Choosing the right M2M SIM for your fleet of industrial IoT devices is a critical decision: network coverage, pay-as-you-go rates, SLAs, international roaming, APN security, LTE-M/NB-IoT compatibility, and—an often-overlooked factor—the planned phase-out of 2G and 3G, which will render thousands of already-deployed modems obsolete. This 2026 comparison, based on the most recent ARCEP data, analyzes the offerings of major French carriers, specialized MVNOs (1NCE, Tele2 IoT), and multi-carrier SIMs, to help you make a choice that will stand the test of time over the next 10 years.

In a Nutshell: What to Take Away from This Comparison​

Before getting into the details, here are the key takeaways for decision-makers who are pressed for time:

  • Coverage: The four carriers (Orange, SFR, Bouygues, Free) now cover 99% of the population with 4G thanks to the 2018 New Deal Mobile. The difference lies in rural areas and the size of the territory, where Orange maintains a slight lead.
  • Pricing: Bouygues and SFR are generally the most aggressive on volume plans; Orange charges a coverage premium.
  • Resilience: No single-carrier SIM card covers 100% of a multi-site network. The multi-carrier SIM (multi-IMSI / eUICC) automatically switches to the best network and eliminates single-carrier dead zones.
  • 2026–2028 Deadline: 2G will be shut down (Orange will shut down its network between September 22 and October 20, 2026), and 3G will follow around 2028. Any new deployment must be LTE-M / NB-IoT / 4G at a minimum, or it will quickly become obsolete.
  • Security: For critical infrastructure (NIS2), a private APN + VPN is no longer an option but a prerequisite.

What is an M2M SIM card, and how does it differ from a consumer SIM card?​

An M2M SIM (Machine-to-Machine), now more commonly referred to as an IoT SIM, is a SIM card designed specifically for industrial and connected devices. It differs from a smartphone SIM in almost every way:

FeatureConsumer SIMM2M IoT SIM
Operating Temperature0 °C to +40 °C−40 °C to +85 °C
Lifespan2–3 years10–15 years
FormatNano SIM (4FF)Industrial 2FF/3FF solderable (MFF2), eSIM
ResistanceStandardVibration, humidity, corrosion
Data allowanceUnlimited (shared)Low (1 MB–5 GB/month)
RoamingEU “Roam Like Home”Dedicated M2M contracts (≠ RLH)
Private APNNoAvailable
Static IPNoOptional
MonitoringNoDashboard / Fleet API
eUICC (remote profile)NoAvailable
CancellationMonthly12–36-month contracts

Industrial SIM format: IoT gateways and routers most often include a SIM slot in the 2FF (mini-SIM, 25×15 mm) or 3FF (micro-SIM), or even a soldered eSIM (MFF2) for high-vibration environments. This must be verified before placing any order—an incorrect format will halt the entire deployment.

Key Takeaway: An M2M SIM card isn't just a "cheap plan." It's an industrial component designed to last as long as the machine it's installed in.

Mobile Coverage in France in 2026: What the ARCEP Data Shows​

Coverage is the most important factor when choosing an M2M SIM card. Here is the actual state of the network, based on ARCEP data from Q4 2025 (published in March 2026), rather than on the operators’ marketing claims.

4G: Everyone Covers More Than 99% of the Population​

Thanks to the mandatory requirements of the 2018 New Deal Mobile, the four carriers now cover more than 99% of the French population with 4G. The battle is therefore no longer about population coverage, but rather about:

  • Area coverage (rural areas, mountainous regions, secondary roads), where Orange maintains a lead.
  • Indoor coverage / signal quality, now rated by ARCEP on a three-tier scale: very good, good, limited.
  • Remaining dead zones, addressed by the targeted coverage program (several thousand shared cell towers).

Resource Sharing: The SFR/Bouygues “Crozon” Agreement​

An important factor for network resilience: SFR and Bouygues Telecom share part of their network in less densely populated areas (a network-sharing agreement known as the “Crozon” agreement). In practice, in these areas, choosing SFR or Bouygues may amount to connecting to the same physical antenna—which reduces the value of a failover between these two providers and increases the value of a failover that includes Orange (an independent network). Free, for its part, benefits from roaming on the Orange network in areas it does not yet cover.

Key Frequency Bands for the IoT​

BandFrequencyIoT Use
B28700 MHzLong range, indoor penetration, rural
B20800 MHzRural coverage, basements
B8900 MHzExtended coverage
B31800 MHzUrban capacity, data rate
B1/B72100/2600 MHzHigh urban density
n783.5 GHz (5G)Very high data rates, dense areas

For a sensor located underground or in a rural area, it’s the low bands (700/800 MHz) that matter—not the urban 5G highlighted in advertisements.

⚠️ End of 2G and 3G: The Deadline That Makes Networks Obsolete​

This is the most underestimated aspect of an IoT deployment in 2026, and it deserves its own section.

  • 2G: Orange will shut down its 2G network between September 22 and October 20, 2026. Other carriers are following a similar schedule. ARCEP even plans to eliminate the requirement to map 2G coverage, a sign that the technology is reaching the end of its life cycle.
  • 3G: scheduled shutdown around 2028.

Direct consequence: Any 2G-only modem or IoT module (still very common in older meters and alarms) will stop working as of fall 2026. A 2G/3G module without 4G fallback will stop working around 2028.

What should I do?

  • For any new deployment: require 4G (LTE Cat-1 / Cat-1 bis) or low-power IoT LTE-M / NB-IoT modules, which will continue to be supported well beyond 2030.
  • For existing 2G/3G infrastructure: plan for hardware replacement before the deadline. An LTE-M/NB-IoT-compatible SIM card is not sufficient if the modem is not compatible.
  • Prioritize SIM cards for which the carrier explicitly guarantees long-term support for LTE-M and NB-IoT.

Eziwan Tip: Eziwan gateways and SIM cards support 4G/LTE-M with fallback, designed to withstand these outages without requiring on-site intervention.

M2M Operators in France: An Overview for 2026​

Orange Business (M2M Data / Orange IoT)​

Orange is the incumbent carrier with the most extensive coverage, particularly in rural areas and overseas territories.

M2M Plans:

  • Flux M2M Lite: data only, plans ranging from 1 MB to 2 GB/month
  • Flux M2M Pro: data + SMS + voice, private APN available
  • Orange IoT Suite: SIM fleet management + connectivity + API

Key Strengths:

  • Most extensive 4G coverage, with a lead in rural and outlying areas
  • Nationwide LTE-M network deployed for low-power IoT
  • DOM/COM coverage (Réunion, Martinique, Guadeloupe, the Antilles, etc.)
  • Enterprise SLA with up to 99.9% availability
  • GSMA member for industrial eSIM profiles
  • Independent network (not shared): suitable as a “second carrier” in a failover scenario

Weaknesses:

  • Premium rates: often 20–40% higher than SFR and Bouygues
  • M2M contracts typically last 24–36 months
  • Minimum order quantities can be high (≈100 SIM cards)

Estimated rates (data only, excluding add-ons):

Data Allowance / MonthEstimated Price / SIM / Month
1–5 MB2–4 €
50–100 MB4–8 €
500 MB – 1 GB8–15 €

SFR Business (SFR IoT)​

SFR offers competitive M2M plans, providing good value for money on large-scale deployments and a popular pooling system.

M2M Plans:

  • SFR IoT Connect: M2M data connectivity
  • SFR IoT Platform: fleet management + APIs + alerts
  • Pooled Plans: a shared total data allowance across all SIM cards under the contract

Key strengths:

  • Competitive rates (often 15% to 25% lower than Orange for average volumes)
  • Pooling: ideal when usage varies from one SIM to another
  • 4G network comparable to Orange’s, with high-performance 5G in urban areas
  • Well-documented fleet management API

Weaknesses:

  • Coverage slightly behind Orange in very rural areas
  • Network shared with Bouygues (“Crozon”) in sparsely populated areas: SFR↔Bouygues failover is not very effective in these areas
  • M2M support is sometimes less responsive than in the Enterprise segment

Estimated rates:

Data Allowance / MonthEstimated Price / SIM / Month
10 MB€1.50–3
100 MB€3–6
1 GB€6–12

Bouygues Telecom for Business (IoT)​

Bouygues has significantly improved its coverage and often offers the lowest rates on the market for large data plans.

M2M Offerings:

  • Bouygues Telecom IoT: Data SIM, SMS, voice
  • FleetMap: SIM fleet management tool
  • Partnerships with integrators for major IoT platforms

Strengths:

  • Very competitive prices, often the lowest for large volumes
  • Full 4G coverage, “Crozon” network sharing with SFR in sparsely populated areas
  • Volume-based pricing starting at ~50 SIM cards
  • Good level of service for small and medium-sized businesses

Weaknesses:

  • More limited presence in the French overseas departments and communities
  • Network shared with SFR in sparsely populated areas (same concern regarding failover)

Estimated rates:

Data Allowance / MonthEstimated Price / SIM / Month
10 MB€1.20–2.50
100 MB€2.50–5
1 GB€5–10

Objenious / LoRaWAN (Bouygues)​

For low-power, low-data-rate applications (remote water/gas meter reading, asset tracking, environmental sensors), LoRaWAN is an alternative to cellular networks:

  • National LoRaWAN network covering most of the population
  • Extremely low power consumption: several years on a single battery
  • Limitation: not suitable for video, high data rates, or frequent OTA updates

Note: The LoRaWAN ecosystem is evolving (acquisitions, strategic repositioning of players). Verify the long-term viability of the network and the commercial offering before making a long-term commitment.

MVNOs and Specialized IoT Operators​

1NCE — the “lifetime” SIM card with a one-time fee​

1NCE offers a radical model: a one-time payment of about $10/$12 for 500 MB of data + 250 text messages valid for 10 years, on the Deutsche Telekom network and its partners (including Orange in France), with coverage in 170+ countries. The SIM supports 2G, 3G, 4G/LTE-M, NB-IoT, and is advertised as “5G-ready.”

For:

  • Very low-power deployments (sensors, remote meter reading, asset tracking)
  • Virtually zero OPEX after purchase; predictable costs over 10 years
  • OpenVPN tunnel included, along with a management portal and API
  • Industrial (ruggedized) and eSIM/eUICC versions available (for a small additional fee)

Cons:

  • 500 MB lifetime limit: insufficient for video or frequent OTA updates (top-up: ~€12 for 500 MB)
  • Limited data speed (up to 1 Mbit/s)
  • No dedicated private APN, unlike with enterprise carriers
  • Support is primarily text-based, except for the premium plan

1NCE is excellent for simple, straightforward applications. For industrial monitoring, regular VPN remote access, or video, you'll need a single-carrier or multi-carrier solution.

Tele2 IoT / Telenor Connexion​

European operators specializing in IoT, with attractive multi-country offerings for international deployments and mature fleet management.

Arkessa / ZARIOT / Transatel / Onomondo​

eUICC / multi-IMSI solutions that allow switching between carriers based on coverage, with a unified core network—ideal for deployments across multiple countries and for avoiding vendor lock-in.

Multi-carrier SIMs: The Solution for Critical Industries​

A multi-carrier SIM (multi-IMSI / eUICC) is a card capable of automatically connecting to the carrier with the best signal at each location and switching back in the event of a network outage.

How It Works​

Typical bands: Orange B20 (800 MHz) in rural areas, SFR B3 (1800 MHz) in urban areas, and Bouygues B28 (700 MHz) as a supplement. Selection is based on the RSRP/RSRQ measured on-site.

Benefits of a Multi-Carrier SIM Card​

CriterionSingle-carrier SIMMulti-carrier SIM

CostLowSlightly higher (+10–20%)
Management1 contract1 multi-operator contract
EU RoamingVariable / optionalOften included
“Blind” deploymentRisky (coverage must be verified site by site)Secure (the best network is selected on-site)

Ideal use cases: pumping stations, wind and solar farms, agricultural sites, multi-site remote meter reading, moving vehicles, multi-country deployments, and any site where checking carrier coverage on a carrier-by-carrier basis before installation would be too costly.

“Crozon” Reminder: For true redundancy, the failover must include Orange (an independent network) and not just SFR and Bouygues, which share their network in sparsely populated areas.

The Eziwan SIM Card​

The Eziwan SIM is a multi-carrier M2M SIM included in our plans:

  • Automatic switching between Orange / SFR / Bouygues based on the best coverage
  • Secure private APN (encrypted traffic between the gateway and the Eziwan cloud, data center in France)
  • Monitoring dashboard: RSRP, RSRQ, data usage in real time
  • Unified billing: a single contract for the entire fleet
  • No minimum volume commitment: order from 1 to 1,000 SIM cards
  • LTE-M and 4G compatible: designed to transition through the phase-out of 2G/3G without disruption

Private APN: Why It's Essential in Industry​

The private APN (Access Point Name) creates a dedicated virtual network between your SIM cards and your cloud infrastructure, without going through the public internet.

Traffic never passes through the public internet: a dedicated tunnel between the SIM and the data center; a static IP address is available per SIM.

Advantages of a private VPN:

  • Traffic is never exposed to the public Internet (reduced attack surface)
  • Fixed IP addressing possible (same IP per SIM, simplifies remote access)
  • Complete network isolation from the operator’s other customers
  • A key component for NIS2 compliance for critical and important entities

Public APN vs. Private APN:

Public APNPrivate APN
Internet exposureYesNo (dedicated tunnel)
Fixed IPRarePossible
Client IsolationNoYes
NIS2 ComplianceInsufficient on its ownRecommended
Additional Cost—~+1–3 €/SIM/month

Availability: Orange, SFR, and Bouygues all offer private APNs; the Eziwan SIM includes one by default.

Typical Data Usage by Use Case​

Choosing a plan that’s just the right size helps you avoid overpaying (or running out of data). Observed ranges:

Use CaseVariablesPollingMonthly Usage
Remote meter reading3–515 min1–5 MB
Pumping station (M340 PLC)10–2030 s10–50 MB
Energy monitoring20–5010 s50–200 MB
Multi-device SCADA100–5001 s200–500 MB
720p video surveillance—Continuous3–10 GB
VPN remote access (idle)——5–20 MB (keepalive)
VPN remote access (30-min session)——50–500 MB depending on activity

Optimization through edge computing: A gateway that filters data locally (dead band, aggregation, compression) before transmission reduces 4G data usage by 70 to 95%. An M340 site with 30 variables can go from ~150 MB/month to 15–25 MB/month — which, across 500 sites, means switching from a “200 MB” plan to a “50 MB” plan and achieving substantial savings across the entire fleet.

International Roaming: Things to Watch Out For​

For equipment deployed outside of France:

European Union: Please note that M2M plans do not automatically qualify for the “Roam Like Home” benefit, which is reserved for consumer plans. M2M roaming is subject to specific contractual terms: always check your carrier’s M2M terms and conditions (data allowances, permitted duration of permanent roaming, and restrictions on “permanent roaming”).

Outside the EU: Charges per MB can be very high (in the range of +0.5 to 2 €/MB). For international deployment, opt for a local SIM or a global multi-IMSI SIM (Eziwan, Tele2 IoT, Onomondo) that negotiates network access on a country-by-country basis.

Permanent roaming: Some countries (and some host operators) restrict or prohibit permanent roaming for fixed devices. A sustainable deployment abroad must rely on a multi-IMSI plan or a local SIM card, not on “tolerated” roaming.

How to Choose: A Quick Decision Tree​

  • Simple sensors, very low power consumption, fixed budget over 10 years → 1NCE or an operator’s LTE-M offering.
  • Multi-site national park, rural areas, high criticality → Multi-carrier SIM (Eziwan) with private APN.
  • Large urban volumes, cost optimization → Bouygues or SFR (pooling).
  • Overseas territories, maximum coverage required → Orange.
  • International/multi-country deployment → Global multi-IMSI SIM (Eziwan, Tele2 IoT, Onomondo).
  • Video / frequent remote access → Generous data plan from a single operator or multi-operator provider; definitely not a capped “lifetime” SIM.

In any case: at least 4G/LTE-M modules (never 2G/3G alone) and a private APN whenever the data is sensitive.

FAQ — Industrial IoT M2M SIM​

Can I use a consumer SIM card in an IoT gateway? Technically, yes, but it’s not recommended. Consumer SIM cards support a limited temperature range (0–40 °C), have a shorter lifespan, and do not offer a private APN, fleet monitoring, or an industrial SLA. For a fleet deployed in the field, the additional cost of an M2M SIM is more than offset by the reliability and centralized management it provides.

Will my 2G or 3G devices continue to work? No, eventually. Orange is shutting down its 2G network between September 22 and October 20, 2026; other carriers will follow suit, and 3G will be phased out around 2028. Any 2G-only module will be out of service as of fall 2026; a 2G/3G module without 4G fallback will be out of service around 2028. For any new project, insist on 4G / LTE-M / NB-IoT hardware.

What is the minimum data usage of an M2M SIM in standby mode? Without business traffic, an M2M SIM only consumes data for network maintenance signals (keep-alive, heartbeat): depending on the carrier and configuration, 1–10 MB/month. With a private APN and a VPN tunnel (OpenVPN/IPSec) maintained continuously, expect 5–15 MB/month in keep-alive traffic, excluding application data.

Can you switch carriers without having to reconfigure everything? With an eUICC (eSIM), yes: the carrier profile is reconfigured remotely, without any on-site intervention. With a standard physical single-carrier SIM, you have to physically replace the card. Eziwan’s multi-carrier SIM eliminates this problem: a single SIM automatically manages all three French networks.

What is the difference between LTE-M and NB-IoT? LTE-M offers higher data rates, low latency, and supports mobility (moving objects, voice capable)—making it suitable for asset tracking and real-time telemetry. NB-IoT is designed for very low-power, stationary devices (such as underground meters), offering excellent signal penetration but lower data rates and higher latency. Both technologies will survive the phase-out of 2G/3G.

Do M2M SIM cards comply with French regulations? Yes. M2M plans offered by French carriers are regulated by ARCEP. IoT data SIM cards do not require end-user identification (no ID required), except for plans that include voice calls or outgoing text messages to consumer numbers.

How do you manage 500 SIM cards spread across 500 locations? Through a fleet management portal: real-time data usage per SIM, detection of inactive or over-consuming SIMs, remote activation/deactivation, signal monitoring (RSRP/RSRQ), and threshold alerts. The Eziwan portal integrates this management into the same dashboard as your equipment monitoring, eliminating the need to switch between multiple interfaces.

Is a multi-carrier SIM much more expensive? Generally 10% to 20% more than an equivalent single-carrier SIM. For a critical site, this additional cost is negligible compared to the cost of an outage or a technical visit caused by a coverage gap that wasn’t properly anticipated.
