How to choose SMS platform

First of all, the short message sending platform is based on the short message ports directly provided by China Mobile, China Unicom and China Telecom, and is connected with the Internet to realize batch sending and customized sending of short messages with customer-specified numbers. Short message service depends on its channel, arrival rate, arrival speed and whether it is directly connected with operators. Of course, these are also based on your own needs. For example, if mass texting is inefficient, you can choose the regular version, and if you pay attention to timeliness, you have to choose those high-end channels. This requires careful understanding and analysis of each platform. I'm using the short message service of the letter reading platform now, and it feels good.
