Before the iPhone5 Unicom card is sent, others can receive it. Recently, I have suddenly sent short messages, but I can't get them. It's normal to receive text messages and make phone calls.

There are several reasons why the other party can't receive the text message after the mobile phone sends it:

1. Consider whether there is a problem with the other party's mobile phone, and contact the other party in other ways to ask;

2. Take out the mobile phone card and put it in another iphone to send a text message to test it to see if the other party can receive it normally. This is to eliminate the quality problems of mobile phone cards;

2. At the same time, try to put someone else's card in your mobile phone and see how to send text messages. This is to eliminate the problem of mobile phone settings.

If it is a problem with the mobile phone card, the owner can bring a valid certificate to Unicom's own business hall to change the card; If it is a phone setting problem, and the mobile phone is a Unicom contract machine, you can bring your valid certificate to the main business hall of Unicom. Generally, there will be iphone technical support personnel to check for you on the spot. If you bought the mobile phone elsewhere, you can take the receipt to the after-sales office for testing.
