The Information and Communication Technologies Authority (ICTA) of Mauritius has officially published the binding timeline for the nationwide **3G network sunset**. Mobile network operators must fully decommission all legacy 3G infrastructure by the end of **2028** at the latest, driving transitions to high-capacity 4G LTE and 5G cellular systems.
Transition Guidelines and Ban on 3G Imports
To prevent the influx of obsolete hardware, the ICTA has urged market suppliers to immediately halt the importation of all 3G-only cellular devices. Newly imported cellular gateways, IoT terminals, and mobile handsets must support 4G or 5G bands to obtain type approval and clear Mauritian customs. This initiative is designed to free up vital sub-GHz spectrum for next-generation telecom networks.
New Spectrum Allocations (2300 MHz & 700 MHz)
Coinciding with the 3G sunset, the ICTA has issued key decisions to support modern network rollouts. The authority has opened the **2300–2400 MHz frequency band** for IMT-5G systems. This follows the opening of the **700 MHz band** for advanced testing and commercial deployments, ensuring operators have the required bandwidth to support high-density wireless services.
Compliance Implications for Exporters:
- Deprecate 3G-Only Modules: Redesign any products targeting Mauritius to utilize 4G LTE or 5G modules.
- Utilize Online Portals: Type approval applications must be submitted via the ICTA online web portal prior to shipment arrival.
- Licensed Importers Required: While foreign manufacturers can apply, a registered Mauritian dealer license holder is required to clear customs.
HertzWeg Insight:
"Sunsetting 3G networks is a logistical challenge for companies deploying long-lifecycle industrial IoT hardware. If you have legacy sensors deployed in Mauritius, transitioning your fleet to LTE-M or NB-IoT should be completed ahead of the 2028 deadline to prevent coverage loss."
