Siri not working over LTE in iOS 8.4

I had the same problem… no Siri on LTE. I have iPhone 6 Plus AT&T. I tried resetting network settings, hard reset, everything. What worked for me is turning off Siri then doing a hard reset after. When the phone booted back up I didn't have to enable Siri it was already active. This work for me hope it works for you guys.

i have no mobile data at all On any of my phones . We have 4 iphones . No maps , no data unless under wifi!!! The awesome ATT REPRESENTATIVE have me directions to get home from the unfamiliar area I was in. THIS IS NOT A ATT ISSUE IT IS AN APPLE ISSUE! Their server are not connecting with the new update to anyone with Att mobile data !! How to prove this is download google chrome and magically your data works !!! Any Apple based application is not working ! Frustrating because apple is propriety and they won't admit this huge mistake !!

I talked to Apple Support twice today and they could not find a fix. They said they've seen a lot of issues as a result of this update and don't have a solution. The suggestion I received was to wait until Apple releases a fix.

I have solved this issue - At least on my iPhone 6 on AT&T.

I had an old VPN configuration that would no longer connect. Once I deleted it, Siri and Find Friends started working on LTE.

ita an apple issue with with anything mobile data related througha Att network . Apple is aware of the problem has notified Att but won't admit their mistake !

Siri now works on AT&T LTE for me (DC metro area) as of 10:50pm EST. I didn't have to do anything to get it to work.

Yes but as I said I can cut off the cellular connection and nothing changes as long as wifi is available while the device is locked. Plus my wifi only iPad picks up emails, messages, etc. while locked. All of my devices do. I can see the data usage for each device that has cellular usage and it's nil when wifi is available. Such as with Airplane Mode enabled. Either my devices have a quantum connection to the Internet while locked or they stay on wifi.

That's always been my experience.

Yes the services are now working, at least in Baltimore where I am. Nothing needed to be deleted.

BBecause it is an apple server issue!! Trust and believe I sat on the phone with the awesome att rep who was nice enough to give me ditectiosn to get home after my maps wasnt working through apple !!! They better pray they fix this problem immediately ! If my children can not contact me while at camp for an emergency I will be one angry mom let alone apple customer !!

Working in Allentown, PA area.

You are correct and bring up a good point about your WiFi-only devices still getting timely notifications (obviously they're not using cellular).

Everyone else needs to read up on WiFi beacons and how they function with iPhones. iPhones DO use WiFi when asleep—the same way that WiFi-only iPads do it. The same way that iPhones without SIM cards do it.

And if I shut down a device or cut wifi off it drops right off Airport Utility regardless if it was connected just seconds ago. Cut wifi back on and it magically reappears. Whether that proves anything I don't really care because only using available wifi when my devices are locked all the services function. Maybe there is a quantum event taking place.

Seems to be an issue with only AT&T

That's the way it has always worked for me. But you know we have a lot of neutrino emissions in Baltimore so who knows 🙂

Correct.

Your device listens to beacons from your router and only "fully" wakes up its WiFi radio and components when there's a notification. So technically, yes, it disconnects from your WiFi network but is still listening to beacons (which consumes very little power).

As a test, turn on Airplane Mode and then enable WiFi. This turns off your cellular connection but keeps WiFi on. Put the phone to sleep and it'll disconnect from your network in a few seconds (assuming you're not downloading anything). Send a text or email from another device and your phone should receive it almost immediately after receiving the beacon and waking up the WiFi radio. That's your "quantum event".
