This week, TOMIA and SEGRON announced a strategic partnership that tackles one of roaming’s longest-running problems: the gap between what operators think is happening on roaming networks and what users actually experience.

For an industry built on SLAs, steering rules, KPIs, and dashboards, that gap has always been uncomfortable. Sometimes invisible. Often expensive.

This partnership is about closing it.

Why is roaming quality still hard to measure

Roaming quality has never been just about coverage. Operators can have agreements in place, preferred networks selected, and steering rules optimized and still end up with angry customers, dropped sessions, slow data, or missing services when subscribers cross borders.

The core issue is perspective.

Most roaming optimization relies on network-level indicators, signaling data, or partner-reported metrics. These are useful, but they rarely answer the most important question: does the service actually work for the user on a real phone, in a real place, at a real moment?

That is where things tend to break down.

Roaming has become more complex, not less. 5G non-standalone and standalone coexist. VoLTE and VoWiFi roaming behave differently across markets. Enterprise and IoT roaming add new expectations. And travelers today expect everything to work instantly, because at home it usually does.

Operators need more than assumptions.

What TOMIA brings to the table

TOMIA has spent years simplifying the operational side of roaming. Its portfolio is built around automation, policy-driven decision-making, and reducing the manual effort that traditionally slows roaming teams down.

The company’s mission is clear: remove friction from roaming operations so operators can react faster to market changes, manage exceptions efficiently, and monetize roaming more intelligently.

That matters even more as operators move toward next-generation technologies like 5G Standalone, where roaming models, charging logic, and service assurance become more demanding. TOMIA’s strength has always been turning complexity into something operational teams can actually run at scale.

As Ilana Tidhar, Senior Vice President and General Manager at TOMIA, put it:

“This partnership brings together roaming innovation and independent verification, enabling operators to deliver a consistently high-quality experience from strategy and planning through real-time steering execution,”

The keyword here is execution. Steering rules and roaming strategies only matter if they work in practice.

What SEGRON does differently

SEGRON approaches roaming from the opposite direction: the end user.

Instead of relying on network probes or simulated environments, SEGRON actively tests services on real smartphones, connected to live commercial networks, across countries and roaming scenarios. This is not lab-based testing. It is a continuous, automated service verification that reflects what users actually experience.

The result is objective insight into service availability and Quality of Experience, not just theoretical performance.

Thomas Groissenberger, CEO at SEGRON, summed it up clearly:

“By combining TOMIA’s roaming expertise with SEGRON’s real-device service verification, we help the industry move from assumptions to facts when it comes to roaming quality,” .

In an industry that still relies heavily on indirect indicators, that shift from assumptions to facts is a big deal.

Why this combination actually makes sense

Individually, both companies solve important but different problems. Together, they close the loop.

TOMIA enables operators to design and automate roaming strategies. SEGRON verifies whether those strategies deliver the intended experience in the real world.

This means operators can finally connect planning, steering, and optimization with independent validation. If a preferred network underperforms in a specific city or country, that insight can feed back into steering logic. If a new roaming service is launched, its real-world availability can be validated continuously.

For MVNOs and enterprise-focused providers, this matters even more. Their roaming propositions often compete on experience rather than price alone, and they typically lack the scale to tolerate blind spots.

What this means for operators and MVNOs

The immediate benefits are practical, not theoretical.

Operators gain reduced operational risk because issues are identified early, before they turn into customer complaints or revenue loss. Transparency increases because service performance is measured independently, not just reported by partners. Decision-making becomes faster and more data-driven.

There is also a commercial angle. As roaming margins tighten and competition from travel eSIMs intensifies, quality becomes a differentiator again. Being able to prove roaming performance, not just promise it, strengthens enterprise sales, premium roaming offers, and wholesale relationships.

This is especially relevant as regulators and enterprise customers increasingly ask for evidence rather than marketing claims.

How does this compare to other players in the market

Service assurance and roaming analytics are not new categories. Players like Ookla, Opensignal, Rohde & Schwarz, and Accedian have all contributed to network testing and quality measurement in different ways. Some focus on drive testing, others on passive analytics or crowd-sourced data.

What sets this partnership apart is the combination of operational control and independent, automated, real-device verification.

Most solutions stop at measurement or optimization. Few truly connect both in a continuous loop across roaming specifically.

Crowdsourced data can show trends, but lacks consistency. Lab testing lacks realism. Passive analytics lack user context. Real-device automated testing at scale fills a gap that has been increasingly obvious as roaming services grow more complex.

A broader industry trend toward proof, not promises

This partnership fits neatly into a wider telecom trend.

Across networks, enterprises, and regulators, there is a growing demand for verifiable quality. SLAs are becoming stricter. Enterprise customers want guarantees. Regulators want transparency. End users are less forgiving than ever.

Industry bodies like the GSMA have repeatedly highlighted the importance of service assurance, especially as 5G, network slicing, and advanced roaming use cases evolve. Analyst firms such as Analysys Mason and STL Partners have also pointed out that automation without validation creates blind spots.

Roaming is simply catching up.

Why this matters now

Timing matters. Roaming is under pressure from all sides. Travel eSIM providers are educating users about alternatives. Enterprises are questioning roaming costs and reliability. Operators are investing heavily in 5G but still judged on basic service experience abroad.

In this environment, pretending everything works is no longer enough.

Being able to prove it is becoming essential.

This partnership signals a shift toward a more transparent, quality-driven roaming ecosystem where performance is measured, verified, and improved continuously, not guessed.

Conclusion: a quiet but meaningful step forward

This is not a flashy consumer launch, and that is exactly why it matters.

By linking roaming strategy with independent real-world verification, TOMIA and SEGRON are addressing one of the most uncomfortable truths in roaming: that dashboards do not always reflect reality.

Compared to traditional assurance tools or isolated testing platforms, this approach is more aligned with where the industry is heading. Toward automation that is accountable, analytics that are verifiable, and roaming experiences that can be defended with data.

If the next phase of roaming is about trust, not just connectivity, partnerships like this are a logical and necessary step.

And for operators tired of explaining roaming issues they cannot see, that alone is a welcome change.
