I don't know why I can't get the short message of 100 10 on my mobile phone.

The reasons why the mobile phone failed to receive the SMS are: 1. I suggest you check your mobile phone before you can make a normal call. If you are prompted to owe money, you can use it again after paying; 2. The SMS storage is full. If the inbox of the mobile phone is full, you can't receive new messages. It is recommended that you empty your inbox and try again. 3. Incorrect setting of the SMS center number leads to the problem that the SMS center number cannot be set correctly in the mobile phone information setting (the correct SMS center number can be inquired by the customer service of the operator to which the mobile phone card belongs); 4. The poor signal of the location leads to poor signal in tunnels, tunnels, deep mountains or sparsely populated places, and the mobile phone can't receive short messages. Or in other places, but the instrument with signal shielding shields the cell phone signal, so it is temporarily unable to receive the information. As long as you change your position and go to a place with good signal, you will naturally receive the information you didn't receive; 5. Set the blacklist and information interception to see if the other party's number is set to the SMS blacklist. If this is the case, just publish the wrong blacked-out number; 6. If the mobile phone card operator has network problems, you can call the customer service hotline of the mobile phone card operator for feedback; 7. Mobile phone hardware/system problems, maybe the mobile phone is out of order. You can restore the factory settings of the mobile phone and try again (you need to back up the important data in the mobile phone in advance), or contact the mobile phone for after-sales inquiry.
