2G/3G network sunset

More and more mobile operators worldwide are taking steps to phase out their 2G and 3G networks. In this article, we provide an overview of the most recent network sunset updates, including all changes and additions implemented over the past three months.

This information is particularly relevant for organizations using IoT solutions or legacy devices that still depend on 2G and/or 3G connectivity.

Why is this important for IoT?

If your current or planned deployments still rely on 2G or 3G connectivity, a network sunset may lead to:

• Loss of connectivity

• Increased operational pressure (urgent migrations, additional field visits)

• Unexpected costs (hardware replacement, recertification)

At the same time, 2G and 3G remain attractive in certain situations due to their lower costs and limited bandwidth consumption, which is sufficient for many IoT applications. This is precisely why timely insight and planning are crucial.

What do we recommend?

• Map which devices are still using 2G and/or 3G, broken down by country and operator.
• Start migrating to 4G/5G or LTE-M / NB-IoT well ahead of the announced sunset dates.
• Pay extra attention to operators with a “Planned” status that have not yet communicated a concrete date.
