The eSIM or Virtual SIM is revolutionizing the way we connect to mobile networks, bringing along flexibility, portability, and cutting-edge technology. Whether you’re jetting off to a new country or using a phone that hasn’t been approved by local regulators, this guide has all the essential information you need about eSIMs.
Can eSIM Work on Non-Register Phone?
Absolutely! eSIMs can function on non-PTA-approved phones, provided the device is factory-unlocked and supports eSIM technology. However, keep in mind that local mobile operators in Pakistan, such as Jazz, might block unregistered IMEIs from accessing their networks. In these situations, opting for an international eSIM provider can help you get around this, especially for data-only services. Just a heads up: you won’t be able to make regular calls or send texts unless your device is PTA-registered.
How eSIM Works
An eSIM, or embedded SIM, is a programmable chip that’s built right into your device’s motherboard. Unlike traditional SIM cards, you don’t have to physically swap anything out. You can activate a mobile plan simply by scanning a QR code from your carrier or eSIM provider. This makes it super easy to switch carriers or profiles, especially when you’re on the go.
What eSIM Should I Use in Europe?
If you’re traveling in Europe, international eSIM providers like Holafly, Airalo, and Saily offer data packages that cover a wide range of countries. For instance, Holafly provides unlimited data eSIMs in the EU, which means you can say goodbye to roaming charges and the hassle of swapping SIMs in every country.
Who Invented eSIM?
The eSIM was created by the GSMA (GSM Association), the global organization that represents mobile network operators. Initially introduced in M2M (machine-to-machine) devices, eSIMs were later incorporated into smartphones, tablets, and wearables for consumer use.
Will eSIM Work on a Locked Phone?
If your phone is locked to a specific carrier, it will only support that carrier’s eSIM. You won’t be able to install an eSIM profile from a different provider unless you unlock your device. This is especially crucial for travelers who want to use international data plans.
eSIM for Non-register Phones
With international eSIMs, you can get around network restrictions for data usage, although voice calls and texts through the local network might still be unavailable. PTA ensures that SIM cards are assigned to the correct individuals which is essential for preventing fraud and misuse among the general population. SIM owner verification can be done by running a USSD code in Pakistan.
eSIM: Can You Make Calls?
Absolutely! You can make calls using eSIM as long as your mobile plan allows it. Traditional voice calls (over LTE or 5G) work just like they do with physical SIMs. If you have a data-only eSIM (often used for travel), you can still make calls through apps like WhatsApp, Skype, or FaceTime.
eSIM to Physical SIM
Switching from eSIM to a physical SIM is pretty straightforward. You just need to deactivate the eSIM profile and pop in a physical card from your carrier. Some phones let you switch between the two effortlessly, but not every model has that capability.
eSIM With Phone Number
Your eSIM can hold a complete mobile plan, which includes a phone number, data, voice, and SMS services. It functions just like a regular SIM in terms of the services it offers, depending on what your carrier provides.
eSIM Without Physical SIM
Yes, many of the latest devices (like US iPhones) can run entirely on eSIM, no physical SIM slot required. This makes it much easier for international travel and managing dual lines.
eSIM vs Physical SIM
| Feature | eSIM | Physical SIM |
|---|---|---|
| Swapping profiles | Instant (via QR code) | Requires ejecting SIM tray |
| Portability | Built-in | Removable |
| Security | Harder to clone | Easier to lose/clone |
| Usage | Dual SIM capability | Limited unless dual tray |
eSIMs are generally more convenient, secure, and flexible, especially for frequent travelers.
eSIM Activation
Activating an eSIM is usually a straightforward process that involves a few key steps:
1. Scanning a QR code provided by your mobile operator.
2. Downloading the eSIM profile to your device.
3. Confirming the activation through your device’s settings.
In Pakistan, Jazz has made this even easier with a dedicated eSIM management portal.
How Does eSIM Work
So, how does eSIM work? In a nutshell, eSIMs digitally store your network credentials. Your device connects to the carrier’s server via the internet to download and activate a profile, allowing you to connect without the hassle of swapping out a physical SIM card.
Now, about that eSIM QR code: it holds all the setup credentials for your carrier. When you scan it, your phone can download and apply the necessary settings. Make sure to keep this QR code safe, as you might need it if you ever want to reconfigure or switch devices.
eSIM Supported Phone:
Wondering which phones support eSIM? Here’s a quick list:
– iPhone XS and newer models
– Google Pixel 3 and later
– Samsung Galaxy S20 and newer
– Recent iPads and MacBooks
– Certain models from Huawei and Motorola
Always double-check with your manufacturer and carrier to ensure full compatibility.
Downsides of eSIM
Are there any downsides to eSIM? While they represent a leap forward in technology, they do have some drawbacks:
– Not every device supports eSIM.
– Switching devices can be more complicated than just swapping out a SIM card.
– Availability can be limited in some regions.
– Losing your QR code can make reactivation a hassle.
Despite these issues, for most users, the benefits of eSIMs far outweigh the negatives.
In conclusion, eSIM technology is paving the way for the future of mobile connectivity, especially for travelers, tech enthusiasts, and anyone seeking more control over their mobile experience. Whether you’re navigating restrictions or gearing up for your next European trip, getting to know eSIMs can help you save time, avoid headaches, and even cut costs.
