Q: Where is switch 2G/3G/LTE in iOS 8?

Yes, I also have the same problem. my iphone 6 is ios8.1 and only open 4G why? My location is Saudi Arabia and my operator name is Mobily. Please fix the problem ...

I have same problem too. iPhone 5s (a1533) with iOS 8.1 — have not toggle to 3g/2g.

Already reset settings and clean install os — problem is staying.

Most threads that I have read stated that a carrier file update was also required. Use this support document to check your carrier file, and if you do not have one, then check with your carrier to find out when they intend to send it out. iOS: Updating your carrier settings

There are no any update settings.

I only have the 3G toggle, but I suppose it's because I have an iPhone 4S, I don't even have LTE so...

Same here... Bug?

5s 1457

That is correct. The iPhone 4S does not support LTE.

Then check with your carrier.

Check what?

I have working LTE, but I can't choose force 3G or 2G? How carrier can help?

The available network parameters are the responsibility of the carrier, and will appear based on the settings of the carrier and the carrier file. Any questions about these features must be answered by the cellular company that provides your service.

Read the link that ChrisJ4203 provided above.

The reason Android phones show this option is the carrier provided settings for the phone. And the carrier will provide settings for the iPhone if you follow the instructions or call the carrier.

Simple cellular phones as you state, do not have carrier files to handle settings like a smartphone does. The ability to make setting changes is determined by the carrier file as Lawrence and I have stated. Contact your carrier.
