    [Update: This issue appears to have been fixed in iOS 10.1 Beta 2 as carrier settings have been updated to Three 26.0. My iPhone 7 Plus now appears to be defaulting back to 4G when it should, as was expected and experienced on the 6S Plus - however some people still reporting issues even after this update]

    Ok,

    So I had all the past iPhones and ever since I was able to get 4G, my phone would always pick it up at least while I was at home, anywhere in the house or while at work, wherever I was in the building.

    My last phone was a 6S Plus which I had since launch and likewise, no issues whatsoever.

    My new iPhone 7 Plus however, I have only for the briestfest of moments seen it on 4G. The rest of the time, it is solidly stuck on 3G.

    Things I have tried:

    Go to settings and then "about" and waited a good 5 minutes and I can confirm I have the latest carrier settings.

    I have reset network settings, phone has rebooted and still on 3G.

    I have confirmed 4G is enabled in the settings under carrier for voice and data. I have also switched it to just data and waited - still only 3G.

    I have restored the phone and re-loaded my backup - still on 3G.

    I have restored the phone and set it up as blank/new phone - still on 3G.

    I have this morning gone to the carrier and swapped out a sim for another - still on 3G.

    *Now none of these worked*

    Anyone else with a 7/Plus having issues?

    My network here in the U.K. is "3".

    Either something weird is happening with the new phones or I guess my phone needs changing, which is weird because if its connecting to data and also to 3G - why wouldn't 4G work

    Any ideas?

    Yeah, I think I've got the same. My girlfriend is sitting here with 4G in here iPhone 6 and I've got 3G on my 7+. Hadn't actually noticed it until reading this. Both 3 UK.

    are you usually the SIM that came with your new phone? do put the old SIM card in. also make sure 4G is turned on under Cellular Data Options

    Do you know if the 4G in your area is running on the 800Mhz band?

    On the 3 UK network 3G has higher network priority than 4G 800, maybe the iphone 7 has better 3G reception than the 6S. 4G800 only appears as a last resort.

    See if there's a carrier update for your phone. I'm on Three and got one recently.

    (You're better off Googling how to do so.)

    Good shout but where I work I get full five circles of 4G - today I got 4-5 circles 3G all day. Never once switched to 4G.

    Also, on my 6S - I was easily on 10-15 Mb download but now in the 7+ and on 3G it's just 1-3 Mb....

    Already stated that I've tried carrier update and that I've confirmed im on the latest (Three 25.1)

    Thanks anyway

    Can confirm I've got the same issue here with a 7+ and Three UK!

    Hopefully either an iOS or Carrier update fixes it!

    I've just done a bit of investigation and after doing a hard reset (Power + Vol Down) it initially connected up to 3G but switched to 4G after about 30 seconds

    Ok, so it's not just me ✌️️
    --- Post Merged, Sep 18, 2016 ---
    True, I can get it to connect by doing this but then whether it's a few minutes or so, it always reverts back to, and stays on, 3G

    Carrier issue I reckon. Just contact them to ensure 4g is activated for the phone as may be because you changed phone and on their system has it only locked into your previous phone. Should not cost you anything at all except the call/online chat time.

    I had the same issue, power/volume down reset appears to have resolved it.

    Just looked now after going on break and same, back to 3G when the 6S+ would never switch from 4G !!!
    --- Post Merged, Sep 19, 2016 ---

    Was only a temporary solution for me
    --- Post Merged, Sep 19, 2016 ---
    Yeah, lasts from a few minutes to a few hours but then stuck on 3G again until I hard reset or reset network settings, even sometimes then, doesn't reconnect to 4G when it should!!

    Exactly the same experience here, reported to Three UK and they're looking into it and calling me back.

    Same issue here, I got my new 7 on Friday but only noticed today.

    Tried the power button with down volume, got 4G for now, lets see if it stays....

    Yep, same issue.

    I haven't contacted Three yet but mine loves to stay on 3G and I have to force it to use 4G by toggling 4G on and off. Doing that also sometimes kills my cellular connection altogether seemingly as although it'll show I've got maybe 4 bars of 3G, there will be no connection. Hope it's fixed soon.

    Just posted about this in the Three preorders thread. I'm having the exact same issue but using the iPhone 7 not the plus model.

    Three advised me to refresh network settings, remove the SIM card, toggle 'Data Only' under enable 4G and not to have it set as 'Voice & Data'. So far absolutely nothing has worked.

    They're calling me back on Wednesday with an update apparently.

    Still no luck with me either.

    Starting to think a carrier update will be needed to fix.

    I've literally tried every single thing you could. Nothing works ;(

    Hopefully it'll happen soon, 3G feels so slow compared to 4G. Guess I should be grateful at least I'm getting some service.
