Executive Summary
A week about the plumbing of the industry rather than its headlines. Juniper Research published new figures showing travel eSIM revenue reaching 1.8 billion dollars in 2025, up 85 percent in a single year, confirming how quickly downloadable SIMs are eating international roaming. On October 14 Ericsson reported third quarter results, with sales down but margins holding as the vendor leaned on major contracts in India, Japan, and the UK. And on October 15 Samsung announced a multi-country deal to deploy virtualized, O-RAN compliant network equipment for Vodafone across Europe, starting in Germany and covering thousands of sites over five years.

Travel eSIM revenue reaches $1.8 billion in 2025, up 85 percent in one year
Juniper Research · October 13, 2025
What Happened
Juniper Research published findings that revenue from travel eSIM packages will reach 1.8 billion dollars by the end of 2025, up 85 percent from 989 million dollars in 2024. The firm attributed the surge to travelers replacing traditional roaming with downloadable local data plans, and projected that more network operators will launch their own travel eSIM offerings in 2026 to defend roaming revenue rather than cede it to specialist providers.
Atomic Take
Roaming was priced on the assumption that travelers had no alternative, and eSIM deleted that assumption. What is striking is the speed: this market barely existed three years ago and nearly doubled this year. The lesson extends beyond travel. Any mobile product priced on customer captivity, from international add-ons to device lock-in, is now exposed to a software alternative that installs in minutes. Operators with eSIM-first infrastructure can ride this wave instead of losing revenue to it.
Ericsson reports Q3 2025: sales down, margins hold on major market contracts
Ericsson · October 14, 2025
What Happened
On October 14 Ericsson reported third quarter 2025 results, with net sales of SEK 56.2 billion, down from SEK 61.8 billion a year earlier and a 2 percent organic decline. The company pointed to strong commercial momentum from major agreements in India, Japan, and the UK, and said cost discipline kept adjusted gross margins at what it called strong, sustainable levels while it continued positioning its Open RAN-ready 5G portfolio.
Atomic Take
Vendor earnings are a leading indicator for what carriers will spend next year, and Ericsson's quarter says carriers are still cautious. Shrinking sales with defended margins means the vendor market has accepted that the 5G build boom is over and is now a fight for a handful of anchor contracts. For everyone downstream, that restraint eventually shows up as networks that are maintained and optimized rather than dramatically expanded, which keeps the competitive action in pricing and service rather than raw coverage.
Samsung to deploy Open RAN network for Vodafone across Europe
RCR Wireless · October 15, 2025
What Happened
On October 15 Samsung announced an agreement to deploy virtualized RAN software supporting 2G, 4G, and 5G, along with O-RAN compliant radios, for Vodafone across multiple European countries, beginning in Germany. The deployment covers thousands of sites over the next five years and includes Samsung's AI-powered network operations suite, with Dell, Intel, and Wind River supplying the underlying hardware and cloud infrastructure.
Atomic Take
Open RAN spent years as a promising idea with small deployments, and this is what graduation looks like: a top-tier European operator committing thousands of sites to a challenger vendor for half a decade. Every deal like this chips away at the traditional two-vendor lock on Western networks, and more vendor competition ultimately means lower network costs, which flow downstream into wholesale rates. The interesting part is Vodafone using Open RAN not as an experiment but as a procurement weapon.
Trends We're Watching
- 1.The SIM is now software, and the money is following. An 85 percent revenue jump in one year is the kind of growth that turns a niche into a category, and it is being captured largely by digital-first brands rather than incumbent roaming packages.
- 2.Network vendors are trading growth for discipline. Ericsson's quarter shows a vendor market where cost control and a few anchor contracts matter more than volume.
- 3.Open RAN is quietly going mainstream in Europe. A five-year, multi-country Samsung deployment for Vodafone is not a trial, it is a supply chain decision.
Closing Outlook
The travel eSIM number is the one to sit with. Roaming was historically one of the highest-margin products in mobile, priced on captivity, and downloadable SIMs dissolved that captivity in about three years. The same dynamic, where software distribution beats physical distribution and simple pricing beats captive pricing, is now working through the rest of the industry, from how plans are sold to how networks are built. The operators that treat eSIM as their primary channel rather than an edge case are the ones positioned for where this goes.
