Upgrading to 4G: Ensuring a Smooth Transition for Industry Users

Jul 28, 2023 | Industry News

As technology advances, so must our infrastructure and devices. With Singapore’s IMDA announcing the cessation of 3G networks from July 31, 2024, it has become crucial for industry users to upgrade their 3G modems and 3G SMS gateways to 4G models. This move is driven by the necessity to allocate more bandwidth to accommodate the rapid growth of 5G networks. While this transition may seem straightforward for normal consumers, it poses a significant challenge for industry users who rely on 3G networks for critical SMS alerts and notifications.
