I bought a mobile phone card, but I can’t make calls or send text messages. It always shows that there is no network service.

The card itself cannot display the local number unless the card is installed and the call is made to other mobile phones, so that the number can be displayed on other mobile phones. If you can't make a phone call, just bring your ID card and card. Do you have a card holder? The SIM card should be broken off from the card holder. There is a customer service password on the card holder. If you have a card holder, take it with you to the mobile business office. The business office can put your card into the machine for testing and can also inform you. Your card number.

If the card is broken, you can replace it directly at the mobile business hall.

Business halls generally work from 9:00 to 19:00. You can call 10086 and press 0 to call manual to find the business hall close to your home or workplace.
