What is the problem with incomplete reception of sent messages?

This is a network problem. The short message sent to you by the other party is very long, and your mobile phone can't display such a long piece of content in a short message during transmission, so you can only see half of the short message. Your card is Unicom, so send text messages to mobile users to compress the content as much as possible. Sometimes the two networks are not in the same area, so the acceptance is incomplete. In view of this situation, you can call the technical department for consultation, or call the Unicom service number and ask the operator over there. This is not a big problem, it is easy to solve.
