Are there any cost-effective companies in Chongqing in the mass short message platform? Ask for recommendation

There are many platforms that offer free testing opportunities, such as PaaSoo. You can test it and analyze it from the factors such as price, arrival rate and delivery speed.

Another point is that the SMS platform has no geographical requirements, and it can generally be docked online.
