Every cruise ship Wi-Fi system routes guests through a captive portal — the login/payment page that appears when you first connect. Almost all of them use your device's MAC address to track your session identity, enforce complimentary browsing windows, and log which device has already used a free trial. Change the MAC address, and the portal sees you as a brand-new device with zero session history.

Step-by-Step: Reset Your Session with MacSpoof
Download MacSpoof before you board
Install MacSpoof on your Mac at home or at the port. Once you're at sea, the only internet you have is the ship's.
Connect to the ship's Wi-Fi as normal
Join the cruise line's network. Use any complimentary time or free trial you're given.
When your session expires, open MacSpoof
Click Randomize to generate a new MAC address, then click Spoof.
Reconnect to the ship's Wi-Fi network
Rejoin the same network. The captive portal will greet you as a new, unrecognised device.
Click through the landing page
Accept any terms or tap "Get started" on the portal page. Your new session begins immediately.
Repeat as needed
MacSpoof Pro removes the two-rotation-per-day limit for unlimited resets throughout your voyage.

Download MacSpoof FreeFrequently Asked Questions
Does this work on Carnival's HUB app messaging?
The HUB app messaging uses the ship's local intranet, which is free and separate from internet access. Changing your MAC address affects internet portal sessions, not the HUB app's local messaging — those are already free regardless.
Royal Caribbean's Voom requires a login — will changing MAC still work?
For complimentary browse credits and free trial periods, yes — these are granted at the portal level by MAC. For purchased Voom packages that require an email/password login, changing your MAC alone won't help since the session is tied to your account credentials.
Will ship staff be able to tell I changed my MAC address?
No. From the ship's perspective you are simply a new device connecting to Wi-Fi for the first time. There is nothing unusual or flagged about connecting with a new MAC address.
How many times can I reset my session?
MacSpoof Free allows two MAC rotations per day. MacSpoof Pro and Lifetime remove this limit entirely, giving you unlimited resets — useful on a 7+ night voyage.
