What should I do if I put the mobile M-Zone card into my iphone and can't send a text message, but I can receive it?

Usually a card. Try changing a card first. If you can issue other cards, it proves that your mobile phone card has problems. Many of them are problems with your own mobile phone card. You can call 10086 to ask. Most of them are card problems. If changing the card still doesn't work, I personally suggest you try formatting your mobile phone.
