What is eSIM and How Does it Differ from Traditional SIM?
An eSIM (embedded SIM) represents a groundbreaking technological advancement in mobile connectivity, fundamentally transforming how mobile devices connect to cellular networks. Unlike traditional physical SIM cards that require manual insertion and removal, an eSIM is a small microchip permanently integrated directly into your device’s hardware.
Understanding eSIM Technology
The core difference between an eSIM and a traditional SIM lies in its design and functionality. A traditional SIM card is a removable plastic card containing a chip that stores your mobile subscriber identity and network credentials. In contrast, an eSIM is soldered directly onto the device’s motherboard, eliminating the need for a physical card.
Below is a comparison table highlighting the key differences between eSIM and traditional SIM card technology to help clarify their distinct features and functionality.
| Feature | Traditional SIM Card | eSIM (Embedded SIM) |
|---|---|---|
| Physical Form | Removable plastic card | Embedded microchip soldered onto the device |
| Activation & Switching | Requires manual replacement and handling | Switched digitally via software, no manual swapping |
| Profile Management | Single carrier profile per card | Multiple carrier profiles can be stored simultaneously |
| Security | Susceptible to loss or theft | Reduced risk due to integration within the device |
| Device Design | Needs physical slot, limits compactness | Allows more compact device designs |
| Supported Devices | Mainly smartphones, some tablets | Smartphones, smartwatches, tablets, laptops, IoT |
| Set-Up When Travelling | Purchase and insert local SIM manually | Download profile and activate remotely |
