Introduction: The Shadow of GSM in the Era of 5G
It is an invisible signal, almost forgotten, yet it still feeds entire sections of our digital daily lives. 2G, or GSM (Global System for Mobile communications), was born in the 90s to allow us to make calls and send SMS. In 2026, while we discuss millimetric latency and dizzying speeds with 5G, this "archaic" network is preparing to take its final bow.
For the general public, the announcement of the end of 2G may seem trivial. Who still uses a Nokia 3310 in 2026? However, Arcep and the operators (Orange, SFR, Bouygues Telecom, and Free) face a major technical and economic dilemma. Maintaining a 2G infrastructure is energy-expensive and occupies spectral frequencies that could be reallocated to more efficient technologies. But behind the apparent simplicity, the extinction of the 2G signal risks creating "blind spots" for millions of pieces of equipment.
What are the real stakes of this transition? Why do certain uses still resist so fiercely? A breakdown of a major infrastructural turning point for the French telecom landscape.
The 2G Paradox: Why is it Still Used?
While 4G and 5G dominate data traffic, 2G retains technical properties that its successors have not fully optimized for all use cases. Its simplicity is its strength.
1. Signal Range and Penetration
The 2G signal, using low frequencies, has a propagation capacity far superior to the high frequencies of 5G. In certain very isolated rural areas or in buildings with thick walls, 2G is sometimes the only signal capable of crossing obstacles to allow an emergency call or the sending of a simple SMS.
2. "Low-Cost" Internet of Things (IoT)
This is where the real critical point lies. Millions of connected objects (M2M - Machine to Machine) still operate on the 2G network. Why? Because GSM modules are extremely cheap and consume very little energy. These technologies are found in:
- Home and professional alarms: Many security systems use SMS to alert the owner in case of intrusion.
- Energy and water meters: Some old remote reading deployments rely on GSM.
- Payment terminals (POS): Although the transition to 4G is well underway, some old terminals in local shops still depend on 2G.
- Elevators: Emergency phones installed in elevator cabins are often 2G equipment.
Arcep Facing the Transition Headache
Arcep, the telecom regulator, is closely monitoring this timeline. The challenge is to avoid creating a brutal rupture that would leave users or businesses without service. The current strategy relies on a progressive incentive toward 4G and 5G, but the reality on the ground is complex.
The Cost of Replacement
For a company managing a fleet of 10,000 2G sensors, moving to 4G does not simply mean changing a plan, but physically replacing the hardware. This is a massive investment that slows down the transition.
Spectrum Management
The radio spectrum is a limited resource. By shutting down 2G, operators can free up frequency bands to strengthen 4G capacity or deploy new 5G slices. This is an indispensable gain in spectral efficiency to absorb the explosion of data traffic, notably with the rise of high-definition video and cloud gaming.
What Risks for the End User in 2026?
If you own a recent smartphone, you will probably feel no difference. However, certain profiles are directly exposed.
The Risk of "Loss of Service"
Imagine a user who keeps an old phone for reasons of simplicity or robustness. Overnight, the device will no longer pick up anything. Even more serious, SMS-based security systems could stop working, leaving homes unsupervised without the owners being informed.
The SMS Problem
Although SMS is supported by 4G and 5G (via SMS over IMS), some old equipment does not know how to "speak" this protocol. They only know how to send SMS via the classic GSM channel. If the 2G network disappears, these messages will never be delivered.
| Technology | Primary Use | Range | Energy Consumption | 2026 Status |
|---|---|---|---|---|
| 2G (GSM) | Voice / SMS / Simple IoT | Excellent | Very Low | Phasing out |
| 3G (UMTS) | Voice / Basic Data | Good | Medium | Already largely reduced |
| 4G (LTE) | Data / VoLTE | Medium | Medium | Current Standard |
| 5G | Ultra-Data / Low Latency | Short (high freq) | Variable | Massive deployment |
How to Anticipate the End of 2G?
To avoid unpleasant surprises, it is essential to audit your connected equipment.
For Individuals
- Check your alarms: Contact your installer to find out if your alarm panel uses a 2G GSM module. If so, request an update to a 4G module or an IP connection.
- Sort through your old devices: If you use an old phone as a backup, check if it is 4G compatible. If it is only 2G/3G compatible, it will soon become useless.
For Professionals
- M2M Fleet Inventory: List all equipment communicating via GSM. Priority should be given to critical systems (security, health, emergencies).
- Budget Planning: Replacing GSM modules is an operational cost that must be integrated now into 2026-2027 maintenance budgets.
Conclusion: Toward a "Full IP" World
The end of 2G marks the end of an era. It is the definitive transition from a world where voice and text were carried on dedicated channels (circuit switching) to a world where everything—absolutely everything—passes through the IP (Internet Protocol) protocol.
While this mutation is necessary to support innovation and network performance, it reminds us that technology leaves no one behind, but it imposes a constant rhythm of renewal. The challenge for Arcep and the operators will be to transform this technical shutdown into a fluid transition, without accidentally leaving an elevator or an alarm in digital silence.
The extinction of 2G is not just a question of frequencies; it is the final lock to be removed to make way for the era of hyper-connectivity. Stay vigilant about your equipment, because the signal itself will not give a warning before going dark.
