When getting ready for an epic dive trip, we often focus on choosing the destination, checking our kit is serviced and making travel logistics but we often overlook a travel essential that’s becoming just as important, an eSIM.
Whether you’re heading to the reefs of Indonesia, exploring the iconic Red Sea, or trying to catch a glimpse of some megafauna in the Galapagos, having reliable mobile data can make your trip smoother, safer, and more enjoyable.
What is an eSIM?
An eSIM (embedded SIM) is a digital SIM that allows you to activate a mobile data plan without inserting a physical SIM card. Instead of searching for a local SIM card when you arrive, you simply download an eSIM before you travel and connect as soon as your plane lands.
Most smartphones, including recent iPhone, Google Pixel, and Samsung Galaxy models, support eSIMs.
eSIMs Vs International Roaming
While international roaming is convenient because you can use your existing mobile plan abroad, it can also be one of the most expensive ways to stay connected. Depending on your provider and destination, roaming charges can quickly add up, particularly if you’re using maps, uploading photos, or making video calls. Although many mobile networks now offer travel passes, these often have daily fees or data limits.
An eSIM provides a more flexible and often more affordable alternative. You can choose a data plan that suits the length of your trip and your destination, often at a fraction of the cost of standard roaming. Because you purchase the plan before you travel, you’ll also know exactly what you’re paying, helping you avoid unexpected charges when you return home. For divers spending a week or more overseas, this can result in significant savings while providing reliable mobile data throughout the trip.
eSims Vs Local Sim Cards
Buying a local SIM card has long been a popular way to save money when travelling, but it isn’t always the most convenient option. Finding a reputable mobile provider after arriving, navigating language barriers, presenting identification where required, and swapping out your existing SIM card can all take time. There’s also the risk of misplacing your home SIM card while you’re away.
An eSIM removes much of this hassle. You can purchase and install your data plan before you leave home, allowing you to connect almost immediately after landing. Many phones also support dual SIM functionality, meaning you can continue using your regular phone number for calls and texts while your eSIM handles mobile data. For most travellers an eSIM offers the perfect balance of convenience, flexibility, and value.
Airalo
There are plenty of eSIM providers available, but for our dive trips, we recommend Airalo because it’s simple to set up and offers coverage in over 200 countries.
One of the biggest advantages is that you can purchase and install your eSIM before you travel. Your data plan won’t start until you activate it when you arrive at your destination, so you can get everything ready from the comfort of home without worrying about using your data before your trip begins. Even if you’ve already installed the eSIM, it won’t connect until you’re in a country covered by your chosen plan.
Everything is managed through the Airalo app, making the process quick and straightforward. Once you’ve downloaded the app, you simply choose your destination, purchase a data plan, follow the installation instructions, and activate your eSIM when you’re ready to use it. Airalo also provides clear, step-by-step setup guides within the app, making it easy even if it’s your first time using an eSIM.
If your trip includes multiple destinations, Airalo also offers regional and global eSIM plans. These can be a great option for travellers visiting several countries on the same holiday, as you won’t need to purchase a separate eSIM every time you cross a border.
