To Connect or Disconnect, the Choice is in Your Hands

In today's hyper-connected world, staying offline is a choice rather than a necessity, even when you're miles away from the shore.

Thanks to the advent of eSIM technology and offshore Internet providers, you can now enjoy seamless connectivity while exploring the vast expanse of the ocean.

We will walk you through everything you need to know about Internet offshore and how eSIM plans can keep you connected at sea.

Understanding eSIM Technology

‍Before we dive into the specifics of offshore Internet, let's take a moment to understand what eSIM technology is all about. eSIM, short for “embedded SIM,” is a digital SIM card embedded directly into your device's mainframe.

Unlike traditional physical SIM cards, eSIMs offer a more convenient and flexible way to stay connected, especially when traveling internationally or accessing the Internet at sea.With an eSIM, you can store multiple plans on a single device, allowing you to switch between them without having to swap out physical SIM cards.

This means you can easily access Internet offshore services without any hassle, regardless of your location or the network provider you're using.

In addition to the benefits of using eSIMs for offshore access to the Internet, they can be used as you travel to and from your offshore location as well.

If you end up spending some time in Europe or the U.S. before making your way home, you can quickly and easily switch plans on the move.

The Importance of Staying Connected Offshore

‍Now that you know what eSIM technology is, you may wonder why it's so important to stay connected while offshore.

Here are a few key reasons:

‍Safety & Emergency Communication: When you're out at sea, staying connected is not just a matter of convenience, it's also a matter of safety. In case of an emergency, having access to reliable Internet can be a lifesaver, allowing you to communicate with the Coast Guard, request assistance, or stay updated on weather conditions and alerts.

‍Work & Business: For many professionals, staying connected is essential for maintaining productivity and keeping up with work-related tasks, even when they're offshore. With a reliable offshore Internet connection, you can attend virtual meetings, respond to emails, and access critical business applications from anywhere in the world.

‍Staying in Touch with Loved Ones: Being away from family and friends for extended periods can be challenging, but with the Internet at sea, you can stay connected with your loved ones no matter where you are. From video calls and instant messaging to social media and email, you can keep in touch with the people who matter most, even when you're miles away from home.

‍Challenges of Regular Cellular Service OffshoreVenturing offshore can significantly challenge the availability of regular cellular service for a number of reasons. Primarily, cellular networks rely on land-based cell towers to transmit signals. These towers have a limited range, which typically extends no more than 10 to 15 miles offshore. Beyond this point, the strength of the cellular signal weakens drastically until it becomes unavailable, rendering standard mobile services ineffective.

Furthermore, the very nature of the sea's vast open spaces means there are no structures on which to mount cell towers that could provide coverage. Even if additional towers were built closer to the shore, their signals would not reach far into the ocean due to the curvature of the Earth, among other technical limitations. This geographic and infrastructural limitation makes it impractical and unfeasible economically to extend traditional cellular coverage far beyond coastal areas.

This is where the advantages of eSIM technology and Internet offshore providers come into play. They offer specialized solutions that bypass the limitations of conventional cellular networks, ensuring that individuals and businesses can stay connected regardless of their distance from the shore.

‍Choosing the Right eSIM Plan for Your Offshore Internet Needs

‍With so many eSIM plans and Internet offshore options available, choosing the right one for your needs can be overwhelming. Here are a few key factors to consider when making your decision:

‍Coverage Area: Make sure that the eSIM plan you choose offers coverage in the areas in which you'll be traveling. GigSky offers extensive coverage in the North Sea and the Gulf of Mexico, but it's always a good idea to check the coverage map before making a purchase.

‍Data Allowance: Consider how much data you'll need while offshore, and choose a plan that offers enough data to meet your needs. Keep in mind that some activities, such as video streaming and large file downloads, can quickly eat up your data allowance. Consider using data-maximizing techniques to get the most out of your plan.

‍Flexibility: Look for an eSIM plan that offers flexibility in terms of commitment and duration. GigSky's plans are commitment-free; you only pay for what you need without any long-term contracts or hidden fees.

‍Network Reliability: When you're offshore, network reliability is crucial. Choose an eSIM plan that is backed by a reliable network provider, such as Tampnet, to ensure that you have access to fast and stable Internet connectivity, no matter where you are.

Will my home phone number still work with an international eSIM?

Yes. Because GigSky provides you with a data-only eSIM, your phone number doesn’t change. So, you can stay logged into your usual messaging app accounts with uninterrupted access to your contacts and conversations. However, your home network provider may apply additional charges if you make or receive calls or send texts in your destination country without using internet-based apps like WhatsApp and Facebook Messenger.

How much data do I get with GigSky’s international eSIM plans?

GigSky offers a range of prepaid data plans ranging from 1GB to unlimited data. Ultimately, it’s simply a case of choosing the right plan based on your expected data usage while traveling abroad. If you need more data, you can purchase a top-up plan to extend your service at any time.  

How do I top up my international eSIM?

After turning on notifications during installation of your GigSky international data eSIM, you’ll receive alerts when you’re approaching a 0MB balance and when your plan duration is about to expire. Please note that top-ups are valid from the purchase day rather than adding days to your original digital SIM plan. For example, if your plan expires on the 15th of the month, and you buy a 7-day top-up on the 12th, your new expiration date will be the 19th (12 plus 7).

Yes! At GigSky, we’re dedicated to providing high-quality, reliable network coverage so you don't have to rely on Wi-Fi hotspots.
