Question:

Why does my device fail to connect to the data network during the initial setup, and what can I do to resolve this issue?

Answer:

Depending on surrounding environment and network conditions, data network connection may not be established directly during the initial setup.

If booting is completed after skipping some steps , please activate a SIM card once via SIM card manager.

Then device will connect to network properly.  

<How to activate the SIM card via SIM card manager>

From Apps screen, tap Settings > Connections > SIM card manager > Check the recognition status of your current SIM card

During the initial setup, device doesn�t connect to the data network and so I cannot sign in to Samsung or Google account
