Apple could expand its eSIM-only strategy to Europe with the upcoming iPhone 18 series, according to a recent report. The move would involve removing the physical SIM card tray from European models, potentially freeing up internal space for a slightly larger battery.
The company first introduced an eSIM-only iPhone model in the United States with the launch of the iPhone 14 series in 2022. Since then, Apple has gradually expanded eSIM-only variants to select international markets.
eSIM Shift
A report by Techmaniacs suggests that Apple plans to launch eSIM-only iPhone 18 models in Europe. If implemented, this would mark a significant step in Apple’s global transition away from physical SIM cards.
Currently, most international iPhone models continue to offer a physical SIM slot alongside eSIM support. However, recent iPhone 17 models in select countries, including Japan, Canada and the UAE, reportedly do not include a physical SIM tray.
The iPhone 18 lineup could extend this approach to the European market.
Battery
One of the main motivations behind removing the SIM tray is improved internal space management. Eliminating the physical SIM mechanism can create additional room inside the device.
This extra space may allow Apple to install a slightly larger battery. The global variant of the iPhone 18 Pro Max is rumoured to feature a battery capacity between 5,100mAh and 5,200mAh. That would represent roughly a five percent increase compared to the battery in the iPhone 17 Pro Max.
| Model | Expected Battery |
|---|---|
| iPhone 17 Pro Max | Approx. 4,900mAh–5,000mAh |
| iPhone 18 Pro Max | Approx. 5,100mAh–5,200mAh |
While the increase may appear modest, even incremental gains can contribute to improved battery life when combined with processor efficiency improvements.
User Impact
Switching to eSIM-only devices means users must activate mobile plans digitally through their carrier instead of inserting a physical SIM card.
This approach offers certain advantages:
- Instant activation and deactivation
- Easier switching between mobile plans
- Reduced need for physical components
However, it may present challenges for users who frequently swap SIM cards between devices. In some regions, issuing a new eSIM may also involve additional charges from telecom providers.
Travelers who rely on physical prepaid SIM cards could face adjustments, depending on local carrier support for eSIM activation.
Global Rollout
Apple’s transition away from physical SIM cards began in the United States in 2022 with the iPhone 14 lineup. Outside the US, devices continued to include both SIM options.
In 2025, the company reportedly expanded eSIM-only variants to additional countries. The potential inclusion of Europe in the iPhone 18 generation would represent a broader international shift.
The move aligns with Apple’s long-term hardware strategy of reducing physical ports and components to improve durability, space efficiency and internal optimisation.
Launch Timeline
The iPhone 18 Pro and iPhone 18 Pro Max are expected to be announced in September, potentially alongside the rumoured iPhone Fold. The standard iPhone 18 may arrive later, possibly in a separate launch window next year along with the iPhone Air.
Pricing is expected to remain similar to the iPhone 17 series, although official confirmation is yet to come.
Market Context
The smartphone industry has gradually embraced eSIM technology, though adoption varies by region. While many European carriers support eSIM activation, the transition may require coordination with telecom operators to ensure smooth onboarding.
If Apple proceeds with removing the SIM tray in Europe, it would further standardise its global hardware design and potentially improve battery capacity in its flagship models.
The iPhone 18 series could mark another step in Apple’s shift toward fully digital connectivity. By removing the SIM card slot in Europe, the company may gain additional internal space for a modest battery increase. While eSIM offers convenience and streamlined hardware design, the transition may require adjustment for users accustomed to physical SIM cards. Official details are expected closer to launch.
