Is there a company in Changsha that can send short messages in groups? Ask for recommendation

At present, there are still many platforms for sending short messages in Changsha, both good and bad. It is not recommended directly here, so as not to be suspected of advertising! You can choose local or remote. There are no strict geographical restrictions in the SMS industry, depending on channels and services.

However, when you choose, you should first look at the company's qualifications (mainly business license and SP certificate), and then talk about the price. At present, this is relatively transparent, generally at 3-6 points/article (less than 3 points is not recommended), and finally find a company that can provide free testing (see the rate and speed).
