Why can't LeTV 1 receive some short messages?

You can check whether the mailbox is full first. If it is full, please delete some information.

If you still can't get it after deleting it, you can change the machine or card to see if it is a hardware factor.

After eliminating the above reasons, you can try to test whether it can be received in other places to see if it is the reason for the weak local signal.

SIM takes it to another machine to try. If it can be received normally, it means that it is the machine itself or the SIM. Call 10086. If there is an error in this machine, first run process management, end all processes without gears, and then delete this file in the C:/SYSTEM/DATE directory, and then restart it.

Replace the mobile phone card and test whether it is a mobile phone problem or a card problem. If it is a mobile phone problem, it is recommended to send the mobile phone to the after-sales outlets for specific testing.

Cell phone crashed, try to turn it off and restart.

If none of the above problems exist, it may be related to the network function, please contact the local manual customer service to deal with this problem.
