Are we only charged if we use the services when connected to a cruise ship's cell tower? The cruise ship I'm on (Carnival Sunrise, previously known as the Carnival Triumph) has no data at least under the old Triumph name. I don't plan on enabling mobile data, make outgoing calls or send outbound text messages. I also have unconditional call forwarding enabled so all calls goes to voicemail immediately. As a safety precaution, I also went into my T-Mobile account and blocked all international charged roaming. If I leave airplane mode OFF (disabled), will I be charged any roaming fees if I just have my cell radio on and it's connected to the only tower available which is on the ship?
Just want to clarify how roaming works. I assume connecting to the antenna itself is not the reason for roaming fees but the actual services used.
