Why Are We Affordable?

Unlike airport kiosks or travel agencies, we've fully automated everything. Your eSIM QR code is delivered instantly via email the moment you purchase. With no physical stores or staff overhead, we pass the savings directly to you - offering carrier data at minimal margins.

Why Are We Safe?

We exclusively sell data-only eSIMs designed for travelers. Unlike some providers who issue SIMs under someone else's identity, our eSIMs require no personal registration. You can use them legally and safely without any privacy concerns.

Why Are We Special?

We offer fully automated top-up functionality. Start with an affordable plan, and if you need more data, simply top up anytime. Each top-up also extends your validity period - no need to purchase a new eSIM or go through setup again.

Is It Fast?

Each eSIM connects directly to the country's most popular carriers with no speed throttling. The only exception is daily unlimited plans - after your daily quota, you can still use data but at reduced speeds.
