What is 5G and do you actually need it?

5G is the fifth generation of mobile networks, standardised by 3GPP. Compared with 4G it brings three improvements: higher peak speeds on the 3.5 GHz band, lower median latency, and more capacity in dense areas. France launched commercial 5G in November 2020, after ARCEP auctioned 310 MHz of 3.5 GHz spectrum to the four national operators (Orange, SFR, Bouygues Telecom, Free Mobile).

The honest answer for most people: you will not notice a dramatic difference for everyday browsing, social media or HD streaming. 4G+ handles those tasks well. Where 5G actually helps:

  • Crowded places. Stadiums, festivals, busy train stations. 5G handles thousands of simultaneous connections better than 4G.
  • Low-latency apps. Cloud gaming, video calls and real-time collaboration feel smoother.
  • Home internet alternative. Where fibre has not reached your address, a fixed 5G box can deliver solid speeds.
  • Large transfers. A 2 GB file that takes a few minutes on 4G can finish in seconds on 3.5 GHz 5G.
  • Industrial IoT. Private 5G networks, automated logistics, predictive maintenance.

If your 4G connection is fine and you are not in a coverage-poor area, there is no rush. Most 5G plans cost the same as 4G now anyway, so you may end up on 5G without paying extra.

True 5G (3.5 GHz) vs 5G DSS: the real difference

Not every "5G" antenna delivers the same performance. Two approaches coexist in France.

5G on 3.5 GHz ("true" 5G)

This is the dedicated band auctioned by ARCEP in November 2020. Operators paid between 350 and 730 million euros for 50 to 90 MHz each. Real-world downlink speeds typically range from 200 to 800 Mbps, with peaks of 1 to 2 Gbps under favourable conditions. Each cell covers a shorter distance than low-band 5G, which is why operators have to densify the network in urban areas.

5G DSS (Dynamic Spectrum Sharing)

DSS reuses existing 4G bands (often 700 MHz or 2.1 GHz) by dynamically sharing capacity between 4G and 5G on the same block of spectrum. The upside: very fast wide-area coverage, including rural areas, without waiting for 3.5 GHz densification. The downside: speeds stay close to 4G+, usually 100 to 300 Mbps. Your phone still displays "5G".

In practice: a 5G icon does not guarantee gigabit speeds. The band you connect to depends on the nearest antenna, network load and your device. ARCEP's coverage map now separates 5G on 3.5 GHz from 5G on other bands, which makes the comparison fairer.

Frequency bands ARCEP has allocated

ARCEP has structured 5G deployment around four main bands, each with a different profile.

700 MHz and 2.1 GHz – coverage layer

Low-band frequencies that travel long distances and penetrate buildings well. Historically 4G bands, often reused for 5G via DSS. They let operators show wide population coverage, including rural areas, even if the user experience stays close to 4G+.

3.5 GHz (3.4–3.8 GHz) – the core of 5G

The technical core of 5G in France. 310 MHz auctioned to four operators in November 2020. An extension in 3,410–3,490 MHz becomes available across mainland France from 25 July 2026, adding capacity. Real-world speeds are significantly above 4G, which is why operators concentrate their urban investment here.

26 GHz (mmWave) – targeted use cases

Millimetre waves: very high speeds but short range (a few hundred metres) and poor indoor penetration. In France, deployment goes through ARCEP calls for tenders for industrial uses, transport hubs and pilot sites. For consumers it remains marginal in 2026 and is not enabled on mainstream plans.

Deployment: what ARCEP and ANFR report

ARCEP publishes a quarterly mobile observatory; ANFR publishes a monthly dashboard of authorised sites. As of early 2026, the two sources converge on the following orders of magnitude.

  • More than 54,000 authorised 5G sites (all bands combined) according to ANFR.
  • Roughly 47,000 operational sites: the gap covers antennas authorised but not yet in service.
  • More than 80% of the French population covered by at least one 5G operator, per ARCEP.
  • Geographic coverage is more uneven: dense urban areas are well served on 3.5 GHz, some valleys and rural areas are still 4G-only or 5G DSS-only.

The 2020 licences also require coverage of priority transport routes (motorways, high-speed rail lines) and identified rural zones, on a schedule monitored by ARCEP. The regulator can issue sanctions for non-compliance.

Coverage per operator: how to read the figures

Rather than ranking operators commercially, ARCEP publishes for each one: the number of 5G sites in service, the number of 5G sites on 3.5 GHz, and population coverage by band. These data are available on the mobile observatory and on monreseaumobile.arcep.fr.

Differences between the four national operators come mainly from:

  • Share of 5G on 3.5 GHz vs DSS: some operators densified 3.5 GHz in metropolitan areas faster, others prioritised wide 700 MHz / DSS coverage.
  • Deployment pace: the ARCEP observatory tracks net additions of sites quarter by quarter. The pace has accelerated since 2023.

For a like-for-like comparison, the ARCEP observatory is the reference rather than commercial press releases. See our guide to French telecom operators for more.

Check your coverage

Is your phone 5G-compatible in France?

To use 5G in France, your phone needs to support the bands operators actually use here: n28 (700 MHz), n1 (2.1 GHz) and above all n78 (3.5 GHz). Most smartphones sold in Europe since 2021 support these bands.

  • Apple: iPhone 12 and later (European models, without mmWave).
  • Samsung: Galaxy S20 and later, Galaxy A 5G (A32 5G, A52 5G, A54, A55, A56), Galaxy Z Fold/Flip.
  • Google Pixel: Pixel 5 and later.
  • Xiaomi, OPPO, OnePlus, Motorola: most mid-range and high-end devices since 2022.

A 4G SIM normally works on 5G without replacement, provided your plan includes 5G. To check: Settings then Mobile Network then Preferred Network Type. If 5G is not listed, your phone is 4G-only.

If your phone is not 5G-capable, nothing changes. 4G covers more than 99% of the French population per ARCEP and will remain active for years.

Fixed 5G boxes for home internet

If fibre has not reached your area, a fixed 5G box can be a practical alternative. Several French operators sell dedicated 5G modems/routers that connect to the mobile network instead of a wired line.

Typical speeds range from 100 to 500 Mbps depending on the local 5G signal and network load. Latency is higher than fibre, and performance varies more.

When a 5G box makes sense

  • Your address has no fibre and ADSL speeds are poor (under 10 Mbps).
  • Strong 5G coverage exists at your location.
  • You need a connection quickly without waiting for fibre installation.

When fibre is better

  • Fibre is available (more than 94% of eligible French premises by end of 2025, per ARCEP).
  • You need consistently low latency for gaming or work VPNs.
  • Multiple people stream video simultaneously.

More detail in our internet box guide and fibre optic guide.

5G and health: what ANSES, ANFR and WHO actually say

Health questions about 5G have been reviewed by ANSES, the French national agency for health and safety. In its expert review on exposure to the frequencies used by 5G (published April 2021, with follow-up notes), ANSES concluded that, based on current scientific knowledge:

  • for the 700 MHz and 3.5 GHz bands, no proven health effect has been demonstrated at regulatory exposure levels;
  • for the 26 GHz band, available data are insufficient and further research is recommended;
  • continued monitoring of real-world exposure and an updated state-of-the-science review are needed.

France's regulatory framework is set by Decree 2002-775, which fixes public exposure limits: 36 V/m at 700 MHz, 41 V/m at 900 MHz, 58 V/m at 1,800 MHz and 61 V/m above 2 GHz (including 3.5 GHz). These limits align with the international ICNIRP recommendations recognised by the World Health Organisation.

ANFR enforces these thresholds on the ground. Every measurement is published on cartoradio.fr: you can search by address and see the sites and measurements near you. This page reports those official positions and does not make any health claim beyond them.

Plans that include 5G in France

This page does not rank commercial plans. For an overview of how 5G is included in each operator's offers (default, paid option, low-cost brands), see our guide to French mobile plans.

As a rule, in 2026 5G is increasingly included at no extra cost in data-rich plans from the main operators (Orange, SFR, Bouygues Telecom, Free) and their digital brands (Sosh, RED, B&You). Some entry-level plans remain 4G-only: check the plan's product sheet to confirm.

5G in France: advantages and considerations

What 5G brings

  • 3 to 10x faster than 4G on 3.5 GHz (200–800 Mbps typical)
  • Lower latency for gaming, video calls, cloud apps
  • Better performance in crowded areas
  • Fixed 5G box as a home internet alternative without fibre
  • Often included at no extra cost in current plans

Things to consider

  • Geographic coverage is uneven outside major cities
  • Needs a phone supporting n28 / n1 / n78 bands
  • Slight extra battery drain compared with 4G
  • 5G icon may be DSS: not always a gigabit experience
  • 4G+ remains sufficient for most everyday use

Frequently asked questions about 5G in France

How much of France is covered by 5G in 2026?
According to ARCEP's mobile observatory, more than 80% of the French population is covered by at least one 5G operator in early 2026. ANFR (the national frequency agency) counts more than 54,000 authorised 5G sites, of which roughly 47,000 are operational, mainly on the 700 MHz, 2.1 GHz and 3.5 GHz bands. Geographic coverage of the territory is lower than population coverage: rural areas and some valleys remain less well served. Check 5G at your address on the official map: monreseaumobile.arcep.fr.
What is the difference between 'true 5G' (3.5 GHz) and 5G DSS?
5G in the 3.5 GHz band uses dedicated spectrum that ARCEP auctioned in November 2020. Typical real-world speeds are 200 to 800 Mbps with reduced latency. 5G DSS (Dynamic Spectrum Sharing) reuses existing 4G bands (700 MHz, 2.1 GHz) by dynamically sharing capacity between 4G and 5G. Speeds in DSS are close to good 4G+: usually 100 to 300 Mbps. Your phone will show '5G' in both cases, but the performance difference is real.
Which frequency bands does France use for 5G?
ARCEP has allocated four main bands for 5G in France: 700 MHz (wide-area coverage and indoor reception), 2.1 GHz (capacity layer, often via DSS), 3.5 GHz (the core 5G band, 310 MHz auctioned to four operators in November 2020), and 26 GHz (mmWave, allocated through ARCEP calls for tenders). The 26 GHz band is mostly used for industrial sites and pilots in 2026. An extension in the 3,410-3,490 MHz segment becomes available across mainland France from 25 July 2026.
Is 5G safe? What does ANSES say?
In its expert review on exposure to the frequencies used by 5G (published April 2021, with follow-up notes), ANSES concluded that, based on current scientific knowledge, no proven health effect has been demonstrated at regulatory exposure levels in the 700 MHz to 3.5 GHz bands. For the 26 GHz band, ANSES said data are insufficient and recommends further research. ANFR monitors compliance with regulatory thresholds set by Decree 2002-775 (36 to 61 V/m depending on frequency) and publishes its on-site measurements on cartoradio.fr. France's limits align with international ICNIRP recommendations recognised by the WHO.
How do I check 5G coverage at my address?
Three official sources complement each other. ARCEP's coverage map (monreseaumobile.arcep.fr) shows declared coverage of all four operators in 2G, 3G, 4G and 5G for every address. Cartoradio (cartoradio.fr), run by ANFR, lists every authorised transmitter site and its exposure measurements. Each operator also offers its own 5G eligibility tool. These three maps may slightly diverge: the ARCEP map is the reference when comparing operators on the same basis.
Is my phone compatible with 5G in France?
Most smartphones sold in Europe since 2021 support the bands France uses: n28 for 700 MHz, n1 for 2.1 GHz and especially n78 for 3.5 GHz. On Apple, this means iPhone 12 and later (European models, without mmWave). On Samsung, Galaxy S20 and later, plus the Galaxy A 5G line (A32 5G, A52 5G, A54, A55, A56). Check Settings then Mobile Network then Preferred Network Type, or search 'n78' in the spec sheet. A 4G SIM normally works on 5G without replacement.
Which 5G use cases actually matter in 2026?
Four families of use cases benefit clearly from 5G. First, very high-definition video streaming and cloud gaming, thanks to high downlink speeds and reduced latency. Second, mobile hotspot or a fixed 5G box when fibre is not available. Third, dense locations (stations, stadiums, exhibitions) where 4G saturates. Fourth, industrial IoT and private 5G networks for Industry 4.0: logistics, predictive maintenance, automated ports. For everyday web, messaging and social media, 4G+ is still more than enough.
Can a fixed 5G box replace fibre at home?
A fixed 5G box is a sensible option where fibre is not eligible and ADSL is poor. Typical speeds range from 100 to 500 Mbps, with higher latency than fibre and signal quality depending on the local 5G antenna. According to ARCEP's fixed broadband observatory, fibre passed more than 94% of eligible premises in France by end of 2025: if fibre is available at your address, it remains more stable. Otherwise, a 5G box is a workable interim solution while fibre rolls out.
