Understanding the 2025 Migration to 4G OBUs and EETS Accreditation: A Guide for Fleets

Introduction to the 2025 Tolling Migration

By late 2025, the European truck-toll landscape is shifting in two ways at once: mobile networks are sunsetting legacy 2G/3G connectivity, and more countries are aligning with the European Electronic Toll Service (EETS) to make cross-border billing simpler. For dispatchers and fleet owners, Understanding the 2025 Migration to 4G OBUs and EETS Accreditation: A Guide for Fleets means fewer devices on the windshield, clearer compliance paths, and better data—if you pick the right hardware and provider.

What’s new, concretely?

4G-capable OBUs (often LTE/LTE-M with GNSS) are replacing older 2G/3G devices as networks phase out, a trend toll service providers flag explicitly in their 2025 updates.
New or expanded EETS domains arrive, notably the Czech Republic’s “CZmyt” toll domain (EETS-enabled) and Switzerland’s LSVA III framework, which formalizes EETS and NETS (the new national service) as standard ways to pay the heavy vehicle charge.
The European Commission continues to sharpen the definitions of EETS providers vs. toll chargers, pushing interoperability across member states.

The payoff for fleets is tangible: a single, modern OBU with over-the-air updates and API tolling integration can cover more networks and deliver cleaner, near-real-time spend and compliance data across borders.

Overview of 4G On-Board Units (OBUs)

A “4G OBU” combines three functions most fleets want in one box:

GNSS-based tolling: satellite positioning (GPS/Galileo) provides distance/zone detection for GNSS toll domains.
4G/LTE (often LTE-M) backhaul: reliable, secure data links for transaction exchange, remote diagnostics, and OTA updates (critical as 2G/3G sunsets accelerate).
Interoperability software: an EETS-ready stack that lets your provider activate new European tolling systems remotely, including newly accredited toll domains like CZmyt. Providers now market “classic EETS OBU” and “advanced 4G OBU” side by side, with shared software and OTA capabilities.

Why 4G now? Besides coverage and throughput, LTE/LTE-M brings better security primitives (TLS, modern cipher suites), more stable session handling, and room for tolling technology advancements such as predictive anomaly checks and fraud detection mechanisms on the device. Several major service providers are explicitly steering customers away from legacy modems, citing the 2G/3G phase-out across Europe in 2025–2026.

Significance of EETS Accreditation

EETS accreditation is your passport to unified, multi-country tolling with one contract and one OBU. The Commission’s framework defines the roles: toll chargers operate networks; EETS providers supply equipment and settle tolls across domains. As more networks are added and accredited, fleets can switch on new coverage with a click instead of swapping boxes at the border.

A few practical benefits:

Tolling interoperability across many countries with multi-country tolling on one invoice.
Fewer devices to install, fewer cables to break, and one set of toll compliance procedures across borders.
Real-time toll data feeds consolidated reporting, improving fleet cost management and tolling efficiency at month-end.
Providers now highlight 4G OBU lines and roadmaps—look for explicit, named support for Czech and Swiss domains in 2025.

New Tolling Schemes in 2025

The CZmyt Toll Domain in the Czech Republic

Czech tolling moved to GNSS in 2019 under CzechToll/SkyToll, but 2025 brings a branding and EETS-enablement update: “CZmyt” becomes the official EETS toll domain, with providers announcing go-live availability in September 2025. This is a clean signal that EETS is real for the Czech network and that fleets can enroll via their cross-border OBU rather than a local box.

From the Czech side, the official portal continues to publish domain and network updates (e.g., new tolled segments in 2025 and portal/domain changes). If you’re already registered, mind those operational updates; if you’re switching to EETS, coordinate the handoff and deposit/refund logistics for any legacy devices with your provider.

Why it matters for routes

The Czech Republic sits on key east-west and north-south lanes. Being able to activate CZmyt on the same EETS OBU that covers Germany, Austria, and Poland reduces swaps and re-installs and simplifies tolling system integration with your TMS. Early commercial pages from providers and fuel networks flagged 2025 Czech EETS availability—worth a quick confirmation call if you run CZ regularly.

Switzerland’s Transition to EETS

Switzerland is not in the EU, but its LSVA (performance-related heavy vehicle charge) is undergoing a major upgrade: LSVA III must be in place by the end of 2025, with the new digital options fully mainstreamed thereafter. The Federal Office for Customs and Border Security (FOCBS) confirms that foreign vehicles can pay the charge through EETS, NETS (the new national service), or a manual online workflow (NMTS). FOCBS also lists approved EETS providers for Switzerland (e.g., Telepass, Toll4Europe, Axxès, Eurowag).

Key Swiss steps and players:

LSVA III program completion scheduled by end-2025 (system replacement).
NATRAS AG selected as the National NETS Provider for the new regime, providing basic LSVA services for Swiss-registered vehicles; private EETS providers operate alongside.
Trade press and providers highlight that EETS in Switzerland is ramping during 2025, with some comms referencing a cut-over period into 2026—so fleets should plan device provisioning and account migrations accordingly.

Bottom line: Switzerland’s EETS transition opens a clean cross-border path for foreign fleets. If your OBU and provider are approved for LSVA III, you can handle cross-border tolling with the same box you use in the EU—no more separate Swiss black-box hurdles.

Choosing the Right Tolling Solution for Your Fleet

Evaluating 4G OBU Options

When you compare tolling devices, focus on the items that actually move the needle in 2025:

Evaluation dimension	What to look for (2025 reality)	Why fleets care
Radio & GNSS	4G/LTE (ideally LTE-M for low power), GNSS (GPS/Galileo), DSRC where required	Survives 2G/3G sunset; stable in dense urban/rural coverage.
Coverage roadmap	Named support for CZmyt and Switzerland (LSVA III via EETS); ability to add domains OTA	Avoid device swaps; push new domains remotely as they accredit.
EETS status	Provider is an EETS provider with active accreditations and an announced LSVA III track	True tolling interoperability and faster onboarding.
Over-the-air updates	Firmware and domain activation without workshop visits	Cuts downtime and technician calls.
APIs & data	Real-time transactions, cross-border billing, webhooks; TMS/telematics connectors	Cleaner fleet management and tolling cost optimization.
Security & privacy	TLS, signed firmware, privacy policy aligned to GDPR; privacy compliance measures for GNSS data	Reduces risk; simplifies audits.
Diagnostics	Remote heartbeat, remote diagnostics, tamper alerts	Less manual troubleshooting, faster SLA.
Support/SLA	Clear cut-over plans for CZ & CH, multi-language 24×7 support	Fewer late-night calls from drivers stuck at a border.

Tip: Ask the provider to name their 4G OBU model family and share a one-pager on supported toll domains today and planned by quarter. Many providers now market a distinct “4G OBU” line, and you want that explicitly on your order.

Benefits of EETS Accreditation

With EETS accreditation in your corner, you get:

One contract, one box, many countries: fewer installs and less windshield clutter.
Faster domain expansion: e.g., activation of CZmyt or newly accrediting toll chargers without hardware swaps.
Consolidated analytics: unified reports for tolling system evaluation, tolling system comparison, and tolling efficiency KPIs.
Better uptime: modern EETS devices tend to be the first to get tolling system updates and over-the-air fixes.

Practical Country Notes (2025)

Czech Republic (CZmyt)

Go-live: EETS providers announced CZmyt availability in September 2025.
What to do: If you run CZ, confirm your EETS OBU is enabled for CZmyt, then decide whether to retire any local MYTO CZ device and reclaim deposits.
Why it’s smoother: Czech toll road network changes continue (new segments in H2 2025), so an EETS path reduces admin when the network expands.

Switzerland (LSVA III + EETS/NETS/NMTS)

System renewal: LSVA infrastructure replacement by end-2025; Swiss comms highlight 2025 transition steps and full LSVA III adoption into 2026.
Payment options: EETS, NETS (via NATRAS for Swiss-registered fleets), or manual portal (NMTS) for occasional trips. FOCBS lists accredited EETS providers for Switzerland.
Action item: Ensure your EETS box and account are whitelisted for Switzerland before the old LSVA processes retire.

“How-To” for Fleet Selection and Rollout

1) Map your lanes and deadlines

Highlight CZ corridors and CH crossings where the new rules bite first.
Note internal cut-off dates for OBU upgrades and driver pack changes.

2) Choose the provider by 4 factors

Coverage (today + Q-by-Q roadmap including CZmyt and Switzerland EETS transition).
Device (explicit 4G OBU; OTA domain activation; hybrid tolling models support for GNSS + DSRC).
Operations (API for billing & cross-border billing, real-time toll data, dispute process, maintenance cycles, and calibration procedures if required by domain).
Security & compliance (firmware signing, GDPR stance on GNSS data, privacy compliance measures, data security standards).

3) Pilot first, then scale

Run a 4–8 week pilot on your heaviest CH/CZ lanes. Measure:

Transaction success rate, tolling cost optimization (rebates/discounts), and toll compliance flags.
Driver experience (user experience improvements): simpler logins, fewer device prompts.
Remote diagnostics: how quickly support clears faults.

4) Integrate to your stack

Connect the provider’s API tolling integration to your TMS/BI, stream tolling devices status, and automate cross-border tolling checks.
Use fleet telematics integration to co-display geofenced toll zones, HGV restrictions, and dynamic toll pricing experiments as they emerge.

5) Train drivers

Short QR card: how to confirm domain LEDs, what to do after border crossings, how to spot “fallback” or error states.
Tolling compliance strategies: receipts, dispute flows, and what to do if the OBU was unplugged at a checkpoint.

Side-by-Side: Swiss Payment Paths (2025–2026)

Path	Who uses it	Hardware	Enrollment	Pros	Watch-outs
EETS	Foreign carriers; also attractive to multi-country fleets	EETS OBU (4G)	Contract with an FOCBS-approved EETS provider	One box, many countries; over-the-air updates; unified billing	Ensure LSVA III accreditation status and domain activation dates.
NETS	Swiss-registered fleets needing the national option	National NETS OBU/services via NATRAS	Swiss process with FOCBS/NATRAS	Designed for domestic basics; integrated with CH law	Less cross-border flexibility than EETS.
NMTS (manual)	Occasional trips	No OBU; online pre-registration and payment	Web portal, card or cash at designated border offices	No device needed for infrequent entries	More admin; must pre-pay correctly; not for frequent crossers.

Risk & Governance: Don’t Skip These

Device tamper & loss: insist on OBUs with tamper alarms and strong identity binding; verify procedures for lost/stolen units to avoid fraudulent use.
Fraud detection mechanisms: ask how your provider flags location anomalies (e.g., teleporting between domains) and handles toll regulations disputes.
Privacy: GNSS logs are personal data under GDPR when linked to a driver—document privacy compliance measures and retention periods in your DPA.
Resilience: check redundancy (fallback APNs, roaming profiles) so a local carrier outage doesn’t halt toll reporting.
Regulatory alignment: monitor toll policy updates via your provider’s newsletters and the EETS Facilitation Platform progress reports for new domains and accreditation timetables.

Quick FAQs (2025)

Q: Do I need a 4G OBU this year?

If you cross borders or plan to activate CZmyt or Switzerland’s LSVA III via EETS, yes—migrate now. Providers and fuel-card networks are explicit: the 2G/3G sunset is here, and 4G/LTE devices are the supported path forward.

Q: Will one EETS box cover all of Europe instantly?

No; each toll domain requires provider accreditation plus technical and commercial activation. But 2025 adds important pieces—CZmyt and CH’s LSVA via EETS—reducing the remaining gaps.

Q: We rarely enter Switzerland. Can we avoid devices?

Yes—use the NMTS manual online process, but it’s extra admin and riskier for repeat traffic. EETS accreditation plus a 4G OBU is the better long-term answer for even moderate CH volume.

Q: Which providers are recognized in Switzerland?

FOCBS lists Telepass, Toll4Europe, Axxès, Eurowag as approved EETS providers (with more in the pipeline). Check the live list before you order.

Field Checklist: Make the Migration Boring (In the Best Way)

Inventory every unit and lane that touches CZ or CH; tag 2G/3G OBUs for swap.
Contract a named EETS provider with 4G OBU and share your lane map; demand a domain activation timeline (CZmyt, Switzerland).
Pilot 10–20 vehicles; compare billed vs. expected charges; verify toll data interoperability into your BI.
Train drivers on LED states, border behaviors, and fallback to NMTS (CH) if the plan fails.
Cut over by corridor; reclaim deposits on retired boxes; archive the old device IDs in your asset register.
Audit privacy and data retention; document security protocol guides for device loss, theft, and tampering.
Review invoices monthly for anomalies; use your provider’s dispute channel and attach GPS traces where allowed.

Conclusion

The combination of 4G OBUs and EETS accreditation is finally delivering the practical version of “one box, many borders”—and 2025 is the year it clicks for two pivotal networks: CZmyt in the Czech Republic and LSVA III in Switzerland. If you run these corridors, upgrade now: deploy a 4G-capable, EETS-ready device; integrate its real-time toll data and APIs into your TMS; and lock down privacy compliance measures and security procedures as part of the rollout. With those steps, Understanding the 2025 Migration to 4G OBUs and EETS Accreditation: A Guide for Fleets goes from buzzword to boring—and boring, in fleet operations, is a beautiful thing.
