Planning an international trip and heard about eSIMs, but still hesitant? Don’t worry – you’re not alone! Many travelers have misconceptions about eSIM technology when it comes to using mobile data abroad. These widespread eSIM myths often prevent people from enjoying the huge advantages of digital SIM cards. From security concerns to cost worries, there are plenty of misconceptions about mobile data abroad. In this comprehensive guide, we’ll debunk the most common eSIM myths and show you the truth about virtual SIM cards – and why they are the best alternative to expensive roaming. Let’s break down these misconceptions and see why eSIMs are easier and more useful than most people think.
What is an eSIM? The Basics
Before debunking myths, let’s clarify what an eSIM actually is. An eSIM (embedded SIM) is a built-in digital SIM card found in modern smartphones, tablets, and smartwatches. Unlike physical SIM cards, you don’t have to swap them out. Instead, mobile profiles are activated digitally via QR code or app.
Technical Foundation of eSIM Technology
eSIM technology is based on internationally standardized GSMA protocols. It allows multiple mobile profiles to be stored on one device and makes switching between them flexible. This innovation is transforming the way we stay connected while traveling.
Differences Compared to Physical SIM Cards
The key difference lies in flexibility. With physical SIMs, you need to swap cards manually. With eSIMs, you can activate new plans within minutes. This makes eSIMs the perfect solution for international travelers.
Myth 1: “eSIMs are insecure and easy to hack”
The truth: This widespread myth is unfounded. In fact, eSIMs are more secure than physical SIM cards. They use the same proven encryption technology, with added security benefits.
Security Features of eSIMs
- Remote SIM Provisioning (RSP) ensures secure over-the-air updates and profile management.
- Multi-level authentication makes manipulation virtually impossible.
Security Compared to Physical SIMs
Because eSIMs are built into the device, they can’t be physically stolen like a regular SIM. eSIM profiles can also be deactivated remotely if your device is lost or stolen.
Myth 2: “eSIMs don’t work in all countries”
The truth: Modern eSIM providers cover 200+ countries and regions worldwide – far more than most traditional roaming packages.
Global eSIM Coverage
Top providers like Airalo, Holafly, and Yesim offer worldwide coverage across the Americas, Europe, Asia, and Africa. The official GSMA standards guarantee compatibility and quality.
Regional Exceptions
Only a few countries restrict eSIM use, such as mainland China. In Hong Kong and Macau, eSIMs work fine. For nearly every other travel destination, there are suitable eSIM plans.
Myth 3: “eSIMs are much more expensive than local SIMs”
The truth: In many cases, eSIMs are cheaper than buying a local SIM card – especially in developed countries. They are always far cheaper than traditional roaming.
Price Comparison: eSIM vs Local SIM
- USA, Canada, Australia, New Zealand: eSIMs are often cheaper than local SIMs.
- Local SIMs may cost $40–50, while comparable eSIMs start at $15–20.
- Only in very cheap regions (e.g. Southeast Asia, parts of Latin America) are local SIMs sometimes cheaper.
Hidden Costs with SIMs vs eSIMs
- No shipping costs
- No activation fees
- No SIM card charges
What you see is what you pay. Plus, no wasting time searching for stores or dealing with language barriers.
Myth 4: “eSIMs have poor network quality”
The truth: Network quality depends on the provider and local partner networks, not the SIM type. Reputable eSIM providers work directly with premium carriers.
Partner Networks
eSIM providers connect you to the same towers as locals. Data speed and coverage are the same as with a local SIM.
4G/5G Support
Modern eSIMs support LTE and 5G, just like local SIMs. Speeds depend entirely on the local infrastructure, not on whether you use an eSIM.
Myth 5: “eSIMs are complicated to install”
The truth: Installing an eSIM is usually faster and easier than inserting a physical SIM.
Easy Installation in 3 Steps
- Scan the QR code.
- Follow on-screen instructions.
- Done in under 5 minutes.
See the official Apple eSIM setup guide for how simple it really is.
Common Issues
The main problems are user mistakes: scanning the wrong code or lacking Wi-Fi during setup. With a stable connection, installation works almost every time on the first try.
Myth 6: “You can’t make calls with eSIMs”
The truth: Most travel eSIMs are data-only, but calling is no problem via apps. Some eSIMs even include phone numbers.
Data-Only vs Full-Service eSIMs
- Most travel eSIMs are data-only.
- WhatsApp, Telegram, and FaceTime cover all calling needs.
- Some providers offer full voice plans.
Alternative Communication
- WhatsApp, Skype, FaceTime, and similar apps replace traditional calling.
- Your WhatsApp number stays the same.
- VoIP apps provide cheap international calls.
Myth 7: “eSIMs only work on the newest smartphones”
The truth: eSIM support has existed for years.
Compatible Devices
- iPhones since XS (2018)
- Samsung Galaxy since S20
- Google Pixel since Pixel 3
- Many Huawei, OnePlus, and others
- Tablets and smartwatches increasingly support eSIM
How to Check Compatibility
Go to your device’s settings. If you see “Add eSIM” or “Add Mobile Plan,” your phone supports it.
Myth 8: “eSIMs drain more battery”
The truth: eSIMs use the same technology as physical SIMs. Power consumption is identical.
Technical Background
Battery usage depends on signal strength, data use, and network switching – not on whether you use an eSIM.
Dual SIM Usage
If using both physical SIM and eSIM simultaneously, battery use may rise slightly. But modern smartphones optimize this automatically.
Myth 9: “eSIMs can’t be used for hotspots”
The truth: Hotspot functionality depends on your device, not the SIM. Any data connection (SIM or eSIM) can be shared.
Hotspot Tips with eSIM
- Choose an eSIM plan with enough data.
- Stay in areas with strong reception.
- Use 5GHz Wi-Fi for best performance.
Myth 10: “eSIMs are just a temporary technology”
The truth: eSIMs are the future. Physical SIMs will disappear in the next few years.
Industry Trends
- Apple already sells eSIM-only iPhones in the US.
- Other manufacturers are following.
- SIM slots will likely disappear within 5–10 years.
Conclusion: eSIMs Are the Best Choice for Travelers
Most eSIM myths are outdated or flat-out wrong. eSIMs are secure, widely available, often cheaper than alternatives, and technically reliable. They are the best option for modern travelers who want to stay connected abroad without overpriced roaming. Instead of wasting money or time on local SIMs, simply activate an eSIM before your trip and enjoy worry-free mobile data. The future of travel is digital – and it’s powered by eSIM.
