Why can't I get the SMS from the mobile company on my mobile phone? For example, if you check the phone bill, you won't get the text message.

The short messages of mobile companies are very, very likely to be intercepted by the software of your smart phone, such as mobile phone security guard, new wing, 360 mobile phone guard and so on. You can check these messages in the interception records of these software. If I guess correctly, your mobile phone should be a smart phone.

To solve this problem, you can set the SMS number as a white list in the software, and the white list will not be intercepted.
