Advantages of eSIMs Over SIM Cards - Why You Should Switch

With new phones coming out with plenty of brand-new features, it may be challenging for you to decide whether to invest in a new phone or stick it out with your current one. You might be asking yourself if the upgrade is remotely worth your money and time. This is particularly true for a new feature known as eSIM technology, considering the advantages of eSIMs over SIM cards.

If you do not know what it is, an eSIM is a feature in which a phone has an embedded SIM card. It works much like traditional SIM cards that provide a connection to a mobile network, and it is used in other devices, such as tablets, laptops, and smartwatches. That said, there are differences between eSIMs and SIM cards.

In this article, we will share the similarities between the two options and the advantages of eSIMs to help you decide whether investing in a new phone solely for eSIM-compatibility is worth it.

Similarities of SIM cards and eSIMs

If you own a phone, you are probably familiar with SIM cards. eSIMs are in many ways quite similar to SIM cards. As mentioned earlier, they allow phones to connect to a mobile provider's network in a secure way using similar authentication mechanisms. They can provide some mobile analytics besides wireless connectivity. Put simply, an eSIM is pretty much a normal SIM card chip built into smart devices, although it comes with unique advantages.

The advantage of eSIMs over SIM cards

One of the most significant advantages of eSIMs is its security. Unlike SIM cards that can be swapped or cloned, eSIMs provide better security measures by being built into the device electronics, while deploying a whole host of security features and certificates.

Another advantage is that eSIMs are much harder to damage and lose. This is because eSIMs are embedded deep into a phone, while SIM cards can easily get tossed around and damaged.

You cannot technically lose an eSIM chip because it is not something you take out, but you can disable it or delete an eSIM profile using your device settings. The only way you are going to lose it is if you lose your phone.

Now, if you think you will be stuck with one mobile service provider, think again. eSIM feature enables you to store multiple cellular plans and profiles i.e. eSIMs. As a result, you will not have to keep swapping SIM cards when traveling around the world.

Finally, as hardware element, SIM cards have to be physically delivered to the end user either by mail or through a shop, which is very inconvenient and cumbersome. On the other hand, eSIM plans are delivered digitally (e.g. using QR codes or activation codes) and accordingly mobile users can immediately get them online in few clicks.


Are these advantages something you can take advantage of? If not, then upgrading to an eSIM-powered phone might not be worth it. However, if you have multiple devices locally, frequently travel internationally, and you often find yourself purchasing new SIM cards all the time, an eSIM can be genuinely beneficial for you. Thanks to the benefits it provides, it can make accessing any cellular network much simpler, allowing a smoother and headache-free wireless experience.
