The Samsung Galaxy Watch5 Pro can also be used to its full extent without the LTE function as long as it is connected to a Galaxy smartphone via Bluetooth or WLAN. Here are the most important points:

- Bluetooth and WLAN connection: The watch can be connected to a Galaxy smartphone via Bluetooth for notifications, calls and other functions. A Wi-Fi connection also enables access to online services and synchronisation with the smartphone.
- Restrictions without eSIM: Without an eSIM or LTE connection, the watch cannot be used independently of a smartphone to make calls or transfer data online. All functions that require a direct Internet connection, such as using online services without the connected smartphone, are restricted.
- Offline functions: Many functions such as fitness and health monitoring, GPS route tracking and sleep tracking can also be used without an LTE connection as long as the watch has been synchronised with the smartphone beforehand.

To summarise: The Galaxy Watch5 Pro can be used without an eSIM or LTE function, but some functions that require a direct internet connection are limited.
