What is the reason why the other party can't receive the short message sent by China Telecom's business navigation platform?

Dear users, hello! Thank you for your support to Telecom!

China Telecom's business navigation platform sometimes fails to receive short messages when sending them, mostly because the short messages contain sensitive keywords of telecom companies.

The treatment method is as follows:

First, adding punctuation or spaces among keywords is not effective at present.

Second, it is effective to change simplified to traditional, but some mobile phones do not support traditional websites.

Third, removing keywords has a good effect.

Fifth, when using digital mask, the number is changed to full-angle number, and the effect is good.
