Why 2G still matters as 3G disappears

By the end of 2025, most UK networks will have shut down their 3G services to free up spectrum for newer technologies. This shift is designed to improve high-speed internet access, vital for powering the businesses of today, especially in a remote working world we now live in. 

However, many devices and critical applications still rely on 2G and 3G networks. While 4G and 5G represent the future, not everyone can—or should—immediately transition.

At Connection Solutions, we believe communication technologies should be fit for purpose. That’s why we work closely with our technology partner, Nextivity, to balance the latest innovations with the real-world needs of users. Instead of focusing solely on progress, we prioritise tailored solutions that serve our customers' specific requirements.

The Lasting Role of 2G 

Despite the gradual phase-out of older networks, 2G remains essential for several key applications, including:

• Emergency and Safety Devices: Many lone worker safety systems, personal alarms, and emergency response units still operate on 2G. These devices require reliable voice and SMS capabilities rather than high-speed data.

‍

• Basic Mobile Phones: Many individuals, including older adults and those in digital-minimalist communities, continue to rely on 2G phones for essential communication. Parents also opt for these devices for children to ensure connectivity without social media or internet distractions.

‍

• Infrastructure and IoT Devices: A wide range of smart meters, tracking devices, and remote monitoring systems still use 2G for its low power consumption and minimal data transmission requirements. In remote areas where newer networks may be unavailable, 2G remains a critical backup.

‍

• Battery Efficiency: Compared to 4G and 5G, 2G devices consume significantly less power. This makes them ideal for applications that require long-lasting battery life, such as GPS trackers and environmental sensors.

Navigating the Transition from 3G

While all UK networks are retiring 3G, 2G will remain available until at least the end of the decade. However, users on Three’s network—where no 2G fallback exists—will need to upgrade immediately. For those on other networks, 2G provides an ongoing safety net for low-bandwidth applications.

At Connection Solutions, we understand that connectivity isn’t one-size-fits-all. That’s why we’ve worked with Nextivity to enhance their software, ensuring our solutions support 2G and 3G where needed while also boosting 4G and 5G coverage. Whether you require basic voice communication, cutting-edge connectivity, or a hybrid solution, we have the expertise to design a system that works for you.

As the industry evolves, we remain committed to keeping you connected in a way that best suits your needs. If you need a tailored connectivity solution, get in touch with us today.
