3G on iPhone 12

I have just bought the iPhone 12 in the UK and and am very annoyed that there seems no way to switch the phone to use 3G data networks. 5g is limited here, 4g is very unreliable and when supposedly connected to 4g i often don’t get a data connection. I would like the option to use 3g if I want as otherwise my very expensive new phone is completely useless..! We have vast parts of the country where only 3G is available and the phone won’t contact to the network. How have apple completely overlooked this issue? Can Apple please fix this in the next software update? I can’t be the only person with this issue - I make me want to revert to my iPhone X...!!

iPhone 12, iOS 14

That is a useless and unhelpful answer. I have a 3G/4g/5g SIM. It is exactly the same SIM I had before I bought the iPhone 12 and it worked on 3g just fine. This is a software issue, not a SIM of hardware issue. There isn’t an option to use 3g at all in iOS 14.1 on iPhone 12. That is the issue. There are a number of similar threads on other forums. https://forums.macrumors.com/threads/iphone-12-pro-and-3g.2262908/

Obviously these are not identical models. On each one go to Settings > General > About > Carrier Settings and post those picture.

In Bulgaria, there is three carriers, and the only one that does not support 5G is Telenor

Maybe that’s just one carrier, it will be better for us to know which carrier you’re using, A1 or Vivacom

@deggie I would have to agree on that, The settings are provided by the carrier, not Apple, it’s up to the carrier to decide on which technologies to be used on the iPhone.

Apple has no way of changing the carrier profile settings without the carriers knowledge. maybe a1 has better 4G/5G coverage

There are some users in this thread whose minds are made up. There’s little point in confusing them with facts.

So if you believe that it is far past time for you to sell your iPhone and buy a different one that meets your needs.

Your phone will automatically switch to 3G if 4G and 5G isn’t available, it’s just that people are complaining about wanting to manually force the radio to use 3G
