Truecaller launches Travel eSIM in 29 countries, powered by Seamless OS
Truecaller's first move into mobile data is live across 29 markets — plans, provisioning and billing running on one execution layer instead of a stack assembled for the launch.

Truecaller, the global platform for verifying contacts and blocking unwanted communication, has launched Travel eSIM across 29 countries. It is the company’s first move into mobile data services, and the first time digital consumables sit in a portfolio built on caller ID and spam protection.
More than 500 million people already use Truecaller in daily communication. Travel eSIM extends that relationship to international travel — a category where users routinely overpay for connectivity, or arrive at their destination disconnected.
A digital service, live in 29 markets
The service is fully digital. It activates in minutes, works on iPhone, and offers plans from 1 GB over 7 days to 20 GB over 30 days. Voice and messaging stay in the apps travelers already use — WhatsApp, FaceTime, Signal — running over the same Travel eSIM data connection.
Why it runs on Seamless OS
Seamless OS is Valdyr’s cloud-native platform for launching, managing and scaling digital mobile services. Truecaller’s plans, provisioning and billing run through one execution layer, so a new product line did not become an integration program with a launch date attached to it.
Truecaller has built one of the world’s most trusted communication platforms, used by more than 500 million people. We are proud that Seamless OS is powering their move into travel eSIM across 29 countries.
Martina Klingvall, CEO and Founder, Valdyr
Fredrik Kjell, COO at Truecaller: “I am delighted that Truecaller is launching an eSIM travel data product to our users. Truecaller is a trusted communications brand across the world, and with our scale we can offer a great product at a competitive price. We are rolling this out on our iPhone client and the web channel, but look forward to expanding with Android and adding support for additional markets.”
Where telecom is heading
The launch reflects a broader shift. Mobile connectivity is increasingly embedded into trusted digital platforms with strong customer relationships and global distribution — brands that already own the customer, and can now own the connection too.
