Q: Update Carrier version (bundle) without updating iOS

I have iPhone 5S A1457 with iOS 8.4.1 and Carrier 20.0. Yesterday there's LTE network started working in Belarus in band 3 (1800 MHz) - supported by my phone - but it can't register, only 2G/3G is working.

I tried my SIM card with iPhones on iOS 9.2 and Carrier 23.0 - everything is OK. How to force update Carrier bundle without updating the entire operating system? I tried to connect device to PC and open iTunes but there's no prompts for update the carrier settings. Even after resetting to factory settings. Also I can't find links for *.ipcc with a latest version to update Carrier manually through iTunes.

iPhone 5s, iOS 8.4.1

Hi Xitroff,

Thanks for using the Apple Support Communities!

I understand from your question that you would like to update the carrier settings on your iPhone without updating the iPhone Operating System. The following article explains how to accomplish this if you are using an iPhone supported carrier and includes a link on how to set the carrier’s settings manually if not.
