Accepted Answer

The EID can be seen as a digital signature that connects devices to mobile networks, typically consisting of 32 characters, a combination of letters and numbers; the IMEI is the International Mobile Equipment Identity, which can be seen as your phone's fingerprint, usually 15 digits long.
For Apple Iphones: 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: Settings → About Phone → Status Information → IMEI/EID.

Question 7

How to activate a renewal order?

Accepted Answer

For total volume-based eSIMs: The renewal order will automatically activate after the first order is completely used up; you don't need to scan the code again for installation. After the first order's plan is used up, refresh the network, wait a few minutes, and it will automatically renew for you.
For daily-based eSIMs: The renewal order will automatically activate after the days covered by the first order'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 order, as renewal orders do not support changing phones.

Question 8
