Apple 4s can't send SMS and MMS. What's the matter, mobile card?

Apple 4s can't send SMS and MMS, which may be caused by incorrect network settings. The solution is as follows:

1. Select "Settings" to enter the setting interface.

2. After entering the setting interface, select General.

3. Select "Network" from the general menu.

4. Enable "Cellular Data" in the network menu.

5. Find the MMS project and fill in all the data of MMS.

Format:

APN: cmnet

User name:

Password:

APN:cmwap

User name:

Password:

MMSC: Monternet

MMS agent: 10.0.0. 172

Maximum information capacity of MMS: 102400.

6. Step 6, complete the setting of MMS. Then restart the phone.

There are two ways:

One is to use the flight mode, click the switch once, wait for a moment, and then click the switch again after the functions such as mobile phone, SMS and network are turned off to turn off the flight mode. This completes the soft start of the program. The advantage of this is that an imperfect jailbreak machine does not have to restart the whole mobile phone.

The other is to click the power switch of the mobile phone, turn it off and then turn it on. Depends on which one you like.

7. After restarting, it is still being set. Pull it to the bottom and you will see the SMS option. After entering, find the MMS switch and turn it on.

8. If not, you need to call the mobile customer service number 10086.
