The mobile phone has a phone bill but can't make calls, send text messages, receive text messages, answer the phone, check the phone bill and balance, but can't send messages.

I suggest you put the card in someone else's mobile phone to see if it can be used normally. If so, it's your phone problem, if not, it's the card problem. Call1001010086 for card problems, and call after-sales for mobile phone problems. Then analyze why your mobile phone/card can't be used.

Not being able to use your card is not necessarily a problem with your card, but it may also be caused by the communication company or a network problem. There are many external reasons why mobile phones cannot be used.
