“Wi-Fi Assist is one of many new features in iOS 9, and for most users it’s a great addition to Apple’s mobile operating system,” Jim Tanous writes for TekRevue. “But since the feature is enabled by default when you upgrade to iOS 9, it may cause headaches for some users depending on their specific data plans or application requirements.”
“But since the feature is enabled by default when you upgrade to iOS 9, it may cause headaches for some users depending on their specific data plans or application requirements,” Tanous writes. “With Wi-Fi Assist, the iPhone will detect that the user’s Wi-Fi network signal is degrading and actively switch over to the cellular connection before the complete loss of the Wi-Fi signal. This, on paper, should produce an experience that is seamless to the user and allows them to continue their active Internet use without interruption as they leave the house or office, and early user reports confirm that this is indeed the case.”
“There are at least two scenarios in which Wi-Fi Assist may be detrimental to the user experience: data usage and network-dependent apps,” Tanous writes. “While users with larger data caps may not mind, those stuck on more limited data plans probably don’t want their cellular data connection kicking in without warning in a scenario in which a Wi-Fi signal, even a poor one, is still available.”
