Business eSIM: the end of the corporate phone

A second identity, not a second device

A business eSIM embeds a company-controlled phone number directly into an employee's existing smartphone — no app to open, no second handset to carry. The employee dials from their native phone dialer; the company gets full oversight. The personal number and personal privacy stay completely intact.

The difference from a consumer eSIM is what happens behind the number. A business eSIM routes the line through the company's cloud platform, which means every call can be recorded, transcribed, AI-summarised and synced to the CRM automatically. The eSIM does not replace the phone — it gives the phone a second identity that the company controls.

The blind spot is bigger than most leaders think

Over 82% of organisations now allow some form of BYOD, yet most have no visibility into the business calls made on those personal devices. That is not flexibility — it is a blind spot. A deal negotiated on a train, a delivery date promised by a technician, a price agreed over lunch: from the company's perspective, those calls never happened.

The cost is not abstract. It shows up in deals nobody can trace, in compliance failures that draw fines, in disputes where the company has no record of what was said, and in sales teams whose performance cannot be measured because the data does not exist. Regulators in financial services and healthcare increasingly require business communications to be captured and archived — and have levied serious penalties on firms that failed to record employee conversations on personal devices.

Why this beats corporate phones and softphone apps

Corporate phones are expensive to buy, ship, manage and recover, and many staff simply leave them in a drawer and use their personal phone anyway. Softphone apps look better on paper, but busy employees default to the native dialer because it is faster — every call made outside the app is a call the company never sees. A business eSIM removes the friction entirely: it is the native dialer, so there is nothing to adopt.

• No app required and voice calls don't consume mobile data
• Every call routed through the platform for recording, AI and CRM sync
• Local presence with numbers from multiple countries
• Setup in minutes — scan a QR code, no configuration
• Internal calls between colleagues are free
• A new hire provisioned — or a leaver deprovisioned — in minutes

Why now: the market has tipped

Business eSIM is not a concept waiting for the market to catch up — the market is already here and accelerating. Projections put eSIM cellular connections at around 4.9 billion by 2030, up from roughly 1.2 billion in 2025, with the global eSIM market growing at a double-digit compound rate through the next decade.

Device readiness has caught up too: most flagship smartphones now ship with eSIM as standard, and a growing share are eSIM-only with no physical SIM slot at all. With over 200 mobile operators worldwide supporting eSIM, the conditions for a business rollout are finally in place — and 2026 is the year the corporate phone starts to look like an artefact.

From invisible calls to actionable intelligence

Once business calls run through one platform, conversations become data. Managers can see activity, coach from real recordings instead of memory, and keep an audit-ready archive — turning the most important customer moments from a blind spot into a measurable, defensible record.

There is a second dividend: AI sales coaching, sentiment analysis and call intelligence are only as good as the data they receive. Calls made on personal phones are invisible to those systems. Route them through a business eSIM and the whole AI layer suddenly has something to work with.
