Can the arrival rate of short message group reach 100% at present?

1. From a technical point of view, even operators can't guarantee this, because short messages must be transmitted through the Internet and wireless networks, there must be errors, and data loss will be rare;

2. From the perspective of user reception, the numbers sent by customers may include empty numbers, high-end numbers and cancellation numbers. It is impossible to receive every number, and it is normal for a few people not to receive information.

Therefore, it must be false propaganda to claim that the arrival rate of SMS group sending 100%!
