What Is an eSIM?
A built-in SIM chip found in smartphones, smartwatches, and other gadgets is known as an embedded SIM, or eSIM. eSIMs do not need to be physically swapped, in contrast to conventional SIM cards. Alternatively, a mobile carrier can remotely activate and reprogramme them.
Key Features of eSIM
- No physical card required – eSIM is embedded inside the device.
- Supports multiple networks – Users can switch between carriers without changing SIM cards.
- More secure – Since it cannot be removed, the risk of theft or loss is reduced.
- Saves space in devices – Smartphones with eSIM do not need a SIM tray, making them more compact.
What Is an R-SIM?
A unique kind of SIM card called R-SIM (Roaming SIM) is used to get around network limits on iPhones and other gadgets. To get over carrier locks, a tiny chip is positioned on top of a conventional SIM card.
Key Features of R-SIM
- Used for carrier unlocking – Helps users switch networks on carrier-locked phones.
- Works with physical SIM cards – Unlike eSIM, R-SIM requires a traditional SIM.
