Both SIM cards (Subscriber Identity Modules) and eSIMs (Embedded SIMs) are used to store and activate mobile phone subscriptions, but there are some key differences between the two:

  • Physical vs. digital: A SIM card is a physical card that is inserted into your phone, while an eSIM is a digital version of a SIM that is built into your phone.

  • Removable vs. non-removable: Because a SIM card is a physical card, it can be removed from your phone and replaced with another SIM card if needed. An eSIM, on the other hand, is non-removable and cannot be easily swapped out.

  • Compatibility: SIM cards are compatible with most phones, while eSIMs are only compatible with certain models of phones.

  • Activation: SIM cards can be activated by inserting them into a phone and following the prompts on the screen. eSIMs can be activated remotely, typically by scanning a QR code or entering a code provided by the mobile service provider.

Ultimately, which is better depends on your individual needs and preferences. SIM cards are a tried-and-true option that are widely compatible, while eSIMs offer the convenience of remote activation and the ability to switch between multiple mobile service providers without having to physically swap out SIM cards.
