Myth-busting: these 'disadvantages' are not true!

Only a small number of premium phones, which everyone can't afford, currently support eSIM. Regular customers can't use an eSIM without spending a few dollars, which is one of the biggest disadvantages of eSIM cards. So, if you have an eSIM or are planning on getting one, there aren't many phone options available.

One of the common challenges faced with eSIM connectivity is network disconnections. This can be frustrating, especially when you rely on a stable and uninterrupted network connection for your mobile device. However, there are a few steps you can take to troubleshoot and resolve these issues.

And since eSIMs are used on connected devices, like any other technology, they are vulnerable to malware, social engineering, and phishing attacks.

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 by mail.

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.

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.

In your quest to find out which is better between eSIM and pSIM (which is the same as physical SIM) you might be wondering if one has better signal strength than the other. The good news is that neither type of SIM is better or worse signal-wise.

An eSIM makes it much easier to switch mobile networks. Instead of needing to order a new SIM, waiting for it to arrive, then inserting it into your phone, you can switch to a different network with a phone call or online. You also won't need to go hunting for a SIM 'ejector tool' to remove the old SIM from your phone.

Not all iPhones support eSIM. Compatible models include iPhone XS, XS Max, XR, and later, but there are exceptions in certain regions. Common problems like incompatible carriers, activation issues, network problems, software updates, and physical SIM interference can cause eSIM malfunctions.

Can someone hack my eSIM? ›

The short answer is that while no technology is entirely immune to security threats, eSIMs are designed with robust security measures, including hardware security, to minimize the risk of hacking. However, it's essential to be aware of potential vulnerabilities and take precautions to safeguard your digital identity.

The good news is that it is safe to use a travel eSIM, and using a travel eSIM does not open you up to financial frauds - let's take a look at why!

Saily – best eSIM provider in the USA overall

Saily is the best eSIM for USA travelers in 2024. The eSIM is developed by the team behind NordVPN, ensuring a reliable and convenient service. Like a regular SIM card, an eSIM enables activating your data plan easily.

Changing devices might not be straightforward

If you are using an eSIM and you need to change phones, chances are that you will need to contact your local provider to enquire how to transfer your eSIM. While Android and iOS have eSIM transfer tools, not all carriers allow an eSIM transfer.

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.

Does eSIM slow down your phone? An eSIM has nothing to do with the internet speeds or better cellular reception. It is just like a digital copy of your SIM card.

Traditional SIM cards and eSIMs are both affected by a variety of factors that influence signal strength. These include distance from the cell tower, obstructions, interference, and the device's antenna quality. The closer a device is to a cell tower, the stronger the signal.

FAQ How to switch from eSIM to physical SIM. Can I switch from eSIM to physical SIM? Yes, you can switch back from eSIM to physical SIM in seconds, in fact you can even use both of SIMs at the same time, your primary card for calls and message, and the eSIM for internet.
