Problem:

After phone clone, the number of SMS Messaging becomes less. SMS Messaging concerning verification codes fail to be transferred from the old phone to the new one.

Cause:

This is because you have enabled the Verification code security feature on the old phone, which prevents the new phone from obtaining SMS Messaging containing verification codes.

Solution:

You can go to Messaging > > Settings > Advanced, and enable or disable the Verification code security feature as needed.
