from legacy networks.

“In September 2022, the Department of Communications and Digital Technologies signaled its intention to phase out 2G and 3G networks,” MTN stated in a letter to customers who participated in the pilot. “While this transition will impact users, we are committed to ensuring minimal disruption and a seamless migration process.”

A Phased Transition from Legacy Networks

MTN first informed affected customers about the pilot project in January 2024. The initiative was conducted in select Cape Town areas, including Durbanville, Greater Melkbosstrand, and Milnerton Bloubergstrand. The goal was to test the migration process before rolling it out on a national scale.

With the pilot deemed a success, MTN has now set its sights on a phased nationwide migration. “We are actively transitioning customers from legacy 2G and 3G networks to 4G and 5G,” said an MTN spokesperson. “This is not just about shutting down older networks—it’s about delivering a faster, more efficient, and future-ready mobile experience.”

MTN is also evaluating a timeline for the eventual switch-off of 2G services, with further announcements expected in due course.

Government’s Role and Industry Collaboration

While MTN is pressing ahead with its transition plans, South Africa’s government has taken a more measured approach. The Independent Communications Authority of South Africa (Icasa) is currently conducting an economic impact assessment to ensure the shutdown does not leave rural or underserved communities behind.

Communications Minister Solly Malatsi recently told Parliament that the government would only proceed with the full phase-out once the assessment is complete. “We need to make sure we don’t cut off connectivity for those in areas where 4G and 5G networks are still not widely available,” he said.

One major hurdle to the transition has been the affordability of 4G and 5G devices. While Vodacom and MTN have launched budget-friendly options, mobile operators remain cautious about setting rigid deadlines.

Pushing for Affordable 4G and 5G Devices

To address accessibility concerns, Vodacom introduced the Mobicel S4 in September 2024, a cloud-based 4G phone priced at just R199. MTN followed with the Icon 5G in November 2024, offering a more affordable entry point to 5G with a 6.6-inch display, 128GB of storage, a 50MP primary camera, and a 5,000mAh battery—all for R2,499.

Government intervention may also help drive affordability. Minister Malatsi has proposed working with the National Treasury to remove ad valorem taxes on entry-level smartphones. “We’re not suggesting scrapping all luxury taxes on smart devices, but setting a threshold that makes basic 4G and 5G phones more affordable,” he explained.

A Bold Step Toward the Future

MTN’s accelerated 3G shutdown marks a significant milestone in South Africa’s digital transformation. While challenges remain, including ensuring affordable devices and broad network coverage, the shift toward faster, more reliable connectivity is well underway.

With a phased approach, industry collaboration, and a commitment to minimizing disruptions, South Africa is taking firm steps toward a future powered by advanced mobile networks. As MTN puts it, “We’re not just switching off 3G—we’re making way for something better.”
