My short message can't be activated, and I can't get a message.

If it is mobile, you can call customer service 10086.

If it is telecom, you can call 10000 customer service for inquiry and handling.

If it's not the mobile phone card, you may have misadjusted the mobile phone settings to disable SMS, but the probability of being disabled by you is still quite high. You can click on mobile phone settings or mobile phone software management to check whether permission settings are disabled.
