5G: Coverage and Plans

5G in France in 2026 is widely deployed in cities, with performance varying by frequency band: 3.5 GHz delivers true high-speed (100-500 Mbps average) in dense urban areas, while 700 MHz offers wider but lower-gain coverage. All four operators sell 5G plans; Free includes 5G in its main plan, others charge a small premium. Coverage maps published by ARCEP let you check before subscribing.

> **Key takeaways**

> - 5G launched commercially in France in late 2020 and is now widely available in cities.

> - Three frequency bands are used: 700 MHz (wide), 2100 MHz (intermediate), 3.5 GHz (true 5G).

> - Real-world 3.5 GHz speeds in 2026 average 100-500 Mbps - 5 to 20 times faster than 4G.

> - 5G plans are available from all operators; Free includes it in its main plan.

> - ANSES monitors health concerns; current evidence does not show health risks at exposure levels in France.

Where Is 5G in France?

Commercially launched in late 2020, 5G is progressively being deployed across French territory. All operators now offer 5G plans, but coverage and performance vary considerably by area. For more on telecommunications in France, explore our complete guides.

Different Frequency Bands

Not all 5G is equal. In France, three main bands are used:

700 MHz Band: Good building penetration and extended coverage, but limited speed gains compared to 4G.

2100 MHz Band: Intermediate performance, often "recycling" of 3G/4G frequencies.

3.5 GHz Band: "True" 5G with speeds that can exceed 1 Gbps. But coverage limited to dense urban areas.

Current Coverage

In Urban Areas

Major French cities (Paris, Lyon, Marseille, Bordeaux...) benefit from good 5G coverage, particularly in the 3.5 GHz band. Performance there is truly superior to 4G.

In Suburban and Rural Areas

5G coverage is more limited there. When it exists, it's often in the 700 MHz band with modest performance gains. Priority remains 4G deployment in white zones.

How to Check Coverage

ARCEP publishes 5G coverage maps by operator at monreseaumobile.arcep.fr. The ANFR (National Frequency Agency) maintains the authorized antenna site database. You can also consult operator websites for an estimate at your address.

Real Performance

Impressive Speeds... In Theory

5G can theoretically reach 10 Gbps. In practice, speeds observed in France are rather 100 to 500 Mbps in the 3.5 GHz band, which remains 5 to 20 times higher than 4G.

Reduced Latency

One of 5G's major advantages is reduced latency (response time). It can drop to 10-20 ms versus 30-50 ms on 4G. It's a significant gain for online gaming and real-time applications.

Stability

5G offers a more stable connection, especially in high-traffic areas (stadiums, shopping centers, transportation).

Should You Switch to 5G?

Concrete Advantages

Much faster downloads
Better HD/4K video streaming experience
Smoother video conferencing
More responsive mobile gaming
High-performance connection sharing

Current Limitations

Still uneven coverage
Requires a 5G-compatible smartphone
Higher battery consumption
Potential plan surcharge

For Whom Is It Really Useful?

5G is interesting if you're in a well-covered area AND have intensive uses (streaming, connection sharing, large downloads). For classic use (browsing, social networks, emails), 4G remains sufficient.

5G Plans

Prices

5G plans are not necessarily more expensive than 4G plans. Free, for example, offers 5G included in its 19.99 EUR plan. With other operators, expect 5 to 10 EUR more compared to an equivalent 4G plan.

What to Check

5G coverage in your usage areas
Included data volume (5G consumes more data because you use it more)
Your smartphone's compatibility

The Future of 5G

Deployment Continues

Operators continue their investments. 3.5 GHz band coverage should progressively extend to medium-sized cities and suburban areas.

New Uses

5G will enable new services: augmented reality, connected vehicles, massive IoT, advanced telemedicine. These applications will arrive progressively.

Conclusion

5G is a reality in France but its interest depends on your location and uses. Don't change plans just for 5G without verifying that it's available and performing well in your usual usage areas.

Frequently Asked Questions

Where is 5G available in France in 2026?

5G is widely available in major cities (Paris, Lyon, Marseille, Lille, Toulouse) on the 3.5 GHz band, and across most of metropolitan France on 700 MHz. ARCEP's coverage maps show current deployment per operator.

Is 5G faster than 4G in real conditions?

Yes, especially on the 3.5 GHz band where speeds typically reach 100-500 Mbps (versus 20-100 Mbps for 4G). On 700 MHz, the speed gain is modest. Latency also drops from 30-50 ms to 10-20 ms.

Are there proven health risks from 5G?

The French scientific agency ANSES concluded in its 2021 and updated 2024 reports that available evidence does not show a health risk at exposure levels measured in France. Studies continue.

Do I need a new phone for 5G?

Yes. Your smartphone must be 5G-compatible. iPhones from the 12 onwards, Samsung Galaxy S20 and later, Google Pixel 5 and later, and most mid-range and high-end Android phones from 2021 support 5G.

Are 5G plans more expensive than 4G?

Not necessarily. Free includes 5G in its 19.99 EUR plan. Other operators may charge 5-10 EUR more for 5G. Check ARCEP coverage before paying a premium.

Will 5G replace home fiber internet?

For most uses, fiber remains more stable and faster. However, fixed 5G boxes can be a strong alternative for areas without fiber, particularly in rural zones during the copper network shutdown.
