- More secure, as it cannot be physically removed or duplicated
- Ideal for frequent travelers who need to switch carriers easily
Since eSIM is an officially supported feature, it provides a reliable and future-proof solution for mobile connectivity.
What Is R-SIM?
R-SIM is a third-party unlocking chip that allows users to bypass carrier restrictions on locked devices, mainly iPhones. It is placed between a traditional SIM card and the SIM tray to enable unauthorized network access.
Disadvantages of R-SIM:
- Requires a physical SIM card
- Not an official or permanent unlocking solution
- May stop working after software updates
