What’s a SIM Card?

A SIM is an acronym stands for Subscriber Identity Module. It’s small card that fits in select phones that’s basically the digital identification for the phone. You can theoretically quickly change phones by swapping out your physical SIM card.

What’s an eSIM Card?

Fast forward to eSIM cards. eSIM stands for Embedded Subscriber Identity Module.  Instead of a physical SIM card an eSIM is a logical identity for select phones. No need for a physical SIM card.

The part where the magic comes in… Some phones also allow you to have multiple eSIM cards. So you can actually have multiple phone numbers on a single phone.

If you’re an avid reader you’ll have read my Airalo review. Airalo is an an app that allows international cell phone use throughout the world via their app and e-sim cards.

GigSky is in international coverage e-sim provider.

What makes GigSky revolutionary for cruise travelers?…

Most larger cruise ships have cellular capabilities. Ships have the equivalent of their own cell phone towers that provide service to people onboard and nearby. This is separate and different from Wi-Fi.  See Wil my phone work onboard? for more on this subject

Cruise ships are considered countries when it comes to coverage from your cell phone company. If you look under international coverage at your carrier you’ll often time see cruise ship names listed in the mix.

Here’s the thing… to my knowledge no carrier provides favorable rates or packaged data deals for ANY cruise ship. Beyond that no e-sim provider (again to my knowledge) provides coverage on a cruise ship.

GigSky…. DOES offer coverage on over 200 cruise ships!  That’s along with coverage in many foreign countries.

This means you can access the internet on ships in their network as part of their reasonable e-sim data bundles! They also offer tethering so you can use purchased data on your laptop with the aid of a compatible smart phone.

A compatible phone is required.

GigSky also offers a free 100 MB plan so you can try out their services!

If you’re a light to moderate internet user when cruising a GigSky e-sim could save you a substantial amount of money compared to onboard internet. I’ll be trying this out on our next cruise. Some questions I’m going to get answered are what is the coverage like onboard and what internet speeds can we expect.

Thinking back to our first cruises communicating back home was… brutal.

We had young children and really needed to check in on a regular basis. Options were slim and expensive. Onboard calling was out of the question financially. Onboard internet was horribly slow and expensive, albeit not as bad as ship to shore calls. We did, periodically, race the clock and try to get an email through. Typically we would try to call back home from port. We’d find an internet café or a business offering international calls by the minute and give it a go.

Times have gotten a lot better. Ship internet is much, much, much better and generally reasonably priced. This makes it easier than ever to stay connected when you need to.

Onboard Cellular

Most larger cruise ships have cellular capabilities. Ships have the equivalent of their own cell phone towers that provide service to people onboard and nearby. This is separate and different from Wi-Fi.

These towers are international no matter where the ship is. If you look on your cell phone carriers website for international coverage, many times cruise ships will be listed by names and show up alongside foreign countries.

Using Cruise Line Cellular

Using cruise line cellular for voice and data can be VERY expensive. Check with your carrier to be sure, but generally, it’s super expensive to use your cell phone (via cellular) on a cruise ship.

I know of no carrier that includes cruise ships in their international plans or international day plans. Example, Verizon’s TravelPass gets you unlimited international coverage in select countries for as little as $10 per day. That’s not available for cruise ships.

Voice and Data

Because of cost, I recommend against using cruise line for voice and data. It’s just too expensive. An internet package with Wi-Fi calling is much more cost effective. SMS messages are a potential exception to this recommendation. Keep reading for more on that.

Using Texts To Communicate While Onboard

While data and voice rates on cruise ships is generally very expensive, SMS messages are generally much more economical. If you’re looking for a way to communicate while onboard, this is an option. Check with your cellular provider to see how much text messages will cost.

Use Airplane Mode

If you choose to use cruise line cellular for voice and SMS. My recommendation is to ALWAYS turn data roaming off while onboard. Or better yet, use airplane mode.

I use airplane mode while on board and turn WiFI on. This allows me to access the Internet (with a package) and not worry about getting data roaming charges.

Full Phone Functionality with Wireless Internet… WiFi Calling!

If you purchase an Internet plan you can use many of the features of your phone like web browsing, social media, video and audio calling (Facetime, Skype, Snapchat, Facebook Messenger, etc).

There are some activities that don’t work with an Internet only connection – standard voice calls and SMS messages (iMessages do work because they rely on Internet).

You can make standard voice calls and SMS work without a cellular connection by enabling WiFi Calling

With a compatible phone and an internet connection WiFi calling makes your phone think that it has a cell tower. This allows you to place voice calls and send text messages as if you had a regular tower,

I use this and it works REALLY well. I turn airplane mode on and connect to WiFi. Quality is at the mercy of the ship’s internet but in general it has worked great for me.

Again, it’s important to have data roaming turned off. I turn my phone to airplane mode, turn on and connect to WiFi and the phone activates WiFi calling.

Enabling WiFi Calling

• Make a call with Wi-Fi Calling – for iPhone via Apple
• Make calls over Wi-Fi – for Android via Google

More About WiFi Calling from Carriers

• Verizon Wireless
• AT&T
• Metro PCS
• T-Mobile
• US Cellular
• Sprint

Test WiFi Calling Before Leaving Home

One thing to note is that you should activate and test this before you leave home. At least with Verizon, we were unable to activate it with only a WiFi connection. Maybe that’s changed, but it’s best to test it ahead of time anyway.

A way to test this is to activate WiFi calling, turn on airplane mode and connect to WiFi. Try placing a regular call. If the call goes through, WiFi calling is working.

Does WiFi Calling Cost Extra?

Generally speaking WiFi calling is free or counted the same as domestic minutes. But, check with your cell phone carrier to double check availability and pricing.
