Why can't I send a text message when my mobile phone is fine! ! ! ! ! ! ! ! ! ! ! ! !

Maybe there is something wrong with the high-frequency part of the mobile phone, or

You call 10086, and ask them to refresh the SMS function of your card.

If not, you can change the card. The card replacement fee is about several yuan. It is possible that the SIM card is damaged and there is something wrong with its function. Just change the card.

Actually, my mobile phone used to be like this. At that time, I thought there was something wrong with my mobile phone, so I bought a new mobile phone. In fact, there was something wrong with my card. Why don't you take out your card and put it on someone else's mobile phone to see if you can send text messages? If that means there is something wrong with your mobile phone, if you change your mobile phone or send a wrong message, then there is something wrong with your card friend. So it's simple. You can change a card.

I hope your question is like this

It seems that you can change the card without changing the number! (If your ID card has been issued)

I hope I can help you ~ ~
