What do I need to consider when the 2G and 3G networks are phased out, and what does it mean?

The 2G network will be shut down between 2025 – 2027 while the 3G network has already started to be phased out and will be decommissioned by the end of 2025. This technology shift is also happening abroad, which means that it is not certain that the mobile phone will work if you travel abroad, at least not older models, which only support 2G and/or 3G.

The shutdown means that all voice and data communication via the 2G and 3G networks will cease, which means that devices that only work with that technology will not work at all for calls, SMS, and surfing, not even for emergency calls. This phase-out affects everyone, both companies and individuals, who use equipment connected to the 2G and 3G networks. It can involve everything from alarms, card terminals, and nodes in the power grid to older mobile phones and emergency phones in elevators. Therefore, find out if this applies to you, your organization, or company and switch to devices that work with 4G and 5G.

New technology such as 4G and 5G means higher speeds and more stable connections than 2G and 3G. The modern networks are also safer and more robust and provide better call quality. To be able to offer new services over 4G and 5G, more frequency space is needed. The shutdown of 2G and 3G frees up space for the newer technologies. More modern technology can also contribute to a more climate-smart society as the new networks are up to five times more energy-efficient than the older ones.

As a consumer, you need to check that your mobile phone and other equipment such as routers and alarms can be used in the 4G or 5G networks. If you have an older mobile phone or router, there is a risk that it will stop working. Search online or in the manual if you still have it and look for, for example, GSM, 2G, 3G, 4G (alternatively LTE), and 5G. If only GSM, 2G, and/or 3G are available, the equipment is likely not compatible with the new networks.

It is also good if you check your subscriptions by contacting your operator. All four major operators’ subscriptions should be upgraded to handle 4G/5G. The operators usually have good tips on how to check your subscription and tips if, for example, you need to factory reset for everything to work.
If you are going to buy new electronic equipment that communicates via the mobile network, it is important to investigate whether there is support for 4G/5G. Look in the description of the equipment. If it only says GSM, 3G, or 2G, there is a high risk that it will not work with the new networks. If a company sells goods that lack support for 4G/5G without clearly informing about it, the product is considered defective according to the Consumer Agency’s assessment. Then you should complain about the defect, and the company is obliged to rectify the problem.
