Which platform is better for SMS verification code? The best in Nanjing?

Those companies are doing well in the SMS industry, but some time-honored companies have sold their companies and switched to other industries. Now recommend the eight-step SMS platform. It seems that they started out as software outsourcing, and later made their own information service platform, which also brought short messages. 14 years, they carried out major reforms, separated the mobile communication business and focused on enterprise-level communication services. The technology, channels and support of this company come from people with more than ten years of experience in the same industry. The classmate company has cooperated with them for two years, which is relatively stable and has not had any problems. The following are some mobile phone numbers given by their company that can't receive the verification code. You can collect them:

(1) The mobile phone is equipped with interception software;

(2) The mobile phone is turned off, and there is no signal for the time being, and it is overdue or stopped;

(3) The mobile phone did not switch from the off state to the normal state after being recharged due to arrears;

(4) The user has set a blacklist on the operator side;

(5) The mobile phone cannot receive short messages with a length of more than 70 words;

(6) The mobile phone is used abroad or used abroad;

(7) The SMS is kept intact;

(8) Mobile phone network and operator failures exist in some areas;

(9) Sending SMS more than once.

There are many words, but I hope they are useful to your question.
