Whenever I restart my mobile, my internet APN gets deleted automatically, I have to create APN again and again, why is this happening? In Samsung Galaxy S21 Ultra

(SM-G998U/DS)

This issue is phenomenal with locked US versions after the android 14 update. Therefore, you have to flash unlocked firmware XAA version via odin. 

Warning: you have to choose CSC Home instead of regular CSC file in order to not wipe your date 

The firmware + odin tool links and instructions in the below page :

My CSC Firmware Is Not U1 Sir.. U1 is locked And 5G Will Not Work..

You can flash U1 firmware on U version. This is the only solution for now unless you contact Samsung US and inform them with the issue that has been excited for a year. Unfortunately Samsung takes longer time to solve several bugs and technical support can't address the issues

Also you there is a workaround for this issue.  Can you put your device on an airplane mode before rebooting your phone
