How can there be two messages at the same time? Is there something wrong with the phone or the card?

1. Try calling customer service. What is the reason?

2. The phone card problem.

3. Mobile phone problem

4. The network problem is that when sending the first message, it takes a long time because of network buffering, but the mobile phone regards this message as a sending failure and resends it. At this point, the first message has just been sent successfully, but the second message has also been sent, resulting in the situation that the same message sends two messages.

I hope I can help you!
