From how it works to troubleshooting issues, here’s a guide on everything you need to know about eSIM cards when travelling!
When travelling, I always make sure to get a reliable SIM card to stay connected and share my favourite overseas moments with family and friends!
But to be honest, it was a real struggle to swap the tiny physical cards and make sure NOT to lose the original. I still remember that one time I panicked on a flight back to Singapore from Greece, thinking that I’d lost my original card for good somewhere in the Mediterranean seas 🥲 Thankfully it was just stuck somewhere deep inside my pouch.
When eSIM cards were introduced, I was super happy and excited. Unlike traditional SIMs, eSIMs are reprogrammable and embedded directly into your device. So we can switch carriers or add a secondary line with just a few taps — making our travel experience much smoother and flexible. Most importantly, our original SIM cards are 100% safe and secured in our devices!
If you’re still living in the past and eSIM cards are a new concept to you, here’s our ultimate guide to everything you need to know. Trust me, it’s a life-changer.
What is an eSIM?

An eSIM is basically the digital version of a SIM card. Physical SIM cards are removable chips that connect your device to a network, but an eSIM is built directly into your devices, such as smartphones, tablets, and smartwatches.
It allows users to activate a data plan without a physical SIM card and can simultaneously support multiple network operators or phone numbers.
Another key difference between an eSIM and a traditional SIM card is that the former is reprogrammable remotely via software. So you don’t need to manually swap SIM cards when changing carriers or plans!
Benefits of using eSIMs
One of the main advantages of using an eSIM is the convenience! Previously, activating a new plan or switching between carriers was time-consuming. With eSIMs, the process is much more efficient as you can manage everything digitally without handling physical SIM cards.
For example, if you’re travelling to Japan for a week, you can easily purchase a short-term eSIM plan for your iPhone. Thus avoiding high roaming charges and saving money — perhaps for an extra bottle of sake? 😉
eSIMs also support multiple network connections or phone numbers, which you can flexibly manage on one device. Another benefit for users is the design. With eSIMs, there’s no need for a SIM card slot — manufacturers can save space and create slimmer, more compact devices.
Regarding cybersecurity, a digital SIM embedded in your device lowers the risk of SIM card theft or unauthorised use. Not to mention, there are zero chances of it getting lost.
Furthermore, it contributes to environmental sustainability by reducing electronic waste. Although it may seem like a small piece of plastic, it’s still waste that can be avoided and every bit counts!
How do eSIMs Work?
An eSIM works through a built-in chip and preinstalled software on your device. It’s pretty similar to a traditional SIM card: connecting you to a network, enabling calls, and providing mobile data.
To get started, check if your phone supports eSIM technology and review available data plans for your travel destination online. Next, download the service provider’s app and follow the setup directions. eSIMs are programmed remotely, so you can switch carriers or data plans by scanning a QR code or choosing options from a menu.

When deciding on an eSIM plan, consider where you’re going and how much data you’ll need. Coverage varies among eSIMs, so choose one that supports your destination. If you’re planning a longer stay, select a plan that fits your duration. And don’t worry, many service providers allow you to adjust your plan as needed.
In addition, consider your usual data usage: 1GB might be enough for emails and Google Maps, but you’ll definitely need more for streaming Netflix and uploading IG stories during your travels!
Most importantly, choose a reliable provider with good support, like Saily. It’s trusted by 14 million users and backed by Nord Security (the company behind NordVPN), so security isn’t an issue.
Plus, this fast-growing eSIM service offers plans in over 150 countries (e.g United States, Thailand, Japan, France and more) and provides 24/7 assistance 💯

Common issues and how to troubleshoot them
For those new to eSIMs or are facing issues with your current setup, knowing how to troubleshoot problems is helpful. Here are some common ones and how to fix them. But if all else fails, directly contact the relevant customer service for advice!
1) The eSIM does not show up on your device
If your eSIM doesn’t appear on your device, the reason could be improper installation, compatibility, or software issues. Ensure your device is eSIM-compatible, then double-check the installation and restart your device. Updating your device’s software might also help.
2) The eSIM activation has failed
This is usually due to an invalid or expired activation code and compatibility issues. Firstly, verify that your device supports eSIM and ensure the activation code is correct and valid. If there are still issues, contact customer support.
3) There are connection issues with the eSIM
Problems like no Internet or slow speeds can be due to poor network coverage, incorrect settings, or data plan limits. So we’d recommend checking on these issues first and then restarting your device.
4) There are some network compatibility issues
This might be due to your device or the network not being compatible with the eSIM. Do contact your carrier for support!
