Carnival offers WiFi on all ships, but you pay for it unless you book certain cabin types
Yes, Carnival Cruise Line has WiFi on every ship in its fleet. However, it is not included in your cruise fare for most passengers. You will need to purchase an internet plan before you board or during your cruise, or you may receive it free as part of a premium cabin upgrade or loyalty program benefit.
Carnival calls its WiFi service Serenity WiFi (for basic internet) and Serenity Plus WiFi (for faster, streaming-capable speeds). The company also offers a plan called Voom WiFi on newer ships, which is their fastest option. Which plan you can buy depends on which ship you are sailing on and when you book.
Key Takeaways
- Carnival WiFi is not free for most passengers—you must buy a plan unless your cabin type or loyalty status includes it.
- Serenity WiFi is the slowest and cheapest option; Serenity Plus is faster and allows streaming; Voom is the fastest but only available on select newer ships.
- Buying a plan before you cruise is cheaper than buying onboard, and plans can cover multiple devices depending on which tier you choose.
- Some suites and higher-tier loyalty members receive WiFi at no extra cost, so check your booking confirmation and loyalty account before purchasing.
WiFi plan types and what each one covers
Carnival offers three main WiFi tiers. Serenity WiFi is the entry-level plan and covers one device at a time. It is adequate for email, messaging, and light web browsing, but will not support video streaming or video calls. Serenity Plus WiFi covers up to four devices at once and has faster speeds designed to handle streaming video, though performance can vary depending on how many passengers are online at the same time. Voom WiFi is available only on Carnival's newer ships (Mardi Gras, Carnival Celebration, and Carnival Jubilee) and is their fastest option, covering multiple devices and supporting HD streaming.
Carnival also sells a Social Media plan on some ships, which is cheaper than Serenity but only allows access to specific apps like Facebook, Instagram, Twitter, and WhatsApp. This plan does not cover general web browsing or email.
How much WiFi costs and when to buy it
Pricing varies depending on how long your cruise is and when you purchase. A 7-day Serenity Plus plan typically costs between $60 and $80 if you buy it before your cruise, and more if you wait until you are onboard. A 7-day Serenity plan is usually cheaper, around $50 to $70 pre-purchase. Voom WiFi on newer ships costs more—often $80 to $100 for a 7-day cruise. Carnival frequently runs promotions, especially during booking season, so prices may be lower at certain times of year.
Buying your plan before you cruise is almost always cheaper than buying it at the internet desk onboard. You can purchase plans through Carnival's website, through your cruise booking portal, or by calling Carnival directly. If you decide you need WiFi after you board, you can buy it at the internet desk or through your cabin television, but expect to pay a premium for the convenience.
Who gets WiFi free with their cabin or loyalty status
Certain cabin categories include WiFi at no extra charge. Suite guests (typically cabins labeled as suites or higher) receive complimentary WiFi as part of their booking. The tier of WiFi included depends on the suite level—higher suites may receive Serenity Plus or Voom, while lower suites may receive Serenity.
Carnival loyalty program members at higher tiers may also receive free WiFi. Loyalty benefits change periodically, so check your account on Carnival's website or call their loyalty line to confirm what your current status includes. If you are a frequent Carnival cruiser, the savings from free WiFi alone can make upgrading your loyalty tier worthwhile.
How to buy WiFi before your cruise
The easiest way to purchase WiFi is through Carnival's website before you sail. Log into your cruise booking, go to the "Onboard Purchases" or "Pre-Purchase" section, and select your WiFi plan. You will see the available options for your specific ship and sailing date. Complete the purchase and the plan will be activated when you board.
You can also call Carnival Cruise Line directly at 1-800-CARNIVAL (1-800-227-6482) and ask to add a WiFi plan to your reservation. Have your booking reference number ready. If you prefer to wait, you can purchase at the internet desk on the ship, but this option is more expensive and may have limited availability during busy times.
What to expect from WiFi speed and reliability at sea
Cruise ship WiFi works through satellite connections, which means speeds are slower and less stable than what you have at home. Even the fastest Voom WiFi will not match your home internet. Expect delays when uploading photos, and video calls may freeze or drop. Streaming video is possible on Serenity Plus and Voom plans, but quality may be lower than you are used to, especially during peak hours when many passengers are online.
WiFi signal strength varies by location on the ship. Decks near the center and upper levels typically have better coverage than lower decks or areas far from the WiFi antennas. If you are having trouble connecting, move to a different area of the ship or contact the internet desk for help. They can troubleshoot connection problems and sometimes offer temporary fixes or credits if service is poor.
Alternatives if you do not want to buy WiFi
If you prefer not to purchase a plan, you have a few options. Many Carnival ships have free WiFi hotspots in public areas like the main dining room, buffet, and some lounges. These are limited and often slow, but they work for checking email or messages if you do not mind waiting. You can also use your mobile phone's cellular connection if your carrier offers international roaming, though this can be expensive depending on your plan.
Some passengers straightforward disconnect for the duration of their cruise and do not use internet at all. If you are only sailing for a few days and do not need to stay in constant contact, this may be the most cost-effective choice. If you do need to stay reachable, buying a plan before you cruise is cheaper than paying roaming charges or buying onboard.
Frequently Asked Questions
Can I share one WiFi plan with my travel group?
It depends on which plan you buy. Serenity Plus and Voom cover multiple devices, so you can share the connection with others in your cabin or nearby. Serenity covers only one device at a time, so you cannot share it. If you are traveling with a group in separate cabins, each cabin will need its own plan unless some of you have free WiFi included with your suite or loyalty status.
What happens if I buy WiFi and the ship has poor connection?
Contact the internet desk and explain the problem. Carnival sometimes offers service credits or partial refunds if connection is consistently poor during your cruise. Do not expect a full refund, but the staff can document the issue and may credit your account for future use.
Can I buy WiFi for just one day instead of the whole cruise?
Carnival does not typically offer single-day WiFi plans. You must purchase for the full length of your cruise. However, if you only need internet for a short time, the free hotspots in public areas may be sufficient, or you can buy a plan and use it only when you need it.
Is Voom WiFi worth the extra cost?
Voom is faster and more reliable than Serenity Plus, so if you plan to stream video, join video calls, or upload large files, it is worth the extra money. If you only need email and light browsing, Serenity Plus is usually sufficient and costs less.
Do I need to set up my WiFi plan when I board?
No. If you purchased before your cruise, the plan is automatically activated when you board and connect to the ship's network. Your cabin number and booking reference are linked to the plan. straightforward select the Carnival WiFi network on your device and you should be connected without needing to enter a password or visit the internet desk.
