Truecaller has launched a travel eSIM service in 29 countries as a new revenue stream amidst a significant slide in its advertising income.

• Truecaller, known for its call-screening app, is now selling mobile data plans for travellers.
• This move comes as the company reported a 27% drop in net sales in its Q1 2026 results, with advertising revenue falling 34% in constant currencies.
• The launch is seen as an effort to diversify revenue sources beyond advertising, particularly after facing challenges in its largest market, India, which is notably absent from the initial eSIM launch.
