Which is better to send SMS verification code API?

The quality of SMS authentication mainly depends on the user experience. The main problem lies in the channel quality and technical processing ability of SMS platform. In general, the regular channels in short message channels are all triple play channels of 1069, and the processing capacity of sending messages at 500- 1000 per second is basically sufficient. Everyone has different opinions about the price of SMS, which is generally around 5 points. The price of Chuanglan 253 platform we access is almost your price. More than that, several people think it has exceeded the standard. If there is demand, you might as well look at the quotation first and then test it, so that you can have a little confidence. I know that the cost of innovation is high, and no one wants to be disgusted at this point.
