using a cell phone on a cruise

These days, staying in touch with friends and family stuck on land -- and even fellow passengers at sea -- is easier than ever. Ships now have branded apps that allow cruisers to chat with each other onboard, super-fast high-bandwidth Wi-Fi and even tablets for use at sea. Whether you want to post selfies to Facebook or check out your ship's dinner menus on your iPhone, you'll likely be covered.

Internet speeds can vary significantly from line to line and ship to ship, depending on factors such as location and available bandwidth. Most cruise lines don't offer speeds that can support streaming services like Netflix or Spotify. Royal Caribbean, however, is changing the at-sea connectivity game with a relatively affordable high-speed service that can support video and music streaming.

Just like connection speeds at sea, internet charges vary by cruise line. Some lines charge by the minute, and others offer daily or voyage-long packages. A few lines charge by bandwidth. Plus, a lot of major cruise lines are beginning to offer tiered usage packages that are priced based on the types of sites and online services passengers use. For example, Royal Caribbean has one package for those who just want to browse the web or send emails and another more expensive package for passengers intending to stream shows and movies. Carnival Corp., too, is improving the internet on all 10 of its lines and has introduced tiered usage packages. River cruise lines typically offer free internet.

Mobile phone rates at sea vary by wireless company, but they will generally reflect international roaming rates, which can be breathtakingly pricey. When the ship reaches port, pricing will switch to the country-specific roaming rate -- also not cheap unless you've signed up for an international calling plan.

Below is a rundown of what the major cruise lines offer for internet and phone service.

For some background and tips, here's everything you need to know about internet at sea.
