TL;DR: Opera added a built-in travel eSIM to Opera One for Android on September 29, 2026. The launch includes a free 3GB data trial valid for three days across 47 destinations, with paid 3GB, 5GB, and 10GB bundles offered through Holiday.com.

Opera added a built-in travel eSIM to Opera One for Android on September 29, 2026. The browser includes a promotional trial with 3GB of mobile data valid for three days across 47 destinations.

The eSIM provides cellular data access for the whole Android device, not just the browser. Opera said users can set it up inside the app without a credit card or email verification, and the trial starts only when the user arrives abroad and connects to a supported local carrier.

Opera said the service operates in partnership with Holiday.com. After the free trial, users can buy 3GB, 5GB, or 10GB data bundles with 30-day validity, and purchased packages remain redeemable for up to one year before departure.

The feature requires a carrier-unlocked smartphone running Android 10 or newer with eSIM support. Opera said the offer is available in Opera One for Android, not Opera Mini or Opera GX, and that the service is data-only, so voice calls require VoIP apps.
