Guide: How does an eSIM Works: Everything you should know
While the need for connection is primary, resources quickly move to the timeless principle – form follows function. The connectivity that SIM enables has declined in 1991 from a credit card size to a little finger miniature nano-SIM. However, we still need two SIM cards to use two different numbers on our smartphones. Not too long. The new mobile innovation called eSIM will change the way we experience and use multiple SIM cards on our smartphones. Traditional SIM cards tend to lose their function when you do phone dives into the water and is seriously damaged. Even if you have it phone along with the SIM card, getting a new one is rather tedious. It’s equally cumbersome for the mobile operators too. That’s why smartphone makers and mobile operators are teaming up to deliver a ubiquitous solution in the form of eSIM. While it holds a lot of promise and an interesting future full of convenience, let’s dive in to find out more about the eSIM.
What is eSIM
The eSIM stands for electronic Subscriber Identity Module and aims to be the virtual equivalent of the physical SIM card. You can activate and subscribe to mobile services from more than one mobile operator without having to insert a new physical SIM card into your specific device. A typical eSIM is embedded on a motherboard or printed circuit board phone or a smart device and it’s a fraction of a nano SIM card.
That is the main concern of consumers: buying a dual SIM 4G smartphone and new SIM cards. That means you can enjoy the dual or multi sim experience on a smartphone as well as change and manage it easily. Don’t we all want flagships that are powerful smartphones and protect against water and dust? Replacing the SIM card holders with eSIM is therefore a great start. In the future, smartphones, tablets, computers and other smart devices can use an eSIM to let you enjoy mobile and data services from multiple cellular providers.
How does it work
An eSIM, short for an Embedded Universal Integrated Circuit Card, comes with a Machine to Machine (M2M) installation and Remote Provisioning capabilities. In simpler terms, a smartphone or smart device manufacturer will solder it directly to the motherboard of said device. The remote delivery capabilities make the process of activating and managing the eSIM compatible devices easier. So you don’t even need one mobile shop of the operator.
Let’s say you want to use a second 4G LTE connection on an iPhone, because you don’t want to bring another phoneAll you need to do is get the subscription from the eSIM support mobile operator such as Airtel. The mobile operator shares QR code or other details with activation code along with SM-DP + (Subscription Manager Data Preparation) server address and confirmation code. Note: By default, all iPhone models use Nano-SIM as the primary SIM card, and the e-SIM card is the secondary SIM card. So when the other mobile operator activates your eSIM, then you can switch between your phone number profiles and other data services of your phone’s settings instantly. That’s so handy when you travel worldwide. Imagine taking a trip without worrying about buying a “tourist” SIM card abroad. From activation to selection of the local network, everything would be possible by simply scanning a QR code or entering the necessary data in the phone’s interface. That will help with quick switching and activation of local mobile operators while your phone is on international roaming.
eSIM compatibility with Premium devices
Fortunately, Indian telecom operators are rapidly adopting and rolling out eSIM capabilities. Apple’s premium iPhone models, including the iPhone XR, iPhone XS, and iPhone XS Max, made their debut among the first phones to provide the eSIM support. That means the iPhone owners can use the dual SIM functionality by applying a simple process and activating the eSIM.
Airtel is one of the first players in India to start eSIM activation for Apple’s iPhones. The Indian mobile operator now extends eSIM support to others phones starting with Google’s premium Pixel family, including the Pixel 3, Pixel 3 XL, Pixel 3a and Pixel 3a XL. Along with that, other mobile operators are also working on offering eSIM support for the said premium devices and more phones You can expect support for eSIM to expand to a wider range of smartphones and a wider range of devices, such as smartwatches, health bands, tablets, laptops, wearable health gadgets and more.
Smart cars powered by eSIM
While those smartphones and smart devices are in the pipeline, car enthusiasts will want to be the first to witness the connected car experience. Thanks to that, the eSIM support will power SUVs such as Hyundai’s Venue and MG Motors’ Hector in India.
With the connected cars, the eSIM will equip a range of in-vehicle services such as navigation, emergency / panic buttons, infotainment, auto health, breakdown services, telematics and even diagnostics. That makes so many things easier, like booking at a restaurant, paying for parking, or getting live traffic updates without taking your smartphone out, plugging in your headset, and getting distracted in the process. It will be a truly smart and hands-free (voice-activated) experience to deliver a car.
Smart devices need the best network
While eSIM sounds fantastic in theory, the real benefit is only to be enjoyed over well-equipped and future-proof cellular networks. The eSIM requires specific secure applications that support the mobile operator pushes over the network to the smartphones. Of course the mobile operators will use complex coding and other methods that ensure that said code works securely. These apps or services can range from infotainment to creation capabilities mobile payments.
The customers from different parts of the country will finally benefit from the seamless LTE connectivity thanks to the pan-Indian availability of the 4G LTE networks of different mobile operators such as Airtel, Jio and Vodafone.
More than smartphones and calling
With the eSIM, the mobile operators are destined to go beyond just supporting the bare minimum: smartphones. The next generation of the Internet of Things will drive the growth of connected devices such as smart wearables and connected ecosystems such as cars and smart ones homes and offices. The basic idea is to enable seamless (no pun intended) connectivity of the smart gadgets using reprogrammable software and without worrying about protecting and inserting a physical SIM card. So you no longer need your phoneIt’s connection to your smartwatch or health band to sync your data. Those smart devices could do that independently.
