Why do I send text messages in groups, and only one message is sent on a mobile phone? Why am I sending two messages backstage?

According to the information you provided, it is not excluded that the short message you edited exceeded the maximum number of characters of a single short message, resulting in sending 2 short messages. A short message can be sent at most 70 Chinese characters or 140 characters at a time, and it can be sent beyond this number, but the other party will receive multiple messages, and the cost of sending a short message will be charged according to the number of messages received by the receiver. For details, it is suggested to contact the Unicom customer service to which the number belongs.
