Important note
■ Before You Use
• Please ensure your device supports eSIM and is carrier-unlocked.
• The eSIM can be installed in advance. To avoid activating the plan early, connect to a supported network only when you are ready to use it.
• Once installed, the eSIM is linked to your device and cannot be transferred to another device.
• If the eSIM is removed, it can only be reinstalled on the same device.
• After successful installation, scanning the same QR code again may display an error message.
■ Activation & Usage
• To receive SMS messages or verification codes on your original number, keep your original SIM card or eSIM active and set it as the default voice line.
• To avoid unexpected roaming charges, turn OFF Data Roaming on your original SIM card or eSIM.
■ Additional Information
• Network speed, coverage, and 4G/5G availability may vary depending on location, network conditions, and device compatibility.
• Some apps and services may be unavailable due to regional restrictions or provider-specific policies.
FAQ
How do I find out if my phone supports eSIMs?

1. Dial *#06# in the phone call interface. If an EID is displayed, it indicates that your phone supports eSIM. Without an EID, an eSIM cannot be used.

Where can I find the EID and IMEI on my phone?
The EID functions as a digital signature that links devices to mobile networks, typically comprising 32 characters, which include both letters and numbers. The IMEI, or International Mobile Equipment Identity, serves as a unique identifier for your phone and is generally 15 digits long.
For iPhones, you can find your EID and IMEI by going to "Settings" > "General" > "About" > EID/IMEI. Another quick way to find your EID and IMEI is by dialing *#06#, which will display a screen with your device information.
For Samsung phones, go to "Settings" > "About Phone" > "Status Information" > IMEI/EID

How do I activate a renewal?
For total volume-based eSIMs, the renewal will automatically activate after the first plan has been completely used up. You don't need to scan the code again for installation. Once the first plan is used up, refresh the network, wait a few minutes, and it will automatically renew for you.
For daily-based eSIMs: The renewal booking will automatically activate after the days covered by the first booking's package have used up. You don't need to scan the code again.
Additionally, if you want to use eSIM on a different phone, please do not place a renewal booking, as renewal bookings do not support changing phones.

Can I still purchase your service if I have already activated an eSIM on my phone?
Yes, your phone can store multiple eSIM profiles at the same time. You can choose which one to use in your phone settings.
