Apple's mobile phone can't receive short messages from airlines after being updated.

The reasons for not receiving SMS are as follows:

1, SMS center number is incorrect: because different regions of the country, different carrier networks, the corresponding SMS center number is also different. In addition, for users, it is not only tedious to find the number of SMS center on the Internet, but also the version and year of many materials will cause inaccurate information. I suggest you go to the local operator's business hall to find out, or call 10086.

2. Poor cell phone signal leads to network instability: If you are in an unstable situation, the network is temporarily missing, or affected by other aspects, SMS may be temporarily unavailable or delayed. To solve this problem, you need to go to a place with good signal to receive short messages.

3. It may be that you set the blacklist function of your mobile phone: this will lead to some people's short messages not being received. At this time, it is necessary to turn off the blacklist function of the mobile phone and restart the mobile phone to solve it.

Airmail SMS only reminds you that the booking was successful, and it doesn't matter if you don't receive it.

If the order is confirmed, you can get your boarding pass and board the plane at the airport with the certificate you used when booking.
