According to reports, the upcoming iPhone 15 series is expected to lack physical SIM card trays.

This means that users will no longer be able to insert or remove SIM cards manually.

Instead, the iPhone 15 series is expected to rely on embedded SIM technology, also known as eSIM.

eSIM technology allows users to activate their phone's cellular service through software instead of a physical SIM card.

One advantage of eSIM technology is that it allows for greater flexibility when switching between carriers or phone plans.

However, some users may be concerned about the security of their personal information with eSIM technology.

The move towards eSIM technology is in line with Apple's overall strategy of simplifying and streamlining its product designs.

It is important to note that these reports are currently unconfirmed, and Apple has not yet officially announced any details about the iPhone 15 series.
