What is eSIM?

ESIM (Embedded Subscriber Identity Module) is a virtual SIM card. It is not supposed to have a physical carrier, and it does not need to be inserted into your phone. It is enough to buy and configure it in the appropriate menu on your smartphone. 

Digital SIMs are especially convenient for travelers, as they can help them to avoid spending a lot of money on roaming plans. Before getting an electronic sim card, you should also consider some important points:

  • The electronic sim technology appeared only a few years ago, and not all phones support it. Before purchasing an eSIM, be sure to check that your model has electronic SIM support.
  • Even if your phone supports eSIM, make sure that the special slot for eSIM on your phone is free! As a rule, if you use a physical SIM card for your home operator, then you will also have a free sim slot.
  • You can buy eSIM for travelers in advance, and activate it later (before traveling).

Benefits of eSIM

An electronic SIM for travelers may be required in a situation where your home operator does not provide the possibility of using the Internet abroad or its cost is high. Sometimes you just don’t want to spend your precious time abroad on buying a local SIM card. 

A digital SIM will salvage you if your smartphone does not support the installation of a second physical SIM card (but supports a second SIM) and it is important for you that your home SIM card remains in your phone during the trip.

What is more, there are also some other significant advantages:

  • The cost of the Internet when using eSIM for travelers is often much cheaper than when using the Internet from your home operator with special options connected.
  • Your main SIM card may remain on your phone, you will still be able to receive SMS messages, and even make and receive calls, if necessary, but you will be able to use eSIM for the Internet.

How Does eSIM work?

An eSIM is a digital SIM that allows you to activate a cellular plan from your carrier without having to use a physical SIM card. Here’s a basic overview of how it works:

  1. Activation: The eSIM is activated by your mobile network provider. This can be done by scanning a QR code, downloading a carrier app, or manually entering activation details.
  2. Authentication: Once activated, the eSIM is authenticated by the carrier’s network. This process is similar to how a physical SIM card works.
  3. Usage: After authentication, the eSIM can be used just like a regular SIM card. It can store multiple profiles and switch between them, which is useful for people who travel frequently or have multiple mobile numbers.
  4. Switching Networks: If you want to switch networks, you don’t need to physically replace the SIM card. Instead, you can simply download a new eSIM profile from your new carrier.

Getting eSIMs

There are several services and different useful sim card apps that allow you to purchase a SIM card online for travel. Let’s explore some of the most useful ones.
