Truecaller Expands Beyond Caller ID With a Travel eSIM Service

Instead of traditional roaming, users purchase a temporary data plan tied to a destination and activate it when they arrive.

Key features include:

• Digital installation with no physical SIM swap
• Ability to keep the phone’s primary SIM active for calls while the eSIM handles data
• Data connectivity activated automatically upon arrival in the destination country

Voice and messaging continue through internet apps such as WhatsApp or FaceTime using the purchased data plan.

Data plans and global coverage

Truecaller’s launch focuses on short‑term travel connectivity rather than full telecom subscriptions.

Available plan ranges include:

• 1 GB for 7 days
• Up to 20 GB for 30 days

The service supports connectivity in more than 150 countries, allowing travelers to purchase new destination plans without reinstalling the eSIM each time.

At launch, the product is available across 29 countries, including markets in Europe, North America, and Oceania. Examples include:

• United States
• United Kingdom
• Canada
• Australia
• Sweden
• France
• Germany
• Italy
• Spain
• Netherlands
• Switzerland

India—Truecaller’s largest market—is not included in the initial launch, likely due to stricter telecom regulations for eSIM and roaming services.

Technology partner behind the service

The travel eSIM is powered by Telness Tech’s Seamless OS, which provides the underlying telecom infrastructure used to activate and manage the digital SIM service.

This allows Truecaller to enter the mobile data market without becoming a full telecom operator itself. Instead, the company layers a connectivity product on top of its existing global user base.

Target users: international travelers

The service is designed primarily for international travelers who need mobile data abroad but want to avoid high roaming fees or buying local SIM cards.

Typical users include:

• Tourists visiting multiple countries
• Digital nomads and remote workers
• Business travelers who need immediate connectivity upon arrival

Because installation takes only a few minutes and works before landing, travelers can activate data without visiting airport kiosks or retail stores.

Why Truecaller is expanding beyond caller ID

The travel eSIM launch comes during a difficult financial period for the company.

In Q1 2026, Truecaller reported:

• Net sales down 27% year‑over‑year to SEK 361.6 million
• Advertising revenue dropping sharply, contributing to declining overall revenue
• India revenue falling 41%, hitting its largest market particularly hard

The company’s profitability also suffered, with EBITDA declining significantly during the same period.

Advertising has historically been a major part of Truecaller’s business model, but shifts in the digital advertising ecosystem and changes in partner algorithms have reduced ad income.

Launching a travel eSIM creates a transaction‑based revenue stream that is less dependent on advertising impressions.

Leveraging a massive global user base

Truecaller still has a huge audience. In early 2026, the platform reported around 463 million monthly active users and 403 million daily active users worldwide.

By adding telecom services like travel data plans, the company can monetize that user base in new ways:

• selling connectivity services to frequent travelers
• bundling travel features into the app ecosystem
• expanding into telecom‑adjacent services beyond caller identification

A broader shift toward recurring and service revenue

The eSIM launch fits into Truecaller’s broader push toward recurring and diversified revenue streams, including premium subscriptions and business communication tools.

While it remains early to judge the commercial impact, the travel eSIM initiative shows how the company is experimenting with telecom‑adjacent products to reduce reliance on volatile advertising income.

If successful, the move could position Truecaller not just as a caller‑ID platform, but as a broader communication and connectivity service provider for its global user base.
