Which third-party service providers do you use for SMS verification code?

There are two general SMS verification code services:

Directly cooperate with China Mobile, China Unicom and China Telecom, each of which can be handled in the local business hall. However, if the short message traffic required by operators is relatively high, it will be easy, because they mainly develop large-channel customers, code number landing, information and data diversion and other services. This method is not recommended for small and medium traffic.

The enterprise company that has obtained sp certificate (namely telecom value-added service license) has access to the gateway interfaces with the three major operators, and also has the qualification of a third-party SMS service provider. And has its own independent code number and stable sms channel. Only in this way can we ensure the achievement rate and success rate of SMS verification code.

To find a safe and reliable SMS verification code, third-party service providers should not only review the qualifications and conditions expressed above, but also listen to the reputation of users in the same industry and compare prices. If the required SMS verification code service is large and lasting, it is suggested that it is best to inspect the scale conditions of SMS service providers on the spot. In order to avoid the suspicion of advertising, we can understand it first and then cooperate.
