Why is the new number starting with 198 successfully sent to others, but the empty number cannot be sent, and there will be a prompt?

No matter whether it is a new card or an old card, the empty number cannot receive the short message content. An empty number means that the other party has not activated this number and has no right to send and receive text messages and make phone calls.

When you say that the old card can be sent successfully, it only means that you have successfully submitted the SMS on your mobile phone, but the sending result does not mean that you have succeeded. Now the new card has some signal recognition functions. If the other party's number is empty, it will fail to send directly, with a red exclamation mark.

Like the current regular 106 short message group sending platform, it supports one-click group sending. The sender displays the port number beginning with 106. If the other party's number is empty, it will also fail to send. There will be a return value in the gateway background, and the platform menu can query the specific sending and receiving situation.

Whether it is a personal card or an operator's mass sending channel, the empty number will fail to be sent, which belongs to the number problem.
