My iphone4s can receive messages, but why can t I send messages?

iPhone can't send text messages troubleshooting:

1.Make sure the signal is OK and turn off airplane mode.

2.Check if the SIM card status is normal.

3.Check whether the send button is displayed in a bright color and is clickable.

4.If you can't click Send after entering text, the "Send" button is still gray and cannot be clicked. Please make a request in the settings of SMS to turn off "Show Subject Bar".

5.If you're texting multiple people and you enter numbers manually, make sure you're separating each number by pressing line breaks instead of spaces.

6.If you can receive and send SMS, after the above problems are eliminated, you can use the internal command to SMS center number:

Set the SMS center number: Dial *5005*7672*+86 SMS center number from your iPhone

Delete SMS Center Number: Call from your iPhone

Check the SMS center number set up: Dial* from your iPhone

When using the internal command, use the delete command first to set the SMS center number.

SMS** changed and changed back.

It's so easy to do! It's better to buy an i5.

Alas, I'll tell you!

1.**In arrears, you need to top up!

2.If it is mobile, call 10086, China Unicom 10010, China Telecom 10000, and then call customer service and ask her to tell you how to change the number of the SMS center and how to set it! Once you're set up, you're good to go!

3.To the after-sales replacement card, this refers to the small card! Mobile to the mobile business hall, China Unicom, China Telecom to their business hall!

These are specially handled small cards for iPhone! And it's free! It is easy to damage the chip by cutting the card yourself, resulting in the inability to send text messages!

If you don't have a small card, cut a new card! It should be fine.

4.Change the ** card suitable for the mobile phone frequency band, for example, WCDMA can only use Unicom 3G or Mobile Unicom 2G, CDMA2000 can only use telecom cards.

5.There are only four possibilities above.

Mine too, hit the mobile settings, it's still useless, it was okay before, and then it suddenly didn't work.

**I can call and receive it, and I can receive text messages, but I can't send it.

If you can't send a text message, check the network settings.

You see if the cellular data is turned off, this problem often occurs in 4s.

1. Open your phone's settings and tap Notification Center;

2. In the notification center, click Messages;

3. After entering the message, it will be displayed off on the lock screen, and it can be set to not display.

In settings, I enter notification center, SMS and turn off the bottom display in the lock screen.

Next 360 bar··· Setting a privacy number or blacklist in 360 will not be displayed directly...

Check your SMS settings.
