WiFi Assist on iPhone 4S

The setting is in Settings > Cellular and then scroll all of the way to the bottom where it should be found below the list of "Use Cellular Data For" and above "Reset Statistics"

I looked there. Under all the apps there is system services, Uninstaller apps and then reset statistics but no wifi assist. That is what is confusing....everyone saying to turn it off with ios9 upgrade but mine doesn't show up to do that.

It is not available on the iPhone 4S. That's why you don't see it.

Huh. OK that's good then I guess since it means I'm not going crazy. I wonder why it doesn't show up on my husband's iPhone5s though.

It should show up. I have an iPhone 5S and I have it at the very bottom of the Celluliar settings just like FoxFifth described.

No amount of resetting or reinstall is going to help.

Apple has intentionally removed WiFi Assist option from iPhone 4s: http://ios9news.net/no-wifi-assist-iphone-4s/

Reason? Unknown! 😕

If I were to hazard a guess, I'd suggest it's because 4S doesn't support LTE, and technically the "4G" it connects to is really a re-branded 3G (HSPA+).

marketing. yay.

in other words it's likely that having this feature on a 4S would degrade performance in some way or another. the real high speed showed up with the 5.

but this is conjecture. the guess of why, not the 4S capability and the 4G/3G network marketing. that's real 😝

double post. sorry.

We may not have the ability to turn it off, doesn't mean it isn't there sucking up data plan. The wifi range on my 4s went down dramatically, if I leave the room where the wifi router is, it pops over to 3G. Didn't do that before ios9. My ipad hasn't changed, it is wifi only.
