eSIM technology enables mobile devices to access cellular networks without the need for a physical SIM card, making it ideal for travellers and digital nomads who need to switch networks when travelling or require better coverage.

Apple, Samsung and Google all use eSIMs in their latest smartphones - great news for those looking to switch networks and get better deals on data plans.

Apple

Apple has spearheaded an industry-wide transition to eSIM technology since 2018, with iPhones & iPads among the first devices to implement it.

eSIMs offer the advantage of being stored within your device itself, unlike traditional SIM cards, where they contain all pertinent information about your number and data plan. This makes it possible to switch plans or networks without physically swapping over your SIM card.

This innovation is groundbreaking, as it makes switching your carrier and plans a breeze. Many eSIM-compatible carriers allow for remote wiping of your eSIM and reprograming if you wish to change providers - meaning no worries about losing all your information when making changes.

This technology also means eSIMs can now be used in wearable devices like fitness trackers and glasses, marking an enormous advancement for the world of connected devices as it will enable even more apps and gadgets to have cellular connectivity.

Samsung

Samsung eSIMs are mobile SIMs built-into a device, allowing you to access data plans without the need to insert an actual SIM card. This makes eSIMs particularly helpful for travelers as they work across multiple networks and countries.

Samsung phones with this technology include the Galaxy S series and Note models. If you're considering purchasing one of these handsets, here are a few things to consider before making your purchase.

If you want to make a call from your Samsung phone, the first step is downloading the official app called Samsung Phone. This will allow you to receive calls and see who's calling you as well as access all of your contacts in one place.

Huawei

An eSIM is different than traditional SIM cards in that it's embedded into your phone and acts as a virtual SIM card, eliminating the need to exchange physical SIMs when switching plans or traveling abroad.

Huawei is the first Chinese mobile manufacturer to implement eSIM technology on some models in their 40 series, including the P40 and Mate 40 Pro.

Setting up an eSIM is as easy as scanning a QR code or entering some information manually. Thanks to this technology, you don't have to worry about losing or damaging your physical SIM card; it can be activated remotely via remote access.

Oppo

OPPO is one of China's leading smartphone brands, renowned for creating phones with impressive features at an affordable price point. The company targets young adults around the globe with their products, striving to become a brand people enjoy using.

Oppo's phones stand out among other smartphones by running Android with a custom OS skin on top. While this may be advantageous for users looking to maximize their phone's capabilities, it does mean there can be occasional bugs and issues with certain software features.

OPPO always keeps its finger on the pulse of technology, which is why its flagship models boast superfast 5G speeds and impressive battery life. Furthermore, some of their flagship models even come equipped with fingerprint sensors built-in to their displays for an effortless unlocking experience.

LG

eSIM (Electronic SIM Card) is an electronic SIM that was introduced in 2017 and will soon become widely used across most devices. It allows devices to access cellular networks without a physical SIM card, reducing the risk of data loss from devices and making it more secure for users.

Leading smartphone makers, such as Apple, are moving away from removable SIM cards in favor of eSIM technology in future models. This will simplify deployment across a wide range of mobile devices for companies and make it faster for IT teams to add new handsets to their corporate networks.

Getting an eSIM on a smartphone is easy even for those without technical skills. Select your plan, and within seconds your telecom operator sends a QR code that replaces the old SIM.
