How to solve the problem that telecom Xiaomi 2s mobile phone can't send and receive SMS when changing to 4G card?

The processing method that the mobile phone cannot send short messages is as follows:

Method 1: You can change your mobile phone and see if you can send and receive short messages.

Method 2: If you can send and receive short messages, I suggest you plug the card back into your mobile phone and send yourself a short message to see if you can receive it.

Method 3 If not, I suggest you check whether there is a problem with the sim card;

Method 4: Check whether the number of SMS center is set correctly;

Method 5: Take the mobile phone card to the local business hall for testing or replacement.

If you don't receive SMS or verification code, it may exist in the following situations:

Situation 1, check whether the mailbox is full; if it is full, please delete some information;

After Er Ru was deleted, the situation has not been received. I suggest you change the machine or card to see if it is caused by hardware.

Case 3: Check whether it is intercepted by mobile phone interception software;

Situation 4: Check whether the cell phone signal is normal and try to test whether it can be received in other places.

After the above reasons are eliminated, it still cannot be used normally. Please contact the local manual customer service to handle this problem.
