The Electronic Communications Office of Iceland (ECOI) monitors the phase-out of older mobile networks (2G and 3G)

The Electronic Communications Office of Iceland (ECOI) closely monitors the ongoing phase-out of older mobile network systems (2G and 3G) now being carried out by the three Icelandic telecommunications operators that provide mobile services: Nova, Síminn, and Sýn.

It is important to note that this phase-out represents a positive development overall. As 4G and 5G networks take over as the backbone of mobile communications, Iceland’s mobile infrastructure will become simpler, more efficient, and more secure. The older systems have become obsolete, and manufacturers are discontinuing support for the equipment. This alone poses potential long-term security risks for electronic communications.

It should also be emphasized that the decision to phase out these legacy systems rests entirely with the telecommunications companies. Since 2022, ECOI has been involved in this process with a focus on safeguarding the interests of mobile service consumers. An open consultation was launched in early 2023 to inform users about the upcoming changes and to ensure that sufficient time was available to replace or upgrade essential equipment before the networks were shut down.

ECOI also included specific requirements in the frequency licenses of the operators to ensure that the phase-out of 2G and 3G networks would not result in reduced service quality or coverage. Coverage obligations are based on a defined percentage of the population. In addition, ECOI has issued several public announcements to keep consumers informed and to provide guidance on how to prepare for the transition. 
A dedicated website has been set up to collect feedback and complaints, as well as to offer instructions on how users — independently or in cooperation with their service providers — can improve their mobile signal reception, both indoors and outdoors.

With less than three months remaining until the final shutdown dates, ECOI considers it timely to update the public on the project’s progress and its current status.

Nova and Sýn (Vodafone) have already completed the phase-out of their 2G (GSM) networks and are nearing completion of the 3G shutdown. As of this writing, ECOI has received very few comments or complaints regarding service quality from customers of these two companies. This indicates that the services provided through their 4G and 5G networks are comparable to — or even better than — those offered by the older systems.

Síminn, on the other hand, is at an earlier stage in its phase-out process, and therefore fewer changes have occurred within its network so far. The final months of the year will see increased activity as Síminn proceeds with its shutdown plans. ECOI has no reason to expect different results from Síminn than from Nova and Sýn, as all three companies have invested significant effort in preparation and customer communication. However, as with any large-scale technical transition, some issues may arise during the final stages.

ECOI emphasizes that mobile users are encouraged to use the agency’s website to submit feedback or complaints if they experience reduced service quality. All reports are taken seriously and carefully reviewed; ECOI conducts inspections and measurements as needed and communicates findings to the relevant operator when appropriate. Since some of the reports received — even those made through the media — have proven unrelated to the network phase-out, ECOI urges consumers and journalists alike to seek clarification directly from ECOI or the operators before drawing conclusions.

ECOI reiterates the importance of ensuring that all equipment — including mobile phones, alarm systems, and other devices that rely on mobile networks — is ready for the new era of communications. The older 2G and 3G systems are disappearing, while 4G and 5G offer faster, safer, and more stable connectivity.

Institutions and businesses, particularly those operating critical or safety-related equipment, are also reminded to confirm that all systems and devices using mobile connectivity are compatible with the latest technologies. The shutdown of 2G and 3G networks is an inevitable step toward improving the long-term security and stability of Iceland’s communications infrastructure.

Take action now — before the older networks are turned off — to ensure that essential communications, systems, and services remain uninterrupted as the future takes over.
