Is there a free SMS platform provided by China Net Construction?

The sending of short messages, whether through personal mobile phones or through regular gateways, has to go through operators, and there is a cost. It's not free. If there is free news, you need to use your data or for other reasons. I believe that there is no such thing as a free lunch, and the cost of a short message is not much. Many SMS platforms support free testing, but the number of free messages given to you is limited. You can learn about it on Baidu.

I hope my answer can help you.
