Chongqing Mobile Card failed to make a phone call, and no phone calls or text messages were received.

You can put the card in another mobile phone and try again. If there is no signal, it can basically be confirmed that the mobile phone card is damaged and needs to be reissued in the business hall. If there is a signal, but you can't answer the phone and send a message, it may be that the network is not good at that time, and the mobile phone shows a false signal, so you need to call the customer service hotline to reflect the network signal problem. In addition, you can also take your mobile phone card to the local business hall and ask the staff to help you test it.
