LIVE WEBINAR ON ZOOM  ·  MVNO NATION x SEGRON

HIDDEN CHALLENGE
OF ESIM

From activation to reliable connectivity: what
every global eSIM provider needs to get right.

Global eSIM adoption is accelerating — but delivering a seamless customer experience is far more complex than a successful activation. As providers expand across operators, devices and markets, keeping connectivity reliable at scale is the hard part. This is the session that gets into it.



Join MVNO Nation and SEGRON for a practical discussion on the hidden challenges of eSIM — and how MVNOs and MNOs can get this right.

WHY ATTEND

ACTIVATION IS EASY.
RELIABILITY IS THE JOB.

Activating an eSIM takes seconds. Keeping it connected reliably, at scale, across every device, operator and market, is where most providers lose visibility and customers.

Devices

Install, activation and ongoing connectivity must work consistently across every handset, module and form factor your customers actually carry. 

Networks

Every operator and partner environment behaves differently. Every integration you add multiplies the edge cases your standard monitoring will not catch. 

Markets

Each new country compounds the problem — new rules, new devices, new failure points, and a different picture of what customers will accept. 

 

The session is built around the four stages of that problem: the failure modes your tools miss, a real operator case study, an expert panel, and open Q&A. You will leave with a benchmark, not a brochure.

THE AGENDA

90 MINUTES.
FOUR SEGMENTS.

Three working sessions and an open Q&A - each one a signal in the meter, building to the full picture.

13:00 - 13:15 | Technology presentation

eSIM perfection across every device, network and partner environment — ensuring that installation, activation and ongoing connectivity work reliably.

13:15 - 13:45 | Real-world case study

How the world's leading eSIM providers evolve their validation strategy through real-device service verification and close technical collaboration — the challenges encountered, lessons learned, and the practical approaches that keep eSIM reliable from activation through real-world customer experience.

13:45 - 14:15 | Expert panel: Maximising eSIM as an MVNO or MNO

A practical look at the complexity behind eSIM delivery — real-device service verification and the challenge of maintaining reliable service across different devices, operators and markets.

14:15–14:30 | Audience Q&A and closing remarks

Bring your own deployment and activation challenges - this is the part where you ask the people running eSIM at scale directly.
