The mobile phone number has been blacked out. Can you still get the message?

When the number is pulled, the short message with black hair can be received by the other party.

After the mobile phone is hacked, the information can be transmitted. However, due to the different settings of the other party's mobile phone and blacklist, and the different mechanisms between different mobile phone systems, most Android systems will have interception records, while Apple phones will not.

In the first case, the mobile phone is hacked, and the other party's mobile phone can receive the short message you sent. Because it is blocked, your message will not appear in the message list.

In the second case, some Android phones will display interception reminders when they receive short messages with blacklisted mobile phone numbers. When they receive a short message from a hacked mobile phone number, the notification bar will show that a short message has been blocked. At this point, click the intercepted short message to enter the short message application interface, and you can directly open the intercepted short message to view the content.

How SMS works:

The implementation principle of SMS-ShortMessageService is simple, but the process of inputting text on mobile phone is troublesome. The first is the store-and-forward mechanism.

Sending data packets by SMS is done by the short message center in the mobile network instead of the end user. If the user is not in the service area, the short message is stored in the short message center and forwarded to him after the user appears, which is not available in GPRS and other services.

The second is the delivery confirmation mechanism. In the circuit-switched data environment, the connection is end-to-end, so users can know whether the connection is completed and data transmission, but in the GPRS environment.

The terminal connected to the GPRS bearer is always online, and it is always ready to send or receive data transparently (relative to the user). In this way, the task of checking whether the data packet is sent successfully falls on the user, and the cost of each corresponding packet data service will be higher than that of SMS.
