Ali is bigger than SMS api.

As the service provider of SMS verification code platform and the old brand of 15, I won't be here. I boast that with my years of experience in industry operation, there are not many brand enterprises that meet the above conditions, with stable service, fast speed, high rate and low price. I think the landlord should ask the well-known SMS channel service providers with high cost performance in the industry. The following is a simple recommendation of 1. I. Recommend Huaxin Platform: As a SMS channel service provider with a history of 15, Huaxin SMS Platform is an old SMS service provider in the SMS industry. The platform channel service is stable, the SMS arrival rate is as high as 99%, the SMS seconds arrive, and the customer experience is good. Due to the SMS operation for many years, the SMS sending cost is relatively low. At present, there are branches in Beijing, Shanghai and Shenzhen, and there are responsible regional managers all over the country.

2. Secondly, Monternet has a very long history in the industry. Maybe many people don't know what non-smart phones look like now, but people who use non-smart phones (such as Nokia can use mobile phones as bricks) still have an impression of Monternet in mobile phones.

3. Finally, recommend Alibaba Cloud, a short message company with good reputation and cost performance in the industry.

Choose SMS verification code platform should pay attention to the following three points:

1, speed, SMS verification code free test platform, users can continue to register, log in or other operations after sending the verification code, so the verification code arrives at a relatively high speed, and you can choose if it can reach about 3 seconds. It is recommended to try it first and see the arrival speed of the verification code.

2. Arrival rate. Generally, the arrival rate of verification code is required to reach more than 99%, and the acquisition cost of each registered user is often tens or hundreds of yuan. Unfortunately, the verification code can't reach the speed, and users are lost.

3, stability, the instability of the verification code will seriously affect the arrival rate and speed, users may need to verify the phone at all times. Poor stability will lead to the failure to receive the verification code, which will affect the user experience.
