My friend Didi Didi received the text message and could not open it.

The phone is stuck or the memory of the phone is slow.

You can try to shut down and restart the phone or clean up the phone memory to make the phone memory have buffer space. If the memory is too small, the phone will cause the card machine to crash and other reasons.

The method for Didi to receive friends' short messages is to open Alipay, search to enter Didi Travel menu, select login mode, enter Didi Personal Center interface, click on the top left avatar, select the security menu below, find the emergency contact in the middle, and continue the next operation according to the prompts. After entering, you can see the set emergency contacts, click the management settings menu on the right, then click the new option, enter the corresponding mobile phone number and other information, click the open automatic sharing itinerary option, and you will receive a short message prompt after taking a taxi.
