2. In what kind of operation problems appear, and how to reproduce the problem ?（什么样的操作步骤问题会出现，是否是稳定复现，如何复现问题？）

{ Hello everyone. I am using the SMS example only to resive text messages. I have shortened the example but still have the same problem. The A9G starts up correctly but, after receiving between 20 or 30 messages correctly, it stopped receiving messages and the only way to re-receive messages is by restarting the module. When the messages don't arrive, I can see that other events keep running. Thanks.

This firmware has a lot of bugs and out of support 8(.
I can only suggest running clearSms in a loop :) I think that you have no space for new SMS. Some SMS can't be deleted for some unknown reason. Some can be deleted just after several tries, and here is a bug with unicode. You can find it in issues.
