What is the reason why Mika can make a phone call but can't send a message?

1. SMS center number is not set correctly. Please re-enter the correct SMS center number.

2. No signal or insufficient battery capacity;

3. The system is busy during the peak period of holiday SMS sending.

5. The short message sending time exceeds 24 hours;

6. The mobile phone shields the short message sending function;

7. Blacklisted by SMS;

8. Insufficient quantity balance;

9.SMS inbox and outbox are full.

1, check whether the SMS center number is correct;

2. Whether interception software is installed, which makes it impossible to receive short messages;

3. Whether sending a large number of short messages in the early stage caused the short message function to be abnormal.

4. It is suggested to try again later or avoid the peak sending period;
