Does anyone know the price of mass messaging in Luoyang? What is the promotion effect?

I personally recommend Luoyang Zhong Hao Media. They can send it to your designated person according to your needs. They support SMS color service. Nowadays, many companies use this group SMS software to promote their products, mainly because of its convenience and low cost. I hope it helps you! What is the specific monthly price? I don't know what your request is, just ask.
