What is the first thing you do when you go abroad? Most likely trying to connect to a wifi network and access the internet, researching a location where you can get a physical SIM card, or communicating with someone over wifi because you don't have a sim card. But thanks to eSIM, you can get to all of them instantly. Even before you leave the country, you can have an eSIM line and start using it without any problems from the moment you arrive abroad.
How to use eSIM abroad? What is eSIM, how to install it, what are its advantages and disadvantages? All the details are in this guide.
eSIM is a digital sim, unlike the classic physical SIM cards we know. It can not be attached or removed anywhere on the phone. It is not something that we can physically access. eSIM (embedded SIM) stands for “Embedded SIM” and is a previously integrated digital sim technology already present inside the device. Thanks to a chip built into the device, it can be programmed remotely and multiple profiles can be installed.
The technological infrastructure of eSIM is quite simple and secure. Let's clarify these in 4 steps:
GSMA Standard: eSIM technology is based on GSMA (GSM Association) standards. Thanks to this, it is accepted by all mobile operators and ensures global compatibility.
Remote SIM Provisioning: eSIM allows operators to install and control profiles remotely. Users can activate eSIM via QR code, app or operator connection without going to service points.
EUICC (Embedded Universal Integrated Circuit Card): This is the technical name of eSIM. This chip allows switching and using multiple operator profiles.
Security: eSIM is more secure than physical SIM. There is no such thing as loss and theft.
For iPhone:
• Settings > Cellular > Add eSIM
If this option appears, your device supports eSIM.
For Android:
• Settings > Connections > Sim Card Manager > Add eSIM
• Settings > Network & Internet > Mobile Network > Advanced > Add Operator
If there is an eSIM related option in these menus, your device is compatible.
If you wish, you can also check it from the manufacturer's website of your phone.
You also have the opportunity to check it through the IMEI information. Type * #06 # on your phone's call screen and if the “EID” (Embedded Identity Document) number appears on the pop-up screen, your device is supported by eSIM.
After first testing whether your device is compatible with eSIM, you can request an eSIM from an eSIM provider of your choice. You can use the UPTION card for payment transactions.

Before starting the eSIM setup steps, you should make sure you are connected to a wifi network that works smoothly. Then add Phone Settings> Cellular > eSIM (may vary by device). Then scan the QR code that is usually sent to your email. After the eSIM profile is loaded, select which line will be your primary and choose which line you want to use for data, calls, messaging. You can select only data for abroad. This way you will have set up your eSIM.

You can also use dual sim if you wish. You can open eSIM only for data. You can only use your physical SIM for calls and messages without disabling it.
You may also need to turn on your data roaming depending on your plan.
The expired eSIM will automatically shut down by itself. But you can also perform this process of your own volition. Turning off or disabling eSIM is a fairly simple application. You can easily do it from the settings of your device. Let's go through the steps now:
