Приветствую.

Как я могу обновить iOS, используя LTE подключение на iPhone 5s.

Есть-ли такая возможность?

Не имею возможности подключить данное устройство к ПК и WiFi.

"Кнопка загрузить и установить"–неактивна без подключения к WiFi.

нет. Использование Wi-Fi или MiFi или компьютера требуется

To update over the air from the phone all of these requirements must be met:

• You need at least 6 GB of free storage
• You must be connected to a Wi-Fi network (and not a personal hotspot)
• The phone must be charged to at least 50%, and preferably plugged in so it stays above 50% during the update
• The phone must not be in Low Power Mode
• The phone must not be connected through VPN
• The phone cannot be in Airplane mode, and must have a mobile network connection

If you can't meet all of them you can still update using your computer.

Wi-Fi требуется для обновления по воздуху. Если у вас нет доступа к Wi-Fi, вам придется выполнить обновление с помощью компьютера.

Wi-Fi is required to update over the air. If you don't have access to Wi-Fi you will have to update using your computer.

I see you have an iPhone 5s.

An iPhone 5S can only run as high as iOS 12.5.5

Here's a simple and fast way to see what is possible with your device, including updating it to the highest sub-version (e.g., 12.5.4 --> 12.5.5) of an iOS/iPadOS you may already have:

On your device, tap:

Settings > General > Software Update.

1. If it says your device is up to date there is nothing more you can do. If apps you are trying to use say you need a higher iOS version, you will need to buy a newer device if you want to run those apps or features.

2. If it says an update is available you will normally only be given one update selection which will be the highest available iOS version supported by your device. However, if you are running an iOS 14 version that is OS 14.5 or greater, you may see two options. Click on a link below for full instructions about how to update wirelessly, or using a computer (see links in document) if you have storage or connectivity issues. If the update listed is not equal to or higher than the iOS version you need to use a feature, you again will need to buy newer equipment if you want to use that feature.
