Can the other party receive text messages after being blocked?

After being blocked, the other party is usually unable to receive text messages, but in rare cases, text messages may be displayed as undelivered due to operator network delays or technical failures. The blacklisting function intercepts communication requests through the mobile phone system or third-party software. The specific effect is related to the device model and setting method.

The blacklisting function of smartphones generally directly intercepts text messages from blocked numbers so that they do not appear in the inbox. Some Android systems will classify intercepted text messages into the trash or interception record folder, while Apple phones will completely block notifications and content. The content of text messages will not be filtered at the operator level, but if the sender receives a red exclamation mark prompt or does not show that it has been read for a long time, it usually means that the sender has been blocked. When blocked using social software such as WeChat, all messages including SMS verification codes will be intercepted by the system server.

There are special circumstances such as delays in cross-operator SMS transmission, insufficient mobile phone storage space causing the blocking function to fail, or when the blocking settings are not synchronized to the cloud, the SMS may be temporarily visible. Some dual-SIM mobile phones need to set blocking rules for the two SIM cards respectively. Missing the settings may lead to missed blocking. Overseas text messages may also break through local blacklist restrictions due to differences in routing.

It is recommended to check the interception record of the mobile phone to confirm the status of the text message. For important communication, try changing the number or contacting via email. Regularly updating the mobile phone system can ensure the normal operation of the interception function. At the same time, pay attention to whether the permission settings of the third-party security software conflict with the system interception. If you need to completely block contact, it is recommended to combine social software blacklisting and mobile phone address book blacklisting.
