Overview#
Worldwide eSIM - Stay connected everywhere.
A single eSIM card covers 150 countries, including the USA, Japan, Germany, and more. All countries can be accessed through a single digital SIM card installation. Tunz is a globally usable eSIM that, like Firsty and Yoho, offers free data access through advertisements.
1. Introduction#
Redeem your code in the Tunz app, and with just one eSIM installation, you can get free data and use mobile data in 150 countries.
Note: Its data allowance is accumulated by watching ads daily, and if the data runs out, it will switch to a 2G signal, so it cannot be used for Free Internet.
The Tunz eSIM was originally named DENT eSIM and was recently renamed to Tunz. The data should be able to be saved and accumulated for use, serving as a backup data option.

3. Conclusion#
Tunz breaks down "global internet" into daily ads: no cost, no contracts, no bills, and the accumulated data acts like a piggy bank, ready for emergencies when traveling abroad.
It may not cure severe internet addiction, but it can help you scan codes, hail rides, and send a "landed" message on foreign streets — and that's enough.
For your next journey, leave the physical card for your main number and entrust the "just in case" to Tunz; may every late-night layover have a signal light up.
