If you are getting the error message "This code is no longer valid" while trying to install an eSIM, one of these three things could be the cause:
1. The activation code has expired:
eSIM activation codes usually have a limited validity period. If you wait too long before using the code, it may expire, and you may get this error message.
2. The code was already used:
Once an eSIM activation code is used to activate an eSIM, it becomes invalid. If you or someone else has already used the code, you won't be able to use it again, and you will get this error message.
3. The code is incorrect:
It is possible that you may have entered the wrong code or the code may have been mistyped. Please double-check the code to ensure you are entering it correctly.
