Even if you aren’t tech savvy, chances are you’ve at least heard of a Subscriber Identity Module (SIM) card. They’re the small cards located in your phone that help you connect to your wireless carrier’s network and use your plan.
Now, embedded SIM cards (eSIMs) are in the spotlight. While you may not be sure how they’re different than physical SIM cards, why you might need them, which devices have them, and how to use them, we’re here to help answer those questions.
What's the difference between an eSIM vs a physical SIM card?
An eSIM is a digital version of the physical SIM card—identifying your device virtually to provide network connection. It’s programmable remotely via software and is built into newer smartphones, meaning you wouldn’t have to go purchase a new SIM card if you wanted to swap phones or wireless carriers. eSIMs are used in tablets, smart watches, drones, and even cars. They’re basically space-saving gamechangers for connectivity.
What can eSIMs do?
Since they’re embedded in devices and are programmable remotely, it can open a whole new world of flexibility when it comes to managing your phone and service plans. You can add plans, add a new number, and even connect to a different carrier. For example, you cantest outT-Mobile’s network for FREEbefore you switch, while still keeping your current phone number and carrier. Additionally, you can easily switch to a prepaid plan on iPhone with ourT-MobilePrepaid eSIM App.
Let's say you have one smartphone for work and a second phone for your personal life. If your device is equipped with eSIM, you can have both lines hooked up to the same device, giving you the convenience and control to toggle between those lines straight from your phone. This saves you money because with eSIM, you don’t need two separate devices.
Small, medium, and largebusinessescan benefit from eSIMs, as they make it possible to change or update wireless service remotely on multiple lines at once—whether you have five employees or five thousand.
If you’re traveling internationally, you no longer need to buy a second physical SIM card when you arrive at your destination. eSIMs let you easily add an international plan to your device that starts working the moment you arrive in another country, giving you hassle-free flexibility.

An eSIM is a digital version of the physical SIM card—identifying your device virtually to provide network connection. It's programmable remotely via software and is built into newer smartphones, meaning you wouldn't have to go purchase a new SIM card if you wanted to swap phones or wireless carriers.
Unlike traditional SIM cards, eSIMs are integrated directly into your device. They remove the need for physical swapping, allow for the storage of multiple accounts, and greatly improve convenience and durability. eSIMs are especially beneficial for international travelers and devices with limited physical space.
Device manufacturers are also hesitant to adopt eSIM technology due to concerns about its potential impact on their business models. Integrating eSIM technology into devices requires significant research, development, and testing investment, with no guarantee of widespread adoption or acceptance from consumers.

Each SIM Card whether it is a eSIM or the physical SIM Card can only have one mobile number for each SIM Card. The eSIM will have a different mobile number, and so would the physical SIM Card. Using the eSIM or physical SIM Card on a smartphone can only be done with the same device (Two mobiles number with one phone).
The basic eSim Card plan costs $4 weekly, offering 1 GB of global data. The 3 GB plan is $12 monthly for those needing more data. Moreover, the 5 GB and 10 GB plans are available at $19 and $34 per month, respectively. For heavy data users, eSim Card provides a 20 GB plan at $60 monthly.
Now, let's address the burning question: does installing an eSIM change your phone number? The answer is generally no. When you install an eSIM, it doesn't directly alter your phone number. Your phone number remains the same, and you can continue to use it as you normally would.
All iPhone models that support eSIM can have multiple eSIMs and use Dual SIM with two active SIMs at the same time. You can use Dual SIM by using a physical SIM and an eSIM. iPhone 13 models and later also support two active eSIMs. iPhone models without a physical SIM tray support two active eSIMs.
eSIM is more secure than a physical SIM because it can't be removed if your iPhone is lost or stolen. With eSIM, you don't need to obtain, carry and swap physical SIM cards, which can also be lost, or wait for them to arrive in the post before you leave.
The short answer is no, not really. An eSIM itself doesn't use more battery than a physical SIM. However, if you're using your phone with two lines (one eSIM and one physical SIM), your phone must maintain a connection to two networks. This can use more battery because your phone is doing extra work.
The eSIM eliminates the logistical hassle of getting a physical SIM card. You won't have to look for a store or wait for your SIM to be delivered by mail. No more looking for an ejector tool, or a paperclip to change SIMs! eSIM is also ideal if you are a frequent traveler.
