For those who rely on internet access at every stage of their journey, eSIMs are a lifesaver—but can they keep you connected while soaring through the skies? That’s where things get tricky.
In-Flight Connectivity: Current Options Available
The ability to stay connected while flying has come a long way since the days of politely asking your seatmate for a newspaper. Now, airlines offer various in-flight connectivity options—but let’s be honest, most of them feel like you’re paying premium prices for Wi-Fi that struggles to load a simple email.
So, before we explore whether eSIMs can be the hero we need, let’s first understand the current ways airlines keep passengers connected.
How Do Airlines Provide Internet Connectivity During Flights?
Ever wondered how you're able to send a WhatsApp message mid-flight (after paying way too much for the privilege)? Airlines use two main types of in-flight internet technology:
🛰 Satellite-Based Connectivity (Most Common)
- Uses satellites orbiting Earth to provide internet access.
- Works over oceans and remote areas.
- Providers: Viasat, Inmarsat, Intelsat, Panasonic Avionics.
📡 Air-to-Ground (ATG) Connectivity
- Connects to cell towers on the ground, similar to how your phone works.
- Limited to flights over land.
- Providers: Gogo (popular in North America).
The quality of in-flight internet depends on the airline, route, and service provider. Some airlines offer fast speeds that allow Netflix streaming (hello, Emirates and JetBlue), while others feel like they’re powered by a hamster on a wheel.
Limitations of In-Flight Wi-Fi Services
While the idea of having full internet access on a plane sounds fantastic, the reality is often frustrating. Here’s why:
❌ Expensive Plans: Some airlines charge $20+ for a few hours of internet—which is more than some travelers pay for their entire month of mobile data.
❌ Slow Speeds: Even if you fork out the cash, good luck loading anything beyond basic browsing. Many in-flight networks struggle with video streaming and large file downloads.
❌ Limited Coverage: Internet may cut out over certain regions, oceans, or during altitude changes.
❌ Device Restrictions: Some airlines limit the number of devices you can connect per purchase (because why wouldn’t they make things more complicated?).
For travelers who rely on a stable internet connection, in-flight Wi-Fi often falls short. So, could eSIMs be the solution? Let’s find out.
If you're planning a trip across multiple European countries, a dedicated Europe SIM card can help you stay connected without incurring high roaming charges.
Do Airlines Offer eSIM Plans for In-Flight Connectivity?
Now, let’s get to the big question: Can you use an eSIM for in-flight internet?
The short answer? Not yet.
The long answer? It’s complicated.
While eSIMs are a revolutionary way to stay connected before and after your flight, they currently do not replace in-flight Wi-Fi. Why? Because eSIMs still rely on mobile networks, and the moment your plane reaches cruising altitude, you’re far beyond the reach of traditional cell towers.
However, some airlines are exploring new connectivity solutions, and the future of eSIM-powered in-flight internet might not be as far away as you think.
Are eSIMs Supported by Airline Networks?
eSIMs connect to terrestrial mobile networks, meaning they require ground-based cell towers. The moment a plane is above 10,000 feet, that connection disappears—leaving eSIM users without service.
In contrast, in-flight Wi-Fi services rely on satellite or air-to-ground networks, which operate independently from standard mobile providers. Since eSIMs do not currently support satellite networks, they cannot function for in-flight connectivity like traditional Wi-Fi services.
🚨 But here’s the twist: Some airlines and tech providers are exploring ways to integrate mobile networks into their in-flight internet—which could change the game for eSIM users in the future.
