What is an eSIM and Why It Matters Today
If you have heard about eSIM and wondered how they are different from the plastic SIMs we have been popping into phones for years — you are not alone. Think of an eSIM as a smart, digital version of the traditional SIM, built directly into your device. It eliminates the need to physically swap cards and lets you switch carriers with a few taps.
Here is why they matter:
- No more fumbling with SIM ejector tools.
- Quick carrier switch, especially handy when traveling.
- Perfect for dual-line users (work + personal).
- Safer — you cannot lose what is not there physically!
eSIM vs Physical SIM: Key Differences Explained
Before jumping into the how-to, let us break down the differences. This comparison is crucial, especially if you are deciding between sticking to your plastic SIM or going digital with eSIM.
Here is a simple table:
| Feature | eSIM | Physical SIM |
| Form | Embedded in your device | Physical chip you insert |
| Activation | Over-the-air (QR code or app) | Requires manual insertion |
| Carrier Switching | Fast and remote | Requires SIM swap or store visit |
| Device Transfer | May need carrier reactivation | Just pop out and re-insert |
| Security | Cannot be lost or stolen | Easy to lose |
| Device Support | Supported by newer phones (e.g., iPhone 14, Pixel 8) | Universal on all phones |
In plain words:
If you are all about speed, flexibility, and modern tech, eSIM is the way forward. If you are still rocking older devices or frequently switch phones, the physical SIM may still be your friend.

Can You Use an eSIM and Physical SIM in the Same Phone?
Absolutely — and that is one of the biggest wins for dual SIM users today. Most modern smartphones let you use both an eSIM and a physical SIM side-by-side. It is especially helpful if:
- You want to keep your work and personal numbers separate.
- You are traveling abroad but still want to receive calls on your home number.
- You want to use one SIM for talk and another for data (especially useful with a hotspot setup).
Some phones like the iPhone 13 or newer even let you use two active eSIM at the same time.
Can You Use Two eSIM in One Phone?
If you are someone who hops countries or switches plans often, this is your dream scenario. And yes — many new smartphones support multiple eSIM profiles.
Here is what you need to know:
- iPhone 13 or newer: Store 8+ profiles, use 2 eSIM at once.
- Google Pixel 7/8: Store 5 profiles, activate one at a time.
- Samsung Galaxy S23 Ultra: Dual eSIM support enabled.
No need to juggle SIM trays — just pick and switch. If you are looking for the best eSIM plans for hotspots, Lyca Mobile USA offers affordable options with 5G network support.
Can You Use an eSIM With a Regular SIM?
This is a common question, especially if you have already got a Lyca Mobile SIM card and are considering adding an eSIM from another provider.
Here is the short answer:
✔ Yes, you can — and it works like a charm!
Your device just needs to support dual SIM functionality. You will typically get separate icons in your status bar for each line, and you can assign one for calls and one for data. It is a flexible setup that makes managing two lines a breeze.
How to Move eSIM Across Phones
Unlike physical SIMs, which you can yank out and insert elsewhere, eSIM requires a reactivation process. But the good news? It is all digital.
For iPhone users:
- Go to Settings > Cellular > Add eSIM
- Choose Transfer from another iPhone or scan the QR code
- Follow prompts and done!
For Android users:
- Head to Settings > Network & Internet > Mobile Network
- Tap Add Carrier and scan the QR code
Tip: Before switching, always delete or deactivate the eSIM profile from the old device. Read out guide on switching from a physical SIM to an eSIM.
Can You Use an eSIM on Multiple Phones?
One of the quirks of eSIM is that they are tied to your device’s unique ID. So, no — you cannot use the same eSIM on two phones at once.
But here is what you can do:
- Switch devices by transferring the eSIM (via carrier support or app).
- Set up multiple eSIM on each phone if supported.
Bonus Tip: Use Wi-Fi calling or number sharing features to mimic this across devices.
Conclusion: Why eSIM Are the Future
Whether you are managing multiple devices, traveling often, or just want tech that simplifies your life — eSIM offers a smarter, cleaner, and more secure way to stay connected. And best of all? They now play nicely with your good old physical SIM.
