What is an eSIM?

Let’s start the guide to eSIMs from the basics – what exactly is an eSIM?

eSIM stands for “embedded SIM card.” Just like your traditional plastic sim, it is also a tiny chip that connects you to a network.

But, instead of being a plastic chip, an eSIM is built into your device.

This means you don’t have to insert a physical SIM card into your phone. The eSIM is already integrated inside the device during manufacturing. All you need to do is activate it using a QR code or mobile app provided by the carrier.

With an eSIM, you can easily switch between mobile carriers without swapping physical SIMs.

How does an eSIM work?

Now that we've covered what an eSIM is, let's dive into how it works.

Think of eSIM as a digital SIM card – a reprogrammable chip that lets you download data on the go.

So, there’s no need to search for a physical SIM or hassle vendors to switch carriers or data plans. Instead, just purchase and download an eSIM plan to instantly connect to a mobile network.

Here's how to activate an eSIM:

  • Check Your Phone:

First things first, make sure your phone supports eSIM. Most newer phones do, but it's good to double-check. We have curated a list of devices that are compatible with eSIMs below. Use it to know if your device is compatible with eSIM or not.

  • Get Your eSIM Code:

Reach out to your mobile carrier or eSIM plan provider and get an eSIM QR code or activation code. You can find it on their website or app too.

  • Scan or Enter the Code:

If you've got a QR code, open your camera and scan it. If it's an activation code, go to your phone's settings, add a cellular plan, and type it in when it asks.

  • Follow the Steps:

Your phone will talk to your carrier for a sec to confirm everything. Just follow any on-screen instructions, and you'll be good to go.

  • Pick Your Line:

If you've got a phone with dual SIM support, decide which line you want as your main one for calls and texts.

  • Restart:

Your phone might ask for a quick restart. It's like a little break for your device.

  • You're All Set:

Congrats! Your eSIM is activated and ready to roll. Switch carriers and use data plans hassle-free.

Note: The exact steps might vary depending on your phone and carrier, but this should give you a good idea about how to activate your eSIM. If you run into any issues, don't hesitate to contact your carrier's support.

eSIM Vs Physical SIM

To understand eSIMs better, it is good to learn how different they are from physical SIMs.

We have jotted below the pros and cons of both eSIMs and physical SIM. Check them out:

Physical SIM Pros

  • Widespread Availability: Physical SIM cards are widely available, and you can easily find them at carrier stores, retail outlets, or online stores.
  • Instant Use: When you purchase a new SIM, you can pop it in right away and start using your mobile service immediately.
  • Simple Setup: Inserting a physical SIM is straightforward, and most people know the process.
  • Easy to Swap: If you have multiple devices, you can easily switch your SIM card between them to use the same mobile number.
  • Offline Use: Removing the physical SIM allows you to go offline, which can be great for privacy or focus.

Physical SIM Cons

  • Prone to Loss or Damage: Physical SIM cards are small and easy to misplace. They can also get damaged or scratched quite quickly.
  • Inconvenient for Switching Carriers: Switching between mobile service providers requires physically obtaining and replacing the SIM card. And that’s not easy all the time.
  • Limited Space in Dual SIM Devices: If your phone has dual SIM support, using a physical SIM might take up space that could be used for other purposes.
  • Security Concerns: Physical SIMs can be easily removed, making them susceptible to theft or unauthorised access.
  • International Roaming Hassles: Travelling abroad often involves purchasing and swapping physical SIM cards for local carriers, which can be time-consuming and costly.

eSIM Pros

  • Convenience: eSIMs eliminate the need for physical cards. You can remotely activate an eSIM, making it quick and hassle-free to set up your mobile service.
  • Seamless Carrier Switching: With eSIMs, changing mobile service providers is as easy as a few taps on your device. No need to visit a store or swap physical cards.
  • Enhanced Security: eSIMs are more secure since they are embedded directly into the device. This means there is a lower risk of theft or unauthorised SIM card removal.
  • Remote Reprogramming: eSIMs can be reprogrammed and updated remotely, making it simple to switch between carriers or data plans without changing physical components.
  • Ideal for Travellers: eSIMs are traveller's best friends. You can switch between local carriers while abroad without the hassle of buying and inserting new physical SIM cards. Also, eSIM plans save you a lot of money when compared to international roaming charges.
  • Space Efficiency: eSIMs take up less physical space in devices, allowing for slimmer and more compact designs.
  • Dual eSIM Support: Some devices support multiple eSIMs, giving you the flexibility to switch between different mobile service providers without any physical intervention.

eSIM Cons

  • Limited Availability: Not all carriers and devices support eSIM technology, which may limit your options for using this feature. Again, see the list of devices compatible with eSIM below to know if you are eligible or not.
  • Compatibility Concerns: If you have an older device, it may not support eSIMs, requiring you to use a physical SIM instead.
  • Dependent on Network Coverage: As with any mobile service, eSIM functionality relies on network coverage. It will be difficult to get a good connection In remote or poorly covered areas.


The Verdict: Why Should You Switch to eSIMs?

After going through the pros and cons, there’s no doubt that eSIMs win the war. Whether you're a globe-trotter or a tech enthusiast, eSIMs offer a world of benefits that are hard to ignore. To make your decision easier, here are some of the best reasons why we think you should make the switch.

  • You can use eSIMs anywhere, anytime.
  • They are highly safe and secure.
  • eSIMs can store multiple carrier profiles.
