Apple phones can receive short messages, but they can't send them. What happened?

If it's because you can't send iMessage information through the network at present, please press and hold the content of the short message to be sent, and then select the option of sending it by short message service, as shown in the figure.

When the iMessage status has been turned on, it is best to turn it on as a short message sending option in Settings-Information. In this way, when the network is not smooth, or when there is no network, it will be automatically sent by traditional SMS.

03

Also, you can set up a network to solve it. Open iPhone settings.

04

Locate the General option and open it.

05

Find the "Network" option on the General Settings page and open it.

06

Then turn on the cellular data network.

07

Open all SMS/MMS fields.

08

Then keep texting.

The third solution is to turn on the dial of the mobile phone and set the number of the SMS center. The query status is *#5005*7672#, the setting number is *5005*7672* SMS center number #, and the deletion number is ##5005*7672#.

Another possibility is that the mobile phone is in arrears, so you can't send and receive text messages, just charge the phone bill.

If the mobile phone can't send short messages, I suggest you check whether you can answer the phone. If not, please check whether the machine signal is stable and whether the phone bill is sufficient.

If the phone call is normal, but you can't send SMS, the suggestions are as follows:

1. Check whether the information center number is correct (please contact the local network operator for the information center number, and the telecom card has no information center number setting).

2. Try to replace another SIM card.

3. Check whether the machine has a firmware/system update push notification. If yes, please upgrade your phone to the latest version.

4. If it is invalid, please back up data (contacts, multimedia files, etc.). ) and restore the machine to factory settings.

After the above operations, the problem still exists. Please bring the purchase invoice, maintenance card and machine to the Apple Service Center for inspection.
