Aribi SMS sdk is big.

As an SMS verification code platform service provider, 15 is an old brand, so I won't go into details. I boast that there are not many brand enterprises that meet the above conditions of stable service, high speed, high rate and low price with many years of industry operation experience. 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. First of all, I recommend Huaxin platform: as a short message channel service provider with a history of 15, Huaxin short message platform is an old short message service provider in the short message industry. The platform channel service is stable, the SMS arrival rate is as high as 99%, the SMS seconds arrive, the customer experience is good, and because of 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, it is suggested that Monternet has a 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 (for example, Nokia can use mobile phones as bricks) have an impression of Monternet.

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

Pay attention to the following three points when choosing SMS verification code platform:

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

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 rate and users are lost.

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