The Future of Mobile Connectivity in Spain: Transitioning from 2G and 3G Networks
Mobile connectivity is rapidly evolving, creating a pressing need to optimize the available radio spectrum. The Spanish Government has initiated a process aimed at discontinuing 2G and 3G networks. These outdated technologies have been in use for over two decades, and maintaining them poses operational, energy, and security challenges.
The Countdown Begins
The Ministry for Digital Transformation has launched a public consultation, open until January 20, 2026, to gather input from mobile operators, government bodies, and affected sectors. The goal is to create a well-planned roadmap for transitioning away from these legacy networks without leaving any users stranded. The focus is on ensuring continuity of service to end customers while managing the change smoothly.
Why Is This Transition Necessary?
Keeping 2G and 3G networks running is becoming increasingly unsustainable. These older systems consume more energy and have greater security vulnerabilities. They occupy valuable radio spectrum, particularly in the 900 and 2,100 MHz bands, that could be more effectively utilized for expanding 4G and 5G networks. As all European countries are taking similar steps, it highlights a trend toward modernity and efficiency in mobile communications.
Impacted Sectors
Despite the prevalence of modern mobile technologies, many critical devices still rely on 2G and 3G systems. For example:
- Elevators: Spain has over 1.1 million elevators operating, many of which are over 20 years old and depend on 2G for emergency communications. If the network goes down, disabled elevators could leave people trapped without a way to call for help.
- eCall Systems in Vehicles: These systems, which automatically call emergency services in the event of an accident, are required by law but many vehicles produced recently still utilize 2G technology.
- Telecare Services: Devices that elderly individuals use to request urgent help primarily rely on 2G. While some systems are being updated, many still function on outdated technology.
- Rural Payment Terminals: In remote areas, where coverage is limited, 2G remains the most feasible option for processing electronic payments.
Critical Services at Stake
The migration process is crucial for essential services like the 112 emergency line and eCall systems. Both must transition to 4G-compatible technologies like VoLTE (Voice over LTE). The government is keen on understanding how operators plan this transition and what quality measures will be implemented, ensuring that critical services remain operational during this period.
The M2M and IoT Landscape
In Spain, there are approximately 20 million active machine-to-machine (M2M) lines that also depend on 2G and 3G. These include smart meters and fleet management systems. The Ministry is actively looking for operators to provide data on device identification and plans for transitions to more modern technologies.
Challenges for Mobile Virtual Network Operators (MVNOs)
MVNOs rely on large operators’ networks. If 2G and 3G networks are turned off prematurely, without transitioning to VoLTE, many virtual operators could be left unable to provide voice services to their customers. This aspect has been noted in the public consultation, emphasizing the need for coordinated efforts and clear timelines.
Facing the Challenges of Roaming
Traveling users could face significant issues if their devices don’t support VoLTE, as they would be unable to make calls if 2G and 3G networks are down. The government has urged operators to resolve roaming issues and establish effective bilateral agreements.
Looking Ahead
While there are no set timelines for the shutdown, it is inevitable. Currently, 3G is almost entirely phased out, while 2G is expected to remain operational until at least 2030 due to the critical services reliant on it. Following the public consultation’s closure in January 2026, the government will analyze feedback and outline the next steps, potentially forming a dedicated working group to oversee the transition.
In conclusion, while the transition from 2G and 3G to more advanced networks is a complex and significant process, it is essential for the future of mobile connectivity in Spain. With careful planning and coordination among stakeholders, it’s possible to ensure a smoother transition that keeps all users connected.
