Can I send audio messages?

Short Message Service (SMS for short) refers to the text or digital information directly sent or received by users through mobile phones or other telecommunication terminals. The number of characters that users can send and receive SMS at a time is 160 English or numeric characters or 70 Chinese characters.

Send a short message of no more than 70 words. Short message platform is relatively boring because it can only edit text and lacks corresponding picture materials, and short message advertisements are rampant, so the reading rate is not necessarily too high. The sending cost of MMS is too high.

Terminal data is difficult to collect. SMS platform needs corresponding numbers to send, and how to collect these numbers and how to send them to those customers after collection has become a very important issue, so the customer coverage of SMS platform is not necessarily comprehensive.
