The 2G and 3G shutdown – how it affects your business

What does it mean for your business?

If you have devices that only support 2G or 3G and use Tele2, Telenor or Tre, they have already lost their connection. The fact that an older device still works does not mean it is future-proof. It is most likely running on Telia's 2G network, in which case it will stop working at the latest by the end of 2027.

This also applies to mobile phones. Following a decision by PTS, Tele2, Telenor and Tre have since 2 February 2026 been blocking phones that cannot make emergency calls to 112 over 4G. The decision does not apply to Telia's customers.

IoT and M2M – the final deadline is 2027

Many connected installations were built for 2G. The modules were cheap and low-power, and the 2G networks covered almost the entire country. The installations that have survived so far are often in places where nobody checks on them every day, for example:

• alarm and monitoring equipment
• older routers and modems for mobile broadband
• remote reading of meters and sensors
• control of properties and heat pumps
• payment terminals and vending machines
• trackers and fleet management
• emergency phones in elevators and access control systems

A replacement takes time. It usually requires new hardware, an installer on site and new subscriptions. The closer we get to the end of 2027, the greater the demand for both installers and equipment. So start with the installations that are hardest to reach and most important for your business.

Checklist ahead of 2027

1. Make an inventory of all connected devices and note the model, modem and which networks they support.
2. Find out which ones run on 2G today. You can see this in the device status or in your connectivity portal. Devices that only support 2G will stop working in 2027. Devices that support 4G but are still on 2G often have weak 4G coverage at the location and may need a better antenna or a different placement.
3. Prioritise based on how important the device is for your business and how difficult it is to access.
4. Choose a replacement. 4G (LTE Cat 1/Cat 4) suits most needs. LTE-M and NB-IoT suit battery-powered devices that send small amounts of data.
5. Check the subscription. The SIM card and subscription must support the technology in the new device.
6. Check mobile phones and devices with voice functions, such as elevator phones and door entry systems. All of them must support 4G/5G and VoLTE (calls over 4G), and mobile phones must also support emergency calls to 112 over 4G.
7. Make a schedule so that the replacements are completed with a good margin before the end of 2027.

Why are the networks being shut down?

2G and 3G use frequencies that are of greater benefit in 4G and 5G, with higher capacity, faster data transfer and a more stable connection. The operators have phased out the networks gradually to have time to detect and fix problems. The same transition is under way in many other countries.

Frequently asked questions

My device still works. Do I need to do anything?

Yes, if it only supports 2G. In that case it is very likely connected to Telia's 2G network and will stop working at the latest by the end of 2027.

Does this apply to social care alarms?

Yes. Social care alarms that only support 2G will work until the end of 2027, but only if they run on Telia's network and have coverage there. Responsibility for modernising municipal social care alarms lies with the municipalities.

What is VoLTE?

VoLTE (Voice over LTE) means that calls are made over the 4G network. Without VoLTE, a phone cannot make calls when 2G and 3G are unavailable, even if it supports 4G for data.

Where can I find more information?

At PTS and at Byt nät nu (bytnat.nu).
