What should I do if my Le 2 phone cannot send text messages?

According to the description of the situation, there are two situations:

1. The mobile phone has security software settings to intercept text messages. Find and modify such software, or try using another mobile phone.

2. Troubleshoot the problem with your mobile phone. This means that your mobile phone sent too many text messages in a short period of time, and was judged by the system to be sending spam text messages and was turned off. Call customer service or bring a mobile phone card to the business hall. After the demonstration, the customer service will contact the background data to search and solve the problem.

Please accept the satisfactory answer if it helps.
