Hi, aziztarin.
Thank you for visiting Apple Support Communities.
I understand that you are unable to update your iOS device via the over-the-air option. At this time, this option requires the device to be connected to power and a Wi-Fi source. Here is some information regarding this option and alternatives if Wi-Fi is unavailable.
Update the iOS software on your iPhone, iPad, and iPod touch
