Shows 4g but no connection

본문:

Hello

today i have a customer that has a problem with the 4g.

the person cannot use the internet, so i tried my sim card and the connection works for a minute, after that the internet turns off but connection is visible.

i try to reset network settings but it did not work.

what could this be?
