Send text messages to people in batches with your mobile phone number. Each text message has a different title.

106 SMS is ok, but the mobile phone number you mentioned should not. After all, one is for business and the other is for personal use. If your personal number is unusually large, it is easy for operators to find and restrict it.

The short message using 106 can be personalized, and a variable of the title and content can be changed in batches to meet the requirements of the theme. Reply again, some sms channel can support uplink and downlink (that is, support users to reply and then send), that is, interactive chat.

The following is the reply SMS page. Many SMS companies don't have this function. You'd better ask before cooperating.
