Booking Details - My Guests (Telephone #)

We have two cruises booked on CCL. The first in 2-3 weeks has our correct cell numbers under Manage booking/ details/ My guests. The second one, which is about 75 days out, has 555-555-5555 listed for both our cell numbers. The check in information has the cell numbers correct. Is this something that gets updated as we get closer? Anything we should be concerned about?

the phone number is not needed at all. it is only needed if carnival needs to notify you if something happens to the ship like if it is arriving late

on the my guest page, you can click on Modify link and change the phone number. If there is no Modify link, then you might have to call Carnival or your TA to change it
