The Slow Death of the SIM Card — and Why the UAE Was an Early Believer

The Slow Death of the SIM Card — and Why the UAE Was an Early Believer

For nearly three decades, the SIM card was the one physical object every mobile phone on Earth had in common: a sliver of plastic you popped out with a paperclip, swapped between devices, and handed over when you switched carriers. That object is disappearing. In its place is the eSIM — a programmable chip soldered permanently into the phone that downloads your carrier's credentials over the air instead of carrying them on a removable card. It sounds like a minor hardware tweak. It's actually rewriting how phones are sold, how carriers compete, and how people travel — and the UAE was one of the first markets in the world to get it.

A standard a decade in the making

The idea of a software-defined SIM isn't new. The GSMA, the industry body that sets global mobile standards, started discussing the concept as early as 2010, aimed initially at machine-to-machine devices like industrial sensors and asset trackers that needed connectivity but had no room — or no sane way — to swap a physical card. The consumer-facing version of the standard didn't arrive until 2016, published in two stages, in March and November of that year.

The first commercial device to actually use it was arguably not a phone at all: Samsung's Gear S2 Classic 3G smartwatch, released in 2016. Apple followed with eSIM support in the Apple Watch Series 3 in 2017, and Google's Pixel 2 is widely credited as the first eSIM-capable smartphone around the same period. Apple didn't bring eSIM to the iPhone line until the iPhone XS, XS Max, and XR in September 2018.

The real inflection point came in September 2022, when Apple's iPhone 14 lineup launched in the United States without a physical SIM tray at all — the first mainstream flagship phone family to go eSIM-only in a major market. Outside the US, Apple kept selling SIM-tray versions of the same phones for years afterward, because plenty of countries — mainland China among them, where eSIM support for consumer phones still isn't permitted — simply weren't ready to make the switch.

The UAE got there early

While much of the world waited for the iPhone XS to force the issue, the UAE's two main carriers moved quickly. According to Gulf News, Etisalat (now rebranded as e&) became the first telecom operator in the Middle East to switch on eSIM support for smartphones, enabling it for the iPhone XS, XS Max, and XR once those devices were running iOS 12.1 in late 2018. Gulf Business reported that du announced its own eSIM rollout around the same window, following an announcement at the GITEX technology show — though Gulf News also noted the rocky reality of early adoption: eSIM wasn't actually available on du's network the moment the iPhone XS first launched in the UAE, forcing some early buyers to wait.

That early stumble aside, the UAE's positioning made sense. It's a market with a huge resident expat population that regularly switches plans or needs multiple numbers, a significant luxury-device buying base that upgrades phones frequently, and two well-capitalized carriers competing hard for both categories. eSIM fit all three pressures at once: it's faster to activate (a QR code instead of a physical card delivery), easier for travelers to add a local or regional data plan without hunting for a SIM shop, and it let carriers skip the logistics of printing and distributing a physical card entirely. Today, both e& and du, along with Virgin Mobile UAE, sell eSIM profiles not just to residents but specifically to tourists landing in Dubai who want local data without opening their phone case.

Why carriers and phone makers actually want this

The physical SIM wasn't just an inconvenience — it was a point of friction carriers hated. Every physical SIM is a manufacturing cost, a retail logistics problem, and a reason a customer has to visit a store or wait for a card to arrive by courier. An eSIM profile is just data: a carrier can provision it instantly, remotely, and reprovision it just as fast if a customer switches plans or operators. For phone makers, removing the SIM tray frees up a sliver of internal volume that can go toward battery capacity or a smaller chassis, and it removes one more port that water or dust could get through.

There's a less customer-friendly motivation too. A phone with no physical SIM slot is harder to resell informally in markets where phones get passed between unofficial resellers and carrier-locked devices get "unlocked" through parallel markets — some of which coincidentally are the same reason parts of the world have been slower to embrace it.

The holdouts and the headaches

eSIM adoption hasn't been a clean global rollout. China still doesn't allow eSIM support for consumer smartphones, which is part of why Apple continued producing dual-SIM-tray iPhone models even after the US went eSIM-only. Switching phones is also still clunkier with eSIM than many users expect: unlike pulling a card out of one phone and into another, moving an eSIM profile typically requires either a carrier-assisted transfer, a fresh QR code, or using both the old and new device at once during setup — something that trips up people replacing a lost or broken phone, who no longer have the simple fallback of pulling a physical card out of a drawer.

Where this goes next

The trajectory is clear even if the finish line keeps moving. Samsung, Google, and Apple have all shipped eSIM-only models in at least one market. The GSMA has continued refining the standard to make multi-profile switching and carrier transfers smoother. And in markets like the UAE, where both major carriers already treat eSIM as a mainstream option rather than a novelty, the physical SIM card's remaining job is increasingly just to serve the markets — and the phones — that haven't caught up yet. For a piece of plastic that's been in every pocket since the 1990s, that's a quiet way to go.
