Home - Industry blog - What is a Virtual SIM Card, and How Does it Work?
Reviewed by : Prasanta Raut
Are you aware that the digital SIM market will reach approximately $10.8 billion by 2025 globally? This is a clear indicator that the world of the virtual SIM card is well underway.
Take it from switching networks with a QR code to no longer needing a SIM card when you travel. Virtual SIM cards are making mobile connectivity more simple and smart.
This guide covers possible questions you may have about virtual SIM cards, what they are, how they work, and are changing the way we live digitally.
Table of Content
The virtual SIM card, also known as the embedded SIM (eSIM), is simply the digital version of a traditional SIM card that is in your mobile phones. Unlike SIM cards, virtual SIM cards do not have to be inserted and fit into a SIM card slot, as they are embedded in the device’s hardware.
Virtual SIM cards use eSIM profiles, or the carrier information that is stored digitally that can be changed or switched without requiring the old physical hardware.
You can think of your phone as a vehicle and the SIM card as the fuel. A physical SIM card is like going to the same petrol station to fill up your vehicle. A virtual SIM card, on the other hand, offers more options for fuel along the way so that you can choose the most appropriate one as you travel at home or overseas.
Virtual SIM cards are an innovation that acknowledges customer value and provides a modern mobile experience.
A virtual SIM card, or eSIM, is a newer version of a physical SIM card. Instead of taking a plastic card and placing it into your phone, the eSIM is built into your device. Here’s how it works:
An eSIM is a tiny chip that is already inside your phone when you buy it. You do not need to put anything in or take anything out.
Your mobile carrier sends you a QR code or set of instructions. You scan the QR code or follow the instructions on your phone, and your eSIM profile is downloaded to your device
Once scanned, your device connects to the network, and you can start using calls, SMS, and eSIM data.
If you want to switch carriers, you do not have to switch out a physical SIM card. You simply download a new eSIM profile from the new carrier.
You can store multiple eSIM profiles on one device (one for work, one for personal use) and switch between them seamlessly.
Utilizing a virtual SIM card, also known as an eSIM, provides multiple advantages over plastic SIM cards.
With an eSIM, you will no longer have to deal with the hassle of dealing with plastic cards and physical SIM slots. Everything is online. You can easily switch between eSIM profiles for work, personal use, or international travel without swapping a physical SIM.
Many of the latest phones and tablets, including iOS phones and Android phones, accept both eSIM and traditional SIMs, giving users the ultimate flexibility.
The use of an eSIM is very easy to activate. Simply scan the QR code that your eSIM carrier gives you and follow the onscreen instructions. There is no need to wait for a physical SIM to arrive in the mail.
Carriers can also remotely update eSIM profiles so that you have the most up-to-date data plan and access to any reliable mobile network.
When manufacturers eliminate the SIM card slot, it allows them to make devices smaller, cheaper, and much more stylish.
Moving away from plastic SIM cards and physical SIMs lowers production costs and encourages innovation focused on sustainability. Less reliance on plastic leads to a more sustainable mobile ecosystem.
Frequent travelers appreciate the international eSIM feature. You can activate an eSIM plan for countries such as the United Kingdom or Puerto Rico within some seconds.
You don’t need to hunt down local mobile carriers or fumble with SIM cards. Just download the plan and activate your eSIM for immediate worldwide call access.
An eSIM card is built into your device, making it substantially less easy to lose or steal. Some eSIM profiles even possess advanced security features, such as disabling or wiping an eSIM profile after an excessive incorrect login attempt.
With eSIM technology, you can manage and operate multiple eSIM profiles on just one device. You may want one for personal calls, another for your work calls, or separate data plans for different areas.
Setting up a virtual sim card is designed to be user-friendly and straightforward. Here’s how you can get started:
Step 1: Check Device Compatibility
Step 2: Contact Your Carrier
Not all mobile carriers offer virtual SIM cards, so reach out to your eSIM carrier or visit their website. They can provide you with an eSIM profile, often delivered through a QR code.
Step 3: Activate Your eSIM
Once you have your QR code:
Follow the onscreen instructions to complete the setup. This step may involve downloading the eSIM profile and confirming details like your data plan.
Step 4: Configure Your Data Plan
Step 5: Enjoy the Flexibility
With your virtual sim card set up, you’re ready to enjoy a host of benefits of eSIM like:
It’s a simple yet revolutionary change in how you manage your mobile networks.
📓 Reminder: every carrier may have slightly different processes. Always refer to the specific instructions provided by your eSIM carrier, and if needed, consult their customer service for personalized assistance.
virtual SIM cards provide great utility in various applications and scenarios, such as the following:
eSIMs allow travelers to avoid high roaming charges by switching quickly and easily to local carriers; you will be able to stay in touch without having to purchase and swap out physical SIM cards.
eSIMs allow workers to keep personal and work numbers separate and allow businesses to manage multiple virtual phone numbers across their devices.
eSIMs support the functioning of devices like smartwatches and connected cars, allowing devices to run without physical SIM cards and improving the efficiency of management.
eSIMs help students studying abroad stay connected with family, friends, etc., at home. They won’t have to worry about losing or misplacing physical SIM cards and can switch between carriers or eSIM plans easily.
eSIMs are useful in healthcare, transportation, and other categories for effective communication between professionals and patients, as well as efficient fleet management.
While virtual SIM cards and traditional SIM cards achieve the same basic outcome of connecting you to a mobile network, they differ in how they function and what they offer.
A traditional SIM card is simply a chip that is inserted into your device, but a virtual SIM card which is also known as an embedded SIM (eSIM) comes pre-installed into the device’s hardware and can be activated with a mobile plan digitally.
Understanding virtual eSIM cards and how they differ from traditional SIM cards can help you decide which solution is best for your needs, whether you prioritize the convenience of use, ease of travel, or use with multiple networks.
Now you have a clear idea of what a virtual SIM card actually is. The beauty of virtual SIM cards is that your phone doesn’t need a physical SIM card.
Whether you’re making a virtual call from abroad or switching eSIM data plans between business trips, it brings the flexibility today’s users need.
Virtual SIM cards are a smarter, more flexible, and modern method of communication. Besides that, It is more convenient and eco-friendly to the nature.
