Frequently Asked Questions (FAQ)

1. How do I choose the right travel eSIM?

Select a plan based on your destination, trip duration, and expected daily data consumption. Contact our support desk if you need a customized recommendation for multi-region trips.

2. Can you check whether my mobile device supports eSIM?

Yes. Open your phone dialer app and enter *#06#. If an "EID" barcode or a 32-digit number displays on your screen, your device hardware natively supports eSIM.

3. When is the best time to install my travel eSIM?

We recommend setting up the eSIM profile configuration while connected to a stable Wi-Fi network before your departure, following the activation instructions provided in your delivery email.

4. Where can I find official setup guides and compliance information?
