Is there any limit to the content of sending SMS by SMS platform?

First of all, the regular SMS platform can't send illegal content. Then we'll talk about restrictions. Restrictions usually refer to the format of the content to be sent, the presence or absence of sensitive words, the number of winding times and the time limit for sending. That's basically it. Different SMS channels have different requirements for specific restrictions. Under normal circumstances, a responsible service provider like Haoyu Information will introduce you clearly before you use SMS. Don't worry.
