Truecaller is pivoting hard. The caller ID company, once known primarily for blocking spam calls, just launched eSIM services for international travelers. On the surface, it looks like a smart diversification play. Dig deeper, and you see a company in survival mode.
Last week, Truecaller cut 70 jobs. The week before that, it reported Q1 2026 numbers that made investors wince: net sales dropped 27% to 362 million SEK (roughly $39.34 million), while ad revenues crashed 44%. When your core business is hemorrhaging that badly, you either innovate or you shrink. The company is choosing innovation, whether it works or not.
The eSIM launch makes a certain kind of sense. The company has 500 million monthly users, a userbase most startups would kill for. By offering travel data plans directly inside the Truecaller app, the company doesn’t need to build an audience from zero like competitors such as Airalo, Holafly, and Roamless have had to do. “These are established relationships, with a large number of people having used Truecaller for many years. That changes distribution and pricing,” the company’s chief operating officer Fredrik Kjell told TechCrunch.
That’s not wrong. But it’s also not a guarantee.
The Crowded Playground
The eSIM market is genuinely hot right now. Adoption is climbing thanks to wider device compatibility and the rise of remote work and travel. Investors are pouring money into the space. Startups like Airalo, Roamless, Kolet, and eSIMo have all raised millions in the last year. The tailwind is real.
But so is the competition. Truecaller isn’t entering a vacant market. It’s entering a market where several well-funded, specialized players already exist. These competitors aren’t distracted by imploding ad businesses. They’re laser-focused on eSIM. They’ve built entire companies around this single product. Truecaller, by contrast, is adding eSIM to a caller ID app as a Hail Mary.
The company’s data plans are modest by eSIM standards: 1 GB over 7 days up to 20 GB over 30 days. Initially available in 29 countries, the service is noticeably absent from India, Truecaller’s largest market, due to India’s strict telecom regulations that previously blocked rivals like Airalo and Holafly over fraud concerns.
The Real Problem
Here’s the uncomfortable truth: eSIM services have thin margins. Success requires scale, network effects, and efficiency. Truecaller has scale within its existing userbase, but launching in 29 countries is a global operation. That requires infrastructure, partnerships, regulatory compliance, and customer support across multiple regions and languages. It requires a team obsessed with telecom. Truecaller is a caller ID company that just fired 70 people.
Yes, the company is working with established partners. It’s partnering with Telna for cellular connectivity and Telness Tech for telecom software. That’s sensible outsourcing. But outsourcing doesn’t eliminate the execution risk. The company still needs to market the product, handle customer issues, manage churn, and compete on pricing.
More importantly, eSIM services are a discretionary purchase for most users. Truecaller’s core product, spam call blocking, solves an immediate pain. eSIM plans solve a need only when someone travels internationally. The funnel is narrower. Conversion rates will likely be lower than the company hopes.
The Broader Strategy
What’s really happening here is that Truecaller is trying to shift from an ad-revenue company to a subscription-revenue company. The eSIM launch sits alongside other bets like AI Assistant and Family Protection features. None of these individually seems revolutionary. Together, they represent a pivot away from advertising, which makes sense given how badly that revenue stream has deteriorated.
The problem is that pivots take time, and Truecaller doesn’t have much runway. Missing India, your biggest market, because of regulatory barriers is a meaningful constraint. It means you’re fighting with one arm tied behind your back. The addressable market is smaller than it could be.
That said, Truecaller’s 500 million user advantage shouldn’t be dismissed. If even 2 to 3 percent of those users buy an eSIM plan once a year, the numbers could add up. That’s not a replacement for lost ad revenue, but it’s real money. The company might make this work, not because eSIM is a magical business, but because it has the distribution to avoid complete failure.
The question isn’t whether Truecaller can survive this pivot. It’s whether it can execute it well enough to restore investor confidence while simultaneously rebuilding its core business and fending off better-capitalized competitors in a market that punishes anything less than excellence.
