Why can't the mobile phone receive short messages normally after arriving in Wuhan?

Is the mobile phone number Unicom, Mobile or Telecom? Is the signal good where you are? Can I call the Internet normally? Did one person's short message not be received or did all the short messages not be received normally? Is the mobile phone in arrears? Have you tried turning the machine on and off? Do friends and neighbors use it normally? Try changing your phone and card. Call customer service, or go to the business hall to test the mobile phone card, or go to the after-sales test of the mobile phone//
