Mobile networks in Sweden are entering a technological transition. Over the coming years, 2G (GSM) and 3G will be gradually decommissioned. But what does that actually mean for businesses, organisations and operations that rely on these technologies for their communications?
For some organisations it will require only minor adjustments. For others it could become critical, demanding a full review of their operational environment. This article explains what the shutdown of 2G and 3G means and how to prepare for a future based on 4G and 5G. There is urgency if you do not yet have a plan, but there is still a limited window of time to act.
Timeline: when will the networks close?
All major operators in Sweden have announced plans to shut down their 3G networks in 2025. At the same time 2G networks will be phased out — for Telia as late as 2027, while other operators are closing down in 2025. This means many connected products and services that work fine today risk becoming unusable unless action is taken.
Why you need to act now
2G and 3G networks have been the backbone of Swedish IoT and M2M communication for a long time. However, the technology is outdated, consumes more energy than newer standards, and the frequency spectrum it occupies is needed to expand 4G and 5G. At the same time 5G is emerging, offering much higher capacity, lower latency and greater potential for future-proof solutions.
To ensure continuous operation and modernise infrastructure, it is important to begin the migration well ahead of shutdown dates.
Impact on businesses and systems
GSM and 3G are still used across many sectors in Sweden. Examples include:
- Alarm and access control systems
- Monitoring and remote control
- SCADA systems and industrial control
- Elevator alarms and operational alerts
Many of these systems have been in operation for many years — stable, proven and often without an obvious need for upgrades. Now is the time to take action.
A sensible first step is to find out whether the equipment you use today is compatible with newer networks or if a full replacement is required.
Choose a reliable partner
Specialised partners can help you navigate this transition. Experienced vendors have carried out many migrations from GSM and 3G to modern alternatives. The recommendation is straightforward: start early. A good partner will help you select the right technology, choose appropriate products and plan a smooth transition.
To further explore the topic, refer to vendor resources and technical blogs that discuss migration strategies and preparedness.
By acting now you minimise the risk of operational interruptions and gain the opportunity to modernise your communications infrastructure.
📌 Checklist – How to prepare for the 2G/3G shutdown
- Identify devices and services that use GSM/3G
- Contact suppliers to clarify current status and support options
- Plan migration paths to 4G or 5G
- Allocate budget for upgrades well in advance
