Is An eSIM Safe? What You Need To Know About Security And Risks

Quick Answer: Yes, eSIMs are safe—often more secure than physical SIM cards. They can't be physically stolen, are harder to clone, and offer remote deactivation if your device is lost. However, no technology is 100% risk-free.

This guide covers everything you need to know about eSIM security for travelers—from banking safety to SIM swap protection-with practical tips for staying secure in 190+ countries. Whether you're using Bitjoy for the first time or you're a seasoned digital nomad, you'll learn how to protect your connection anywhere in the world.

Is it safe to use an eSIM?

With the growing popularity of eSIM technology, many people wonder about its safety. Here, we answer common questions to help you understand how secure eSIMs really are.

Is an eSIM safe for banking?

Yes, eSIM is a secure option for banking transactions—in many ways, more secure than physical SIM cards. Here's why:

Physical security advantage: Unlike physical SIM cards that can be stolen and inserted into another device within minutes, eSIMs are embedded directly into your phone's hardware. A thief cannot physically remove your eSIM, which means they can't easily steal your phone number to intercept banking two-factor authentication codes.

Automatic deactivation: When you request a new eSIM from your carrier - for example, after losing your phone while traveling - the old eSIM profile is immediately deactivated remotely. This means that even if someone has your physical device, they cannot use your phone number to reset passwords or access your bank accounts once you've reported the loss.

Best practices for banking with eSIM:

• Enable biometric authentication (fingerprint or Face ID) on your banking apps—this adds a crucial second layer of protection
• Use app-based 2FA (Google Authenticator or Authy) instead of SMS codes when possible, as SMS can still be vulnerable to sophisticated SIM swap attacks
• Set up remote device tracking (Find My iPhone or Find My Device) before you travel, so you can lock or wipe your device if it's stolen
• Choose a reliable eSIM provider like Bitjoy with instant activation (2-5 minutes), so you can quickly restore connectivity on a replacement device without waiting days for a physical SIM card

Real scenario: Imagine your phone is pickpocketed in Barcelona. With a physical SIM, the thief could pop it into another phone and potentially intercept your bank's SMS codes within minutes. With an eSIM, you can immediately disable it remotely, buy a replacement phone, activate a new Bitjoy eSIM in under 5 minutes, and secure your accounts—all while the thief is stuck with a locked device they can't use.

Is an eSIM safe if the phone gets stolen?

One of the major advantages of eSIM is its superior physical security compared to traditional SIM cards. If a phone is stolen, the eSIM cannot be physically removed, and disabling or replacing it usually requires authentication. This makes it easier to track the device, as phones with active eSIMs are typically harder to resell.

Is an eSIM safe from SIM swapping?

Although eSIMs cannot be physically removed, SIM swapping can still occur. Hackers may impersonate a user’s identity to request a new SIM activation, leading to risks similar to those with physical SIM cards. The success of such attacks largely depends on the authentication methods used by the service provider.

Can an eSIM be tracked?

Yes, an eSIM can be tracked—but the good news is that tracking works the same way as with physical SIM cards, and you have several ways to protect your privacy.

How eSIM tracking works: Your mobile carrier can see which cell towers your device connects to, giving them approximate location data. The key identifier they use is your device's IMEI (International Mobile Equipment Identity) number, not the SIM itself—whether it's physical or embedded. This means eSIMs don't introduce any new tracking vulnerabilities compared to traditional SIMs.

Practical privacy protection for travelers:

Disable unnecessary location services: Go to Settings > Privacy > Location Services (iPhone) or Settings > Location (Android). Turn off location access for apps that don't truly need it. Keep it enabled only for essentials like Google Maps, Uber, or translation apps you'll actually use while traveling.

Use a VPN on public networks: When connecting to WiFi at airports, hotels, or cafes, use a VPN to encrypt your internet traffic and mask your IP address. This prevents third parties from tracking your online activity. Some eSIM providers like Saily now include built-in VPN protection, though Bitjoy users can add any VPN app they prefer.

Turn off WiFi and Bluetooth when not needed: These signals can be used for location tracking even when you're not actively using them. Disable them in crowded tourist areas or when you don't need connectivity.

Use Airplane Mode strategically: When you don't need mobile data—like when you're sleeping at your hotel or have access to trusted WiFi—enable Airplane Mode to completely disconnect from cellular networks.

Good news for Bitjoy users: Because Bitjoy eSIMs connect through major local networks in 190+ countries, you have the same network-level privacy protections as local residents. This is often more private than using your home carrier's international roaming, which logs all your activity through your home network and can be more easily monitored across borders.

Can an eSIM be cloned?

The possibility of cloning an eSIM is extremely low due to the lack of physical access. Remote cloning is also not feasible, as eSIM profiles are tightly controlled and managed by the service providers.

Can an eSIM be hacked?

eSIM technology incorporates multiple security measures, reducing the risk of hacking compared to physical SIM cards. However, no device is completely secure. Users should remain cautious of suspicious links and unverified apps to protect their personal information.

Is an eSIM safe from port-out scams?

eSIM offers a higher level of security against port-out attacks compared to removable SIM cards. Although it is more difficult for attackers to transfer the phone number, users still need to remain vigilant to protect themselves from these threats.

Is an eSIM safer than a physical SIM card?

As more smartphone manufacturers integrate eSIM technology into their devices, it’s important to understand the security differences between eSIM and traditional SIM cards. Below is an analysis of the key security aspects of both types of SIMs.

eSIM security vs. physical SIM: what’s more vulnerable?

Here is a comparison of the security aspects between eSIM and physical SIM:

• SIM hacking: eSIMs can be targeted through malware and phishing attacks, but they are generally less vulnerable than traditional SIM cards.

• SIM cloning: eSIMs are much less likely to be cloned since they are embedded in the device, whereas physical SIMs can be copied if there is physical access.

• SIM swapping: Both types of SIMs are susceptible to swapping attacks, depending largely on the service provider’s security measures.

• Tracking: eSIMs and physical SIMs have similar tracking capabilities, with no significant difference in how they can be monitored.

The verdict: which option protects your data better?

Overall, eSIMs are more secure than physical SIM cards, especially in terms of physical security and resistance to cloning. Because eSIMs cannot be easily removed or tampered with like traditional SIMs, many security risks are significantly reduced. However, neither type of SIM is completely immune to threats such as hacking, tracking, and SIM swapping. Therefore, users should maintain good cybersecurity practices to protect their personal information.

Bottom line for travelers: eSIMs win on nearly every security measure, especially for physical protection and emergency situations abroad. With providers like Bitjoy offering 2-5 minute activation and a 5-day money-back guarantee, you can test the security benefits risk-free.

Are travel eSIMs safe for international use?

With the growing use of eSIMs, they have become a popular choice for travelers. eSIMs allow you to connect securely to mobile networks, helping you avoid unreliable free WiFi connections.

Common security concerns when using eSIMs abroad

When using eSIMs while traveling, users often worry about security issues such as network attacks and eSIM profile management. Although eSIMs are considered secure, users still need to exercise caution when accessing public internet and protect their personal information.

How to make an eSIM even more secure

Protecting your eSIM is crucial, especially when you’re on the move. Here are some measures to enhance the security of your eSIM:

Enable screen lock and biometric authentication

Activating screen lock and biometric authentication is an effective way to secure your device. This helps prevent others from accessing your personal information and eSIM profiles if your device is lost or stolen. Make sure to set a strong password and use authentication methods like fingerprint or facial recognition.

Avoid public Wi-Fi and unknown QR code sources

Avoid using public Wi-Fi networks and scanning QR codes from unknown sources. Public Wi-Fi is often insecure and can be a target for hackers. If you must use public Wi-Fi, consider using a VPN to protect your connection. Also, only scan QR codes from trusted sources to minimize security risks.

Travel-specific eSIM security tips

When you're traveling internationally, eSIM security takes on extra importance. Here's how to protect yourself in common travel situations:

At the airport

The risk: Scammers set up fake "Free WiFi" QR codes or offer "local SIM card" deals that are actually phishing attempts.

Stay safe: Only scan the official eSIM QR code provided directly by your provider (Bitjoy sends it via email or through their official app). Never scan random QR codes from posters or flyers, even if they claim to offer free internet. Once your Bitjoy eSIM activates (takes 2-5 minutes), use your own secure data connection instead of public airport WiFi for banking or email.

During border crossings

The risk: Some countries require you to unlock your phone for customs inspection, potentially exposing sensitive data.

Stay safe: Before traveling to high-risk destinations, temporarily remove sensitive apps (banking, work email with confidential data). You can reinstall them after clearing customs. Your eSIM profile remains secure since it cannot be accessed without your device passcode and biometric authentication. Consider enabling "Guided Access" (iPhone) or "Screen Pinning" (Android) to limit what inspectors can see if you must unlock your device.

When working from cafes (digital nomads)

The risk: Public workspaces often have compromised WiFi networks where hackers can intercept your data.

Stay safe: Use your Bitjoy eSIM data connection instead of cafe WiFi for all sensitive work. If you need to share your connection, enable your device's hotspot feature with a strong password (at least 12 characters mixing letters, numbers, and symbols). This prevents others from piggybacking your connection. At just $4.50+ for travel plans, the cost of using your own secure data is often lower than the risk of identity theft from public WiFi.

Hotel WiFi: avoid it

The risk: Hotel WiFi networks are frequently compromised and are prime targets for hackers looking to steal guest data.

Stay safe: Never use hotel WiFi for banking, shopping, or accessing work accounts. Instead, rely on your Bitjoy eSIM's secure mobile data. With competitive pricing and plans ranging from 1GB to 20GB+, you can stay protected throughout your entire trip without breaking your budget.

Emergency: your phone is stolen while traveling

The scenario: Your phone is pickpocketed in Rome, stolen from a beach in Bali, or left in a taxi in Tokyo.

Immediate action plan (first 10 minutes):

1. Use Find My Device on a friend's phone or hotel computer
2. Put device in Lost Mode (locks phone and displays your contact message)
3. Contact Bitjoy support via WhatsApp or email to suspend your eSIM profile
4. Change critical passwords for email, banking, and social media from a secure device
5. File a police report for insurance purposes

Getting back online (next hour):

1. Purchase or borrow a replacement device
2. Buy a new Bitjoy eSIM for your destination (covered by 5-day refund guarantee if you have issues)
3. Scan the QR code and activate—you'll be back online in 2-5 minutes

• Your device's IMEI number (dial *#06#)
• Screenshots of your eSIM QR code (stored in encrypted cloud storage)
• Your carrier account login credentials (use a password manager)
• Emergency contact numbers for your bank and credit cards

This way, if your phone is lost or stolen, you can quickly access everything you need to secure your accounts and restore connectivity.

FAQ about eSIM safety

Here are some frequently asked questions about the security of eSIM technology to help you better understand its reliability and safety when in use.

Can eSIM technology be trusted?

eSIM technology can be fully trusted thanks to its advanced security features. Compared to traditional SIM cards, eSIMs are harder to steal or tamper with because they use advanced encryption to protect data. Additionally, eSIM activation is tightly managed by carriers, which helps minimize the risk of cloning.

However, eSIMs are not completely immune to social engineering attacks. Therefore, users should maintain good cybersecurity habits to ensure their personal safety.

Are free eSIMs less secure than paid ones?

Free eSIMs may be less secure compared to paid eSIM services. Paid providers often invest more in security measures and customer support, whereas free eSIMs might not offer the same level of protection. Users should exercise caution and choose reputable eSIM providers to ensure their safety.

What happens to my eSIM if I reset my phone?

When you perform a factory reset on your phone, your eSIM usually will not be deleted. However, you may need to reactivate the eSIM afterward. To ensure uninterrupted use, be sure to save your activation information, such as the QR code or account details from your service provider.

How do I enable SIM lock on my eSIM for extra security?

SIM lock (also called SIM PIN) adds a PIN code that must be entered every time your device restarts, preventing unauthorized eSIM use even if someone bypasses your device lock.

To enable on iPhone: Settings > Cellular > SIM PIN > toggle on, enter a 4-8 digit PIN you'll remember

To enable on Android: Settings > Security > SIM card lock > toggle Lock SIM card, create a PIN

Important: If you enter the wrong PIN three times, your eSIM will lock and require a PUK code from your carrier to unlock. Contact Bitjoy support if this happens.

What should I do if I suspect a SIM swap attack on my eSIM?

Warning signs:

• Sudden loss of service even though your phone shows signal bars
• Cannot make calls or receive SMS
• Notifications about password changes you didn't request
• Unexpected 2FA codes arriving for accounts you're not accessing

Immediate actions:

1. Contact your eSIM provider immediately (Bitjoy: 24/7 WhatsApp support)
2. Request they verify your identity and freeze any eSIM changes
3. Change passwords for all critical accounts from a secure computer (not your phone)
4. Enable additional security verification with your carrier
5. File a police report (needed for identity theft protection)

Can I use multiple eSIMs to improve security?

Yes! Many modern phones support multiple eSIM profiles, which can enhance your security:

Travel setup: Keep your home carrier eSIM for important calls/SMS (bank notifications, 2FA) while using a Bitjoy travel eSIM for data. This way, if your travel eSIM has issues, you still have your home number for critical communications.

Backup option: Install a second eSIM from a different provider as emergency backup. If your primary connection fails, you can switch profiles instantly without finding a local SIM shop.

Privacy separation: Use one eSIM for work and another for personal use, keeping your professional and private activities separated.

Note: Most phones can store 5-10 eSIM profiles but only use 1-2 simultaneously. Check your device's specifications.

Does travel insurance cover eSIM-related security issues?

It depends on your policy, but many travel insurance plans now cover:

• Device theft: Replacement cost of your phone (which includes the embedded eSIM)
• Unauthorized charges: If a SIM swap attack leads to fraudulent transactions
• Identity theft assistance: Legal support and credit monitoring

What's typically NOT covered:

• Cost of replacement eSIM data plans (usually only $4.50-$20)
• Convenience costs like taxi rides to find WiFi
• Opportunity cost of being disconnected

Pro tip: Bitjoy's 5-day money-back guarantee means if you experience any security issues with a new eSIM purchase, you'll get a full refund—providing a safety net even without insurance.

Are free eSIMs less secure than paid services like Bitjoy?

Generally, yes—free eSIM services may have weaker security:

Potential risks of free eSIMs:

• Less investment in security infrastructure
