How to solve the problem that mobile phones can't receive express pick-up codes?

1. Check the mobile phone network and signal: If there is no signal on the mobile phone or the network is unstable, the SMS will not arrive in time. You can try to move to a place with good signal, or switch the network connection mode, such as switching from Wi-Fi to mobile data network.

2. Check the SMS settings: Some mobile phones will set the SMS to intercept or filter status, resulting in the failure to receive the courier pick-up code. You can check whether there are filtering rules in SMS settings and turn them off if necessary.

3. Check the SMS storage space: Some mobile phones cannot receive SMS due to insufficient SMS storage space. You can try to clean up some useless messages or increase the storage space of your mobile phone.

4. Contact the customer service of the courier company: If the above methods can't solve the problem, you can contact the customer service of the courier company to explain the problem and provide relevant information, such as mobile phone number and order number, so that the customer service can help you inquire and provide solutions.
