Unicom received several messages for one message.

Unicom's short message is a 70-character short message, and some mobile phones can input many characters, so the system will automatically send a 70-character short message after sending. If the problem occurs when you enter less than 70 Chinese characters, please feel free to dial 100 10 and press 0 according to the prompt. If you overcharge, you will definitely get a refund. Unicom is a big company. If it is because of their system problems, it will definitely be returned to you. I tried to complain, but I found out at that time that the number of short messages I sent was 560 Chinese characters, so there were several short messages. If in doubt, you can directly consult 100 10. I think you can solve them faster. Calling 100 10 is free.
