Important Carrier Message notification EVERY DAY!!!!!!

If some app push notifications frequently, I will disable the notification or sound.

"important carrier message" should give an options to be muted too.

This is ABSOLUTELY an apple issue.

Since app can be removed, but sim card can't be removed.

The carrier message I get in English is “Dear users, welcome to use China Unicom's services“.

I think the message is when iPhone disconnect from the carrier, then at som time reconnect to the carrier, then get the welcome message.

It's just a welcome message from the carrier. the message has been many years. they won't remove it just because iPhone iOS version 15 has this bug.

And, I don't need a carrier update, and there are no carrier update instructions at Settings > General > About.

In addition, from wikipedia: China Unicom is the third-largest wireless carrier in China, with 310.45 million subscribers as of June 2021.

Today I have upgrade to iOS 15.5, but I still get this message with sound.

I still can't find a way to disable the sound.

WTF!!!!!!!

It's now late night(UTC+8).

I am disturbed by the sound AGAIN.......

was disturbed again at 00:19......

01:26 again

this is not the problem of carrier

there are no such issue people using Android, or iPhone before iOS version 15

There are lots of complaints on Chinese social media about being disturbed multiple times by this message when asleep at late night.
