Physical SIM cards have been around for a long time, but now they seem to be on their way out. Why? A very smart new technology, eSIM, is here.

A SIM, which stands for “Subscriber Identity Module”, basically contains information that proves your identity to a carrier. In other words, the SIM card is what tells a carrier if you’re the one – and without it, the carrier won’t know you’re subscribed to their network, and thus won’t let you use their cell tower. Will let

But you have not come here to learn about a standard SIM card. Newer phones like Pixel 4, iPhone 11 Pro, and Motorola Razr boast of eSIM support, so it becomes important to know the exact meaning. Here’s everything you need to know about the new eSIM.

eSIM Meaning

ESIM Ka Matalb Hindi Me;

ESIM is a shortened version of Embedded SIM, where SIM stands for Subscriber Identity Module. So, an eSIM is an Embedded Subscriber Identity Module.

ESIM is a SIM card that is embedded in a mobile device. The SIM stores all the information that is required to identify and authenticate the mobile subscriber.

An eSIM will come in the form of an integrated SIM chip that cannot be removed from a device and is not required.

ESIM is sometimes called eUICC (embedded Universal Circuit Card). The information on the eSIM will be rewritable by the operators. Operators may be able to update your identification information online. So now you will not need a new SIM for the new operator.

About eSIM in English

What is eSIM?

An eSIM is an electronic SIM card. As the name suggests, it is used in place of a physical plastic SIM card, which cannot be removed.

The first time we brought this hardware to the Samsung Gear S2 3G was in 2016. However, it was the Apple Watch 3 that really brought eSIM technology into the limelight. eSIM can be found on Pixel 2 smartphones, although UK carriers do not currently support this technology for Google’s current flagships.

The idea behind eSIM on the iPhone XS and iPhone XS Max is to enable the first dual-SIM iPhone. Instead of adding an extra slot for an additional Nano-SIM. You’ll be able to subscribe to the network using your phone just like you do on cellular-enabled iPads with an Apple SIM.

Why should you care? One of the advantages of eSIM is that it is slightly smaller than the size of a nano-SIM. This is what makes ultra-compact gadgets like watches so well suited, where there’s no room for a normal SIM.

eSIM Technology
An ESIM is non-removable and is embedded in the phone along with other internal components. You don’t have to remove it.

With such an embedded standard, the idea is that you can switch to a new operator without having to insert a specific SIM card. All this is done through software.

For example, the same Apple Watch 4 can be used on Verizon, T-Mobile or Sprint in the US. In the UK, the Apple Watch 4 can be used on EE or Vodafone.

With eSIM, your phone has some new settings dedicated to your SIM card that allow you to switch between files and carriers and manage accounts.

The Future of eSIM

Future of ESIM – Future of ESIM

The future of eSIM is still unclear, it could have significant implications. Deploying an eSIM based device can be expensive, complex and will involve some initial growing pains.

However, in the long run, it should cost less and also extend the life and usage of a device. Since you don’t have to worry about compatibility, you don’t have to change your device when you want to change the operator.

ESIMs are currently more common in IoT devices, tablets and cars but whether they will gain acceptance in smartphones is still unknown. In the automotive sector, manufacturers have started equipping cars with an eSIM to reduce manufacturing costs and simplify logistics. It is up to the car owner to go to the operator in whichever area they want to use.

Apple and Samsung are leading the pack within the telecom industry and are in talks with network providers to adopt eSIM for upcoming smartphones. Apple has already equipped some iPads with a single SIM, based on their version of the embedded SIM technology.

Although it is already programmed for Apple’s choice of network, you are able to decide which operator you want. Samsung is bringing GSMA enabled eSIM to its Gear S2 Classic 3G, which is a start.

With the iPhone XS and XS Max, we are getting a glimpse of a future where all phones will use eSIMS.

GSMA, an organization that represents the interests of mobile operators around the world, has announced a new SIM standard.

In addition to Samsung and Apple, AT&T, Deutsche Telekom, Etisalat, Hutchison Whampoa, Orange, Telefónica (current O2 owner) and Vodafone are also on board.

The network data that a standard SIM card carries will be rewritable on future eSIM devices, so you just need to make a phone call or two to change operators.

There’s another benefit to be had while travelling. If you’re going to be spending a lot of time overseas, where roaming charges can be extortionate, switching to a local network will be much easier.

The other problem with physical SIM cards is that they are currently available in two or three sizes.

Have you ever tried swapping your iPhone for an Android phone, or vice versa? Very often, they use completely different types of SIMs. This may require the use of an ugly and flimsy plastic adapter, or a brand new SIM, neither of which is ideal.

Advantage of eSIM

  1. eSIM is positive for environmental reasons as it will reduce the shortage of SIM cards.

You can change your carrier without getting a new SIM. You can change the carrier or your plan in your phone settings. This means less time speaking with the carrier, and giving commands and waiting for a new SIM. The software does everything.

  1. No problem with cutting SIM cards, or finding adapters.
  1. It will also increase consumer freedom and lower costs when it comes to using a local operator when travelling or relocating to another country.
  1. No hassle of disconnecting or replacing SIM cards while charging phones.

Some disadvantages of eSIM

Disadvantages of eSIM – eSIM: Some disadvantages

These benefits of eSIM cards are great, but there are also some disadvantages from the point of view of the users. If you are a user who changes their smartphone regularly or if you have multiple devices at home that have different SIM cards, this eSIM situation can complicate your life a bit more.

Every time you want to use a new device, you need to activate the SIM card through that device’s software. You cannot insert it into any other device by simply taking out the SIM as before.

If your phone’s battery is running out and you want to insert your SIM card into a friend’s phone to check something or make a call, this can also be a problem. With eSIMs, it won’t be fast or easy.

Devices Support eSIM

Which devices support eSIM?

Apple turns to eSIM for iPad Pro, Apple Watch Series 3 and Watch Series 4 and Series 5 as well as iPhone XS and XS Max and iPhone XR as well as new iPhone 11 and iPhone 11 Pro and Pro has done. Could next year’s iPhone 12 go completely on eSIM?

Google’s Pixel 2 also supported eSIM but it was originally only used for Google’s Google Fi in the US. The Pixel 3, Pixel 3 XL and the newer Pixel 4 and Pixel 4 XL do this as well.

Windows 10 has eSIM support inside and some devices with cellular modems – such as Qualcomm Snapdragon 850-powered PCs – can use eSIM as an alternative to sticking a traditional microSIM in the slot.

Which Networks support eSIM?

Which networks support eSIM?

eSIM is only available from a few carriers. You’ll need either a carrier app or a QR code that you can scan. Again, the carrier will need to support eSIM.

In the UK, EE, O2 and Vodafone support eSIM, although Vodafone is currently only supporting it for Apple Watch Series 3, 4 or 5 Cellular.

In the US, only AT&T, T-Mobile USA and Verizon Wireless support eSIM.

Away from traditional carriers, “global mobile network” Truphone has started selling eSIM data plans. These can be purchased through the ‘MyTruphone’ app. Truphone’s international plans operate in 80 countries, including Europe, the US and Australia.

This app was originally only available on iOS but is now available on Android for use with the Pixel 3, 3a and 4 (plus their XL versions). Truphone is currently offering 100MB of data completely free for new customers to try.

O2 recently launched eSIM on compatible Apple and Pixel phones. O2 says that customers just need to pop into your local store or get an eSIM pack or to download eSIM, call customer service.

eSIM, When it is available in India?

e-SIM, is it available in India?

eSIM technology came to India earlier this year when Apple launched the LTE version of the Apple Watch Series 3. Airtel and Jio are the first telecom operators in India to partner with carriers along with nine other countries where eSIM technology is supported.

Smart Automobiles Powered By eSIM

Although those smartphones and smart devices are in the pipeline, automobile enthusiasts will enjoy the first-ever connected car experience. Now eSIM support will power SUVs such as the Venue from Hyundai and the Hector from MG Motors in India.

With connected cars, eSIM will be equipped with in-vehicle services such as navigation, emergency/panic buttons, infotainment, automobile health, breakdown services, telematics and even diagnostics.

So many things will become easier such as making a reservation at a restaurant, paying for parking, or getting live traffic updates without taking out your smartphone, just plugging in your headset. It will be a truly smart and hands-free (voice-activated) car delivery experience.

How will eSIM work

If you have a physical and eSIM provisioning and are connected to two different networks, your iPhone will display both networks on the screen at the same time.

If the handset is on standby and both SIM and eSIM are provisioned, the customer will be able to receive calls and texts on both numbers. As you can see in the instructions below, you can then choose a “default” line that you call, use SMS, and one that uses iMessage and FaceTime. The second line is only for SMS and voice.

Alternatively, you can select Use Secondary for cellular data – if you are abroad and using local data eSIM.

You can store more than one eSIM on your iPhone, but you can only use one at a time.

You Settings > Cellular > You can switch eSIMs by tapping on Cellular Plans and tapping the plan you want to use. If you are in the UK it is mobile data. Then turn on this line.

If you have a QR code:

  1. Settings > Go to Cellular.
  2. Tap on Add Cellular Plan.
  3. Use your iPhone to scan the QR code you provided – you’ll need to enter an activation code that may be asked for.

Alternatively, you may be asked to activate your eSIM with the carrier app:

  • Go to the App Store and download your carrier’s app.
  • Use the app to purchase a cellular plan.
  • You will then add the data plan to your iPhone’s settings – see how that works below.

The Challenges of eSIMs

challenges of eSIM

Before we can move on to eSIM, every major carrier has to agree that eSIMs are the future. Again, phone makers will have to follow suit. If you know how this industry works, things like this take time.

But it would start with one career, which would later grow to two, and so forth. As I mentioned earlier, Google’s Pixel 2 is the first smartphone to use eSIM, but that’s only if you’re using the phone on Project Fi. For all others, it still uses a traditional SIM.

And, as we mentioned earlier, switching phones can be a little more time-consuming. You can swap your SIM card in a matter of seconds, where it will take longer to convert to eSIM.

But for most people, I think eSIMs will be great—especially those who aren’t tech-savvy. You must be shocked how many people don’t know how to swap SIM cards. For those people, eSIMs are going to be awesome.

last word:

eSIM Summary: Ultimately, it’s all about the smaller phones

‘Slimmer’, in the smartphone world, generally, is associated with better, so expect the moment eSIM really hits the mainstream. Apple, as always, will take credit for being on the technology front – even if a rival can beat it in the market with eSIM phones, as Google did (on a limited scale) with the Pixel 2, which features SMS. The feature is connected to Google’s US ‘Project Fi’ network.

Why would ESIM help users with the thinnest smartphone ever?

Well, physical SIM cards are deceptively simple things. They’re mainly waste plastic, the actual SIM part being that little gold bar you see on one side of the card. This means that removing the SIM card will free up a fair amount of extra space inside the phone, allowing manufacturers to slim the device and replace it evenly.

It is not only the space occupied by the SIM itself but also the housing, reader and tray system that supports it. With space in modern smartphones and every millimetre count at an absolute premium, eSIM will help bring slimmer phones.

Beyond Smartphones and Calling

With eSIM, mobile operators are destined to go beyond just minimal support. The next generation of the Internet of Things will enhance connected devices, such as smart wearables, as well as connected ecosystems such as automobiles, and smart homes and offices.

The basic idea is to enable (no pun intended) connectivity of smart gadgets with the help of reprogrammable software and without worrying about the security and insertion of the smart SIM card. So you no longer have to look at your phone’s connection to your smartwatch or health band to sync your data. Those smart devices would be able to do this independently.
