When installing iPhone security updates, airplane mode is turned off by Apple automaticallly triggering international roaming charge of $16.00 even roaming service is never used. Why is Apple turning off airplane mode - an issue only when travell

Apple does not turn off Airplane Mode during iPhone security updates. However, when you restart your iPhone (which happens after an update) Airplane Mode is turned off, because it must be off to activate your phone after a restart. It’s generally not a good idea to update when away from your home network, because if anything goes wrong it can leave your phone unusable.

I have this same issue but it does not happen with every update which is even more annoying. Apple should disclose if the update turns airplane mode off before we begin the update process. If they disclosed it with some sort of pop up warning, we could choose not to do the update and avoid being charged for coming out of airplane mode. AT&T has been very understanding about crediting us for the times when Apple updates take the phone out of airplane mode, but it is, in my opinion, Apple's responsibility to notify us prior to initiating an update if this will happen. The updates check to see if there is enough battery life, etc. so they have some awareness of the status of the phone. It would not be difficult for the update process to notice the phone is in airplane mode and warn the users so we could opt out of the update.
