Can't get 4g on iphone 7

I'm having a similar problem. iPhone 7 Plus, Three, and no 4G. It picks up on a restart then flips to 3G and never goes back to 4G.

I note that mine's an A1784 model which has an Intel modem, and at the moment, after four days with the phone, I'm very disappointed that it doesn't seem to work properly!

Who is your carrier? What country are you in? Where did you get the phone? What does it say in settings>general>About>Model?

Did you inform your carrier that you now have an iPhone so they could properly provision your account?

Thanks .. it worked ...

Hi

Apple has today released iOS 10.0.3.

This fixes bugs including an issue where users may lose cellular data connectivity:

Update the iOS software on your iPhone, iPad, or iPod touch - Apple Support

Same issue for me too. Fails to maintain signal on 4g unless I do a restart and I'm missing calls too as it fails to reconnect to 3G network too (despite showing full 3G reception).

I'm on Three in the U.K. with a 7Plus

I Have the exact same issue on Iphone 7.

Previously had phone 6 with the Three network in the UK.

Spent an hour in the Apple store two weeks ago where they basically made it my issue and advised to restore IOS and then set the phone up as a new device. Instead of retoring from Icloud backup. This basically wasted 2 hours and I still have the same issue. Three have been great, they have swapped the sim to see if that would sort it but Apple are no use at all..

When on 4g the speeds are shocking, and when on 3g the call quality if affected. If you disable the 4G completly the call quality improves but then you never get 4g until you re enable.

Now been 4 weeks with this issue and no further forward.

that would be good if people at apple genius bar actually admitte an issue instead of spending 2 hours of my time being wasted for an apple related issue And the. 3 weeks in from the issue it's still not resolved.

tempted to return the phone back to apple under the sale of goods act.

First you'll need to make sure 'Enable LTE is switched ON' at least for the data. You can make sure by going to Settings -> Cellular -> Cellular Data Option -> Enable LTE. Then reboot your device. If still have this issue after enabling LTE and rebooting, then you'll need to talk to your carrier.

Done and still the same issue.

Been to carrier shop In the U.K. and they have kindly swapped the sim card on 2 occasions.

Three have been faultless in this and they advise other customers are having the same issue. Apple need to fix this.

Sadly the exact same

I have been onto Apple Care Support on Wednesday for the best part of 3 hours

Exactly the same following the 10.0.3 update. The Apple escalation rep who is dealing with my case has said 10.1 should be out soon to fix the issue. Sadly this is not the answer I want to hear.

I also had a tennis match between Apple and Three both saying it was each others issue. Meanwhile I am stuck in the middle with no 4G and no one appears to know what to do.

BTW if you have a case with apple tell them to link it to my case ID ****.

I have just completed ERROR logs for the above case and going to issue these to apple.

I've spent a long time looking into this with the Three 2nd line tech support guys.

Basically, it doesn't matter too much which carrier you are on, as people are having issues on multiple carriers. iOS 10 just doesn't work well on 4G. This exacerbates itself when you have "Voice and Data" set to 4G, as the phone doesn't receive incoming calls.

The 10.0.3 fix only resolves 4G connectivity issues for iPhone 7 and 7+ on the Verizon network in the US, although the 10.1 beta is apparently much better for UK carriers and does seem to fix it.

What it comes down to is that until there is a 10.0.4 or a 10.1, you are best off making sure 4G is set only for data, and you may need to turn off 4G altogether. The best way to describe this is a very poor implementation of the 4G in iOS 10 by Apple, probably as a result of the Intel Modem they've elected to introduce, this time around.

Three's comment on this was that they are working with Apple to get the issues resolved in a new iOS release.

Just to add to the bashing Apple will get over this...

The main issue apart from the obvious 4G or lack off, is the fact both Apple and Three (an I guess other carriers) are blaming each other with the customers spending our hard earned cash stuck in the middle watching the blame Tennis rally.

I was on the phone with Apple Engineer support for almost 2 hours last week trying to get this sorted, Then was on the phone again on Saturday for a hour gathering more log files for this issue.

Your solution for disabling Voice & Data option works but by doing so my call quality drops significantly and the person on the other end of the phone struggle to hear me.

Basically as it stands it’s a very expensive screen. It’s so bad that even on 3G its taking ages to download albums and tracks via Apple Music which I pay £9.99 a month for the privilege of listening to music on my commute. In order to use it at present I need to ensure all tracks are downloaded prior to leaving the house / office.

So far the 10.1 update looks like its resolved the 4G issues. My phone did pick up 4G connectivity when I previously jumped from Wifi to Mobile Data.

Will not hold my breath just yet as the 10.0.3 update done the same and after a few hours went back to the same issue.

Also I am switching the 4G back to Voice and Data.

Im on AT&T and also can't get any 4G on my iPhone 7. I had the iPhone 6s previously and had no trouble . That stupid update they did was just for Verizon customers. I'm running the latest firmware (10.1.1) and nothin works. Have gone to AT&T stores and they replaced the sim and reset the network settings but nothing works. I paid $649 for this BS
