eSIM is the digital-first evolution of the SIM card. Embedded directly into your device's motherboard, it allows you to activate cellular service instantly—without physical swapping or waiting for mail.
It's a tiny chip (MFF2) soldered inside your phone. It's 3x smaller than a Nano-SIM, freeing up space for larger batteries and better waterproofing.
Profiles are downloaded over-the-air (OTA). You can store up to 8+ different plans on a single chip and toggle between them in seconds.
eSIM cannot be physically removed if your device is stolen, making it significantly harder for thieves to disconnect your phone from tracking services.
Transitioning to digital SIMs is easier than you think.

Within seconds of purchase, an encrypted digital profile is sent to your email as a QR code.
Open your phone settings, scan the QR, and the internal chip configures itself to the local network automatically.

Optional Support"I was confused about SIM cards until I discovered eSIM. The digital approach eliminated the hassle of physical cards and made my travel experience much smoother."
Yes, absolutely. This is technically known as Dual SIM Dual Standby (DSDS). Most modern smartphones allow you to keep your primary physical SIM active for calls and SMS while using an eSIM exclusively for high-speed, low-cost travel data. You can choose which SIM to use for data in your phone's cellular settings.
A factory reset typically targets system settings and local storage. During the reset process, most devices (iPhone and Android) will explicitly ask: "Erase eSIMs or Keep eSIMs?"
Generally, yes. For security and fraud prevention, an eSIM profile is cryptographically bound to your device's unique EID (Embedded Identity Document) number. This prevents unauthorized cloning of your number. However, many premium carriers now offer a "Transfer" feature within their apps to move profiles between compatible devices.
Yes, the speed is identical. An eSIM uses the exact same cellular modem and antennas as a physical SIM. Your data speed depends on the local carrier's network (4G/LTE or 5G) and your location. In many cases, eSIMs from premium providers like MySecondLine even offer Tier-1 priority, ensuring you get the fastest available bandwidth even in crowded areas.
It depends on the plan, but generally, no. Most travel eSIM QR codes are designed for one-time activation. If you delete the eSIM profile from your phone settings, the "security token" is usually invalidated to prevent fraud. We highly recommend never deleting your eSIM until you have completely finished using the data plan or it has expired. If you are having connection issues, it is better to toggle the "Turn On This Line" switch off and on instead of deleting it.
Check your device model and carrier compatibility. Most iPhones from iPhone XS and later support eSIM, as do many Android devices from Samsung, Google Pixel, and others released after 2018. You can also check your phone's settings under "Cellular" or "Network & Internet" to see if eSIM options are available. Visit our compatibility checker for your specific device.
Yes, many modern devices support multiple eSIMs. iPhone models can typically store 8+ eSIM profiles, while Android devices vary by manufacturer. However, you can usually only have 2 lines active simultaneously (one physical SIM + one eSIM, or two eSIMs). You can switch between profiles instantly through your device settings without needing to reinstall.
Yes, eSIMs offer enhanced security features. Since they cannot be physically removed, eSIMs are theft-resistant and harder to clone. Digital profiles use encryption and secure over-the-air downloads. Additionally, eSIMs support remote management features like instant deactivation if your device is lost or stolen, providing better protection than traditional SIM cards.
Yes, you need an internet connection to activate an eSIM. The activation process requires downloading the carrier profile over-the-air. Make sure you have Wi-Fi or cellular data available when setting up your eSIM. Once activated, you can use the eSIM data plan for connectivity.
Yes, you can switch between eSIM profiles easily. Modern devices allow you to have multiple eSIM profiles installed and switch between them through your device settings. You can enable/disable specific profiles without needing to delete and reinstall them, making it convenient to switch between different data plans or carriers.
eSIM profiles are typically tied to the device. Most carriers don't allow transferring eSIM profiles between different devices due to security and anti-fraud measures. You'll need to purchase a new eSIM for your new device. However, some carriers offer transfer tools for specific device models within their ecosystem.
