Apple’s upcoming iPhone 18 series could arrive without a physical SIM card slot in European markets, according to a recent report circulating in the supply chain ecosystem. The move is said to align with Apple’s broader push toward eSIM technology, a transition that began with US models in recent years.

If implemented, the change would mark a significant shift for European customers, where physical SIM trays have remained standard despite the growing availability of eSIM support among major carriers.

Internal Space to Be Used for Battery Enhancement

Sources cited in the report suggest that removing the SIM card slot would free up a small but valuable amount of internal space. Apple is reportedly planning to use this reclaimed area to accommodate a slightly larger battery.

While the increase in battery capacity may not be dramatic, even marginal improvements can enhance real-world battery life, especially when paired with more power-efficient chipsets expected in the iPhone 18 lineup. Improved thermal management and component reconfiguration could also contribute to better overall performance.

Following a Design Philosophy of Minimalism

Apple has consistently pursued a minimalist hardware approach. The removal of the headphone jack, the shift toward MagSafe, and the gradual reduction of physical ports reflect the company’s long-term strategy of simplifying device architecture.

Transitioning fully to eSIM in Europe would further streamline the iPhone’s internal design. Fewer physical components could also improve durability by reducing potential entry points for dust and moisture.

European Market Readiness for eSIM

In recent years, European telecom operators have expanded eSIM support across prepaid and postpaid plans. Most major carriers now allow users to activate eSIM digitally without visiting retail outlets.

However, adoption varies by country, and some smaller carriers still rely heavily on traditional SIM infrastructure. Apple’s move, if confirmed, could accelerate wider eSIM implementation across the region.

Expected Alongside Other iPhone 18 Upgrades

The iPhone 18 series is also expected to introduce improvements in processing power, camera capabilities, and display efficiency. Reports hint at next-generation chipsets built on more advanced manufacturing processes, potentially offering better performance-per-watt ratios.

Combined with a slightly larger battery, users could see measurable gains in endurance compared to previous models.

Launch Timeline and Availability

Apple typically unveils its flagship iPhone lineup in September, and the iPhone 18 series is widely expected to follow that schedule in 2026. If the report proves accurate, European buyers may need to prepare for an eSIM-only experience similar to what US customers have already adopted.

Apple has not officially confirmed any changes regarding SIM card configurations, and final specifications will only be known at launch.
