Will I incur roaming charges when making an onboard or off-ship call?
To avoid roaming charges in general:
• Place your device on airplane mode to avoid roaming charges.
• Turn on your device’s Wi-Fi connection and find the wifi network "NCL_Internet_[SHIPNAME]"
• Select the network.
• That’s it, Done.
Note: No password is required to connect to the ships Wi-Fi.
