Network/Wi-Fi Problem

Sometimes, the activation issues might be caused by network connection. If we use cellular data connection, try turning on Wi-Fi connection instead by scrolling down to check the Wi-Fi button or go to "Settings" > "Wi-Fi" to enable the Wi-Fi toggle and choose the network.

Note: If the Wi-Fi connection doesn't change a thing, try connecting to iTunes.
