How do you know if your message has been intercepted by the other party? Expert opinion.

You can try calling each other. If you can get through, the message is definitely not blocked, because the blocked message is blocked with this number; If you can't get through to his phone, it proves that he added your phone number to the blacklist, then your message is more likely to be intercepted.

In addition, there is no way to directly know whether the short message has been delivered/intercepted. If the sent SMS is intercepted, the undelivered message will not be sent back to your inbox.

Extended data:

In order to ensure that important short messages can be delivered, it is best to test the content to be sent before sending it, and then send it.

If the system prompts that it is forbidden to send mask words, just modify the prompt words and replace them with synonyms; If the system doesn't prompt the screen words, but the test reception fails, then you can divide the short message group content into several segments and send them separately. If the content is not received, it is proved that the fragment contains the mask word, and so on until the mask word is found and modified.

When testing SMS, the mobile phone should use the same mobile phone number as the destination for testing. If you send it to Guangzhou, you should use the mobile phone number in Guangzhou to test it, because the blocking of SMS group sending is mainly aimed at the mobile phone number, and the way, words and degree of blocking are different in each region.
