brief introduction

When sending a text message, it is actually sent to this so-called "short message center" first.

. Then send it to the user at the specified number through it. Usually, the number of SMS centers varies according to the number attribution. Only when the settings are correct can you send short messages normally. If the setting of the SMS center is different from the number attribution (for example, the number of city A, and the SMS center is set to the number of city B), you can only receive SMS, but not send it.
