Which is faster in Chengdu SMS sending platform?

Don't just pursue speed. Depends on what you got. If you send a verification code, you must pursue speed, because the verification code will be invalid after a long time. If you send an urgent notice, you should also pursue speed, which may delay things. But if you advertise for speed, you are wrong. Advertisements are generally put in large quantities. The SMS platform will give you the so-called * * * access channel, and other users will have a certain delay when using it. Recommend Haoyu Information Communication and Dada. Good platforms will be accurately classified. They know exactly what to promise and what to do.
