Why can't I get the message starting with 106 from the SMS platform?

First, let's see if the mobile phone software intercepts the short message in the trash can. If not, then let's see if the mobile phone number is blacklisted by the operator, and the blacklist cannot receive short messages. Another situation is that there is a problem with the channel of the SMS platform itself. Only in these three cases, in fact, a good platform can check the receipt status. Take Haoyu Information Communication as an example. After sending, you can check and track the sending status of each item. If it is not received, a code will be generated, through which we can analyze why it is not received.
