I switched to eSIM in 2025, and I am full of regret
SIM cards, the small slips of plastic that have held your mobile subscriber information since time immemorial, are on the verge of extinction. In an effort to save space for other components, device makers are finally dropping the SIM slot, and Google is the latest to move to embedded SIMs with the Pixel 10 series. After long avoiding eSIM, I had no choice but to take the plunge when the time came to review Google's new phones. And boy, do I regret it.
The journey to eSIMSIM cards have existed in some form since the '90s. Back then, they were credit card-sized chunks of plastic that occupied a lot of space inside the clunky phones of the era. They slimmed down over time, going through the miniSIM, microSIM, and finally nanoSIM eras. A modern nanoSIM is about the size of your pinky nail, but space is at a premium inside smartphones. Enter, eSIM.
The eSIM standard was introduced in 2016, slowly gaining support as a secondary option in smartphones. Rather than holding your phone number on a removable card, an eSIM is a programmable, non-removable component soldered to the circuit board. This allows you to store multiple SIMs and swap between them in software, and no one can swipe your SIM card from the phone. They also take up half as much space compared to a removable card, which is why OEMs have begun dropping the physical slot.
