Why can't I get the message after I turn it off?

You turned off your phone for a week and didn't receive a text message from the courier company, which may be caused by the courier company not sending a text message. Usually, short messages are stored on the server, which has certain timeliness. If the time limit of local Unicom is exceeded, the target number is still in an abnormal unreceived state, and the short message may not be sent, resulting in your failure to receive the short message. I suggest you contact the customer service in your hometown for consultation and understanding, which is subject to the local Unicom policy.
