Two days ago, I set up a phone to transfer to a mobile card. As a result, I sent a text message to this mobile phone number after canceling call barring, but I couldn't get it.

Personally, I feel that your mobile phone has too much information, and then the legendary memory is full. . I used to be like this. It is ok to delete some received information. . . Maybe it's the card. Maybe the telecommunications hacked your number. I once turned off my cell phone. . . . If it's a card problem, go to a bigger telecom business hall with more service windows. . .
