There will be WIFI onboard, it should be in most public rooms on deck 2 & 3.
Why do need WIFI on a cruise?? The object of a holiday is to "get away from it all" If you need to check mail or send messages you can always use the facilities provide.
If the charge for using the WiFi service is similar to the QE2 charge your email or Internet surfing would need to be very important to you to justify the expense.

Cost of Internet on Cunard is 5 dollars for 10 min a lot less than phone call.
