Apple has posted a support document, “About Wi-Fi Assist” which explains
that with iOS 9, you can use Wi-Fi Assist to automatically switch to
cellular when you have a poor Wi-Fi connection.
How Wi-Fi Assist works
With Wi-Fi Assist, you can stay connected to the Internet even if you
have a poor Wi-Fi connection. For example, if you’re using Safari with a
poor Wi-Fi connection and a webpage doesn’t load, Wi-Fi Assist will
activate and automatically switch to cellular so that the webpage
continues to load. You can use Wi-Fi Assist with most apps like Safari,
Apple Music, Mail, Maps, and more.
When Wi-Fi Assist is activated, you’ll see the cellular data icon in the
status bar on your device.
Because you’ll stay connected to the Internet over cellular when you
have a poor Wi-Fi connection, you might use more cellular data. For most
users, this should only be a small percentage higher than previous
usage. If you have questions about your data usage, learn more about
managing your cellular data or contact Apple Support.
You can use Wi-Fi Assist with any iOS device with iOS 9 or later, except
for:
• iPhone 4s
• iPad 2 Wi-Fi+Cellular
• iPad (3rd generation) Wi-Fi+Cellular
• iPad mini (1st generation) Wi-Fi+Cellular
Turn Wi-Fi Assist on or off
Wi-Fi Assist is on by default. If you don’t want your iOS device to stay
connected to the Internet when you have a poor Wi-Fi connection, you can
disable Wi-Fi Assist. Go to Settings > Cellular. Then scroll down and
tap Wi-Fi Assist.
Items of not about Wi-Fi Assist
• Wi-Fi Assist will not automatically switch to cellular if you’re data
roaming.
• Wi-Fi Assist only works when you have apps running in the foreground
and doesn’t activate with background downloading of content.
• Wi-Fi Assist doesn’t activate with some third-party apps that stream
audio or video, or download attachments, like an email app, as they
might use large amounts of data.
