The mobile industry is poised to undergo a significant transformation in the next two years, with the impending shift to integrated SIMs, or iSIMs, new research has claimed. 

A new study from Juniper Research predicts a huge increase in the global number of iSIMs installed in connected devices, jumping from 800,000 in 2024 to over 10 million by 2026. 

The release of GSMA's SGP.41/42 specifications, expected by the end of 2025 year, will drive the anticipated 1,200+ percent growth. These guidelines will standardize and streamline iSIM-enabled device rollout.

Anticipated surge in connections

An iSIM (also known as the iUICC - Integrated Universal Integrated Circuit Card) is based on the eSIM (embedded SIM) form factor and integrated in the device’s processor, effectively removing the need for a separate SIM module. The iSIM's integration looks likely to propel us towards an era where the traditional SIM card will become obsolete and networks will preload plans onto devices.

The GSMA's SGP.41/42 specifications establish the framework for In-factory Profile Provisioning (IFPP) capabilities. IFPP enables the upload of iSIM profiles onto a device during production, enabling the shipment of devices with pre-configured cellular connectivity to the desired network. 

Juniper’s report points out that “Despite the increased readiness, it is important to note that there is no industry-wide standard for iSIM technology as of yet. Without a standard, manufacturers will not be willing to risk launching a solution that is not compliant with an official standard.” 

Elisha Sudlow-Poole, the author of Juniper Research’s report adds, “eSIM vendors must ensure that they provide standard-agnostic platforms that are flexible to upcoming form factors, standards and use-case demands. Additionally, eSIM vendors must develop trusted partnerships with manufacturers to ensure adoption of iSIM connectivity services once it becomes demanded in the market.”

Juniper's study expects to see the number of iSIM connections surge to 210 million worldwide by 2028, thanks to adoption opportunities in scenarios such as smart energy meters and remote logistics, where there's a need for power-conscious and small form factor devices.

You can read through our iPad Pro 13-inch (2024) review to find out just how impressed we are with Apple's latest premium-level tablet – and a newly published teardown video reveals some of the under-the-hood design changes in this model.

If you remember back to the launch of the device, Apple mentioned incorporating graphite sheets into its main housing, and using copper in the Apple logo to improve thermal performance over the previous 2022 model by nearly 20%.

The new teardown video from Phone Repair Guru (via MacRumors) includes a close up look at those alterations, as well as showing the internal shifts needed to get the front camera and Face ID components over to the right side (as you look at the screen of the iPad Pro in portrait mode).

We also see changes to the array of magnets built into the tablet: these have been moved around quite a bit to add support for the new Apple Pencil Pro and the new Magic Keyboard that were launched at the same time as the new iPad Pros.

Tear it down

The video runs to nearly nine minutes, and we get a close look at the display cables, the four stereo speakers, the front and rear camera modules, and the M4 chip responsible for running everything (complete with Apple logo).

There's also a look at the 10,209 mAh battery, which is split into two sections, and the Apple logo on the back of the tablet, with its added copper – this essentially acts as a heatsink for the M4 chip, ensuring it stays cool enough.

In the video, the tablet is described as having "pretty repairable" innards, and there's an acknowledgement of the "genius" way that Apple has packed everything in here. Remember, this is the thinnest iPad ever, at just 5.1 mm.

We'll no doubt see more teardowns like this appear as time goes on, but we're yet to see the same treatment given to the iPad Air 13-inch (2024). You'll see that both of these new models have jumped right into our best iPads guide.

With summer nearly upon us, temperatures are beginning to rise in the northern hemisphere and most of us know what happens when our smartphones, and other portable electronics, overheat. 

Researchers at the University of Pennsylvania have unveiled an ultra-resistant memory device able to endure extreme temperatures, a development that bodes well not only for smartphones, but for AI devices running in harsh conditions. 

A recently published study in the journal Nature Electronics from Deep Jariwala and Roy Olsson of the University of Pennsylvania, along with their engineering teams, demonstrates a memory technology capable of withstanding temperatures of up to 1,100°F. These high tolerance levels were maintained for over 60 hours, displaying extraordinary stability and reliability.

Megabytes only - for now

The team designed a non-volatile device, meaning it could retain information without an active power source. Unlike traditional silicon-based flash drives that start to fail around 392°F, the team's device used ferroelectric Aluminum Scandium Nitride (AlScN). AlScN has the unique capability of being able to maintain specific electrical states, even at significantly higher temperatures.

The ultra-resistant memory device comprises a metal-insulator-metal configuration with a fine layer of AlScN sandwiched between nickel and platinum electrodes. This unique design was meticulously planned and executed to ensure compatibility with high-temperature silicon carbide logic devices, further enabling the memory device to function alongside high-performance computing systems meant for extreme temperatures. 

“Conventional devices using small silicon transistors have a tough time working in high-temperature environments, a limitation that restricts silicon processors, so, instead, silicon carbide is used,” Deep Jariwala said. 

“While silicon carbide technology is great, it is nowhere close to the processing power of silicon processors, so advanced processing and data-heavy computing such as AI can’t really be done in high-temperature or any harsh environments. The stability of our memory device could allow integration of memory and processing more closely together, enhancing speed, complexity, and efficiency of computing. We call this ‘memory-enhanced compute’ and are working with other teams to set the stage for AI in new environments.” 

Despite the notable progress, the new technology will initially only be available in smaller capacities. Jariwala told us, “Based on the current size of devices and scalability of our fabrication process we can easily attain 10 Megabytes to 100s of Megabytes of storage capacity. Our goal is to commercialize these Megabyte scale chips through our startup company in the near to intermediate future.“
