eSIM in 2025, Full of Regret

|

In his recent Ars Technica article, senior technology writer Ryan Whitwam explains why switching to eSIMs for his new Pixel 10 series review phone has been more headache than help. He remembers the simple days of popping a physical SIM card from one phone to another, and writes with genuine frustration about how that convenience has vanished as phone makers ditch physical SIM slots in favor of eSIMs.

Below is the concise key highlights of Whitwam’s article, summarized with the assistance of AI tools:

  • The Journey to eSIM: Whitwam traces the SIM card’s evolution from the big plastic cards of the ’90s to tiny nano-SIMs, and now to embedded SIMs (eSIMs) soldered into modern phones. eSIMs were introduced years ago and gradually supported as a digital alternative to physical cards. Phone makers like Apple already went eSIM-only, and now Google followed suit with the Pixel 10 series in the U.S., eliminating the physical slot entirely — all in the name of saving space inside devices.
  • Support Isn’t Great: What really irks Whitwam isn’t the idea of eSIMs, it’s how messy things can get when something goes wrong. In his months of using eSIM, he’s had two transfers fail, leaving his phone number in limbo. Built-in Android tools have improved, but carriers still rely on SMS for identity verification. If your eSIM is stuck and you can’t get texts, you can’t authenticate — and you’re trapped. On one occasion this meant an hour in a carrier store just to get back online — a far cry from the seconds it used to take to swap a physical SIM.
  • eSIM maybe not such a good idea yet: Whitwam points out that a phone number isn’t just for calls — it’s used for authentication everywhere: banking, apps, accounts, and more. When an eSIM transfer glitches, you’re not just off the network for a few minutes — you could lose access to major parts of your digital life. Physical SIMs almost never fail and move between phones instantly, whereas eSIMs can become a software-and-support nightmare.

In conclusion, Whitwam’s experience suggests that while eSIMs might be the future, the present still feels rough around the edges, especially when carriers and authentication systems haven’t adapted to make the switch seamless for everyday users.
