The mobile phone suddenly can't connect to the internet, and texting can't go out! Who is the master?

Shut down and restart, the fault is still the same, pull out the card to wipe, plug in the power supply and restart. If it doesn't work, change the card to someone else's mobile phone. If you can connect to the internet, the card is fine. It's your mobile phone. If the fault still explains the card, call customer service to check the phone bill. If there is a phone bill, the card is broken. Change the card.
