Why eSIM Is Safer Than Public Wi-Fi
When traveling the world, we rely on the internet for everything – from navigating routes and calling a taxi to translating phrases and booking accommodation. One of the most common ways to get online is through public Wi-Fi in cafés, hotels, or airports. However, there’s a major drawback: it’s not secure.
In this article, we’ll explain why eSIM is a much safer way to stay connected – especially when you’re abroad.
What’s Wrong with Public Wi-Fi?
Public networks often:
- Don’t require a password, or use a shared one for all users
- Don’t encrypt your traffic – everything you send can be intercepted
- Are easy to fake – attackers can create a network with a similar name, and you might connect to it without realizing it
Through such networks, attackers can:
- Steal your login credentials and passwords
- Gain access to your banking information
- Monitor your messages and online activity
- Replace real websites with fake ones (e.g., a fake banking page)
Even if you’re just checking your email or searching for a restaurant, the risks are real.
Why Is eSIM Safer?
1. You use a mobile network, not a public access point
An eSIM connects your phone to a mobile network, which:
- Encrypts all traffic by default
- Is protected against spoofing
- Doesn’t rely on unknown third-party users
Your data is transmitted through a secure private connection – just like at home.
2. No Need to Connect to Unreliable Networks
With eSIM, you have constant internet access and no need to hunt for free Wi-Fi. This greatly reduces the risk of accidentally connecting to a fake or compromised network.
3. Protection from Man-In-The-Middle (MITM) Attacks
Public Wi-Fi is often used for MITM attacks – where a hacker positions themselves between you and the internet. With eSIM, this scenario is virtually impossible, as your traffic travels through the secure infrastructure of a mobile network provider.
4. Persistent Device Identification
An eSIM is a unique digital profile tied to your specific device. Your mobile provider always knows who you are and can offer an extra layer of protection against suspicious activity, fraud, or service disruptions. If your phone is lost, your eSIM can be remotely deactivated.
The combination of eSIM + VPN is the most secure option for travel. Even without a VPN, eSIM offers a stable, encrypted connection that’s significantly more secure than any public Wi-Fi network.
