· 4 min read
In today's digital age, making phone calls has become more convenient than ever. Thanks to the advances in technology, it is now possible to make phone calls and stay connected with your loved ones using a data-only eSIM.
What is an eSIM?
An eSIM, or embedded SIM, is a small chip embedded in your mobile device that replaces the need for a physical SIM card. It allows you to store multiple carrier profiles simultaneously, giving you the flexibility to switch between different network operators without changing your SIM card.
How Does a Data-Only eSIM Work?
A data-only eSIM functions similarly to a traditional SIM card. It enables your device to connect to cellular networks, allowing you to make phone calls, send text messages, and access the internet. However, unlike a physical SIM card, you can activate and manage your eSIM directly from your device, without the need to visit a store or handle a physical card.
When you activate a data-only eSIM, your device establishes a secure connection with the network operator of your choice. This connection allows you to access the internet and make phone calls using the network's infrastructure. The eSIM technology ensures a seamless and reliable connection, eliminating the need for physical SIM cards and simplifying the process of switching between different network operators.
Furthermore, the ability to store multiple carrier profiles on a single eSIM gives you the freedom to choose the best network for your needs at any given time. Whether you're traveling abroad and want to use a local network or simply want to take advantage of a better data plan, the flexibility provided by eSIM technology allows you to do so effortlessly.
Making Phone Calls with Your Data-Only eSIM
With the rise of digital communication, making phone calls has become more convenient and flexible than ever before. The use of data-only eSIMs has revolutionized the way we connect with others, allowing us to make calls using various methods and services.
Using VoIP Services
A popular method to make phone calls with a data-only eSIM is by using voice-over-IP (VoIP) services. VoIP allows you to transmit voice calls over the internet instead of traditional phone lines. Many popular applications like Skype, WhatsApp, Telegram, and FaceTime currently support VoIP.
By leveraging the power of the internet, VoIP services offer numerous advantages. Firstly, they eliminate the need for a physical phone line, making it possible to make calls from any device with an internet connection. Whether you're using a smartphone, tablet, or computer, VoIP services ensure that you're always connected.
Additionally, VoIP services often provide a range of features that enhance your calling experience. These features can include call forwarding, call recording, voicemail transcription, and even video calling capabilities. With such versatility, you can tailor your phone calls to suit your specific needs. Of course, the caveat is that the person that you are trying to call will need to have the same application installed.
Does my phone number change if I install a data-only eSIM?
No, it doesn't! Installing a data-only eSIM does not change the phone number that is registered to your VoIP application. This also means that you do not need to worry about your families and friends seeing a new, unrecognisable number when you call them. And they will still be able to reach you on WhatsApp, FaceTime, or any of your preferred apps on your primary line.

Making Phone Calls Over Social Media
Aside from VoIP services, if you are already connected to the Internet via your data-only eSIM, you also have the option to make calls over social media! Social media platforms like Facebook and Instagram have support for voice and video calls, so you can also make use of your social media accounts to connect with your family and friends!
Making Phone Calls with Your Primary Line
You can also make phone calls using your primary line. One benefit of eSIMs is that you can have multiple profiles, each for a different use case. This means that you can have a data-only eSIM activated for your data and connectivity needs, while still keeping your primary line active for phone calls.
Keep in mind that if you want to use your primary line for international calls, you'll need to first make sure that your plan includes support for international calls and roaming. Also note that international calls could rake up much higher charges, so you might want to keep your calls short.
Setting Up Your Data-Only eSIM
Purchasing a Data-Only eSIM
To get started, you'll need to purchase a data-only eSIM from a service provider or directly from your device manufacturer. There are various options available, so take the time to research and choose the eSIM that meets your requirements.
When purchasing a data-only eSIM, it's important to consider factors such as coverage, data plans, and pricing. Different service providers offer different coverage areas, so make sure the eSIM you choose provides coverage in the areas you frequent the most. Additionally, compare data plans to ensure that you're getting the best value for your money. Some eSIMs offer unlimited data, while others have data caps that may or may not suit your needs.
