iPhone three SIM-cards may become a reality

If there’s one company in the world that completely ignores the smartphones that support two SIM cards, it’s Apple. However, in iPhone 8 the company intends to implement a number of innovative technologies, so it is likely that the next generation of smartphones Apple will be able to work with two and even three SIM-cards.

While Apple does not reveal the functionality of the iPhone 8, but there are a number of patents confirming the company’s interest in phones that supports two SIM cards, and without doubt the next iPhone is a major contender for this technology. Here you can enable and Apple Watch.

If this next iPhone does not have to be equipped with two physical slots. Apple has long hoped to replace the conventional SIM card on eSIM that will improve the moisture resistance of the device and to allocate additional space inside the case. All depends on the position of mobile operators.

This week, the Bureau of patents and trademarks U.S. published patent application Apple, confirming the company’s interest in eSIM. Document 20170099285 describes “Methods and devices to support a Global Platform for embedded UICC (eUICC)”.

“Most wireless devices (e.g., smartphones) is configured to use a universal card integrated circuit (UICC), which provide access to services wireless network. The UICC is typically a small, removable card (e.g. subscriber identity module (SIM)), which is placed in the wireless device. In most cases, each associated with one of the UICC by the Issuer, such as a mobile network operator – which manages and distributes the UICC. A popular standard, known as GlobalPlatform, supported by most of mobile operators and provides secure and interoperable management of UICC.

In later implementations, a non-removable UICC, referred to here as embedded UICC (eUICC), embedded on system Board wireless devices. These eUICC differ from traditional removable UICC being non-removable, soldered directly to motherboards wireless devices. For the transition from the UICC to the eUICC need to rewrite the software of the UICC with the addition of new functions and/or applications to provide hardware changes. It is necessary for a transparent transition from the UICC to the eUICC”, the application says Apple

Apple is looking for a simple way to transition from physical “love” to electronic. Of course, this does not mean that the iPhone 8 will support two or three SIM-cards, but confirms the company’s interest in such developments.

This is also evidenced by the patent application 20170094628 from March this year, in which Apple describes a mobile device with two or more SIM cards. Company tells how to simplify the introduction of multiple SIM smartphones.

“Although these wireless communication devices provide flexible access to various services and multiple wireless networks, the internal architecture of devices with support for multiple UICC / SIM typically includes parallel hardware and software, so that each UICC / SIM acting independently. Internally, the architecture is simple, however, the independent operation of the two UICC / SIM card (and associated hardware / software) in the wireless communication device may be inefficient because each system can duplicate the various functions used to manage network connections. Thus, there is a need for solutions that enable communication hardware and software in devices with multiple SIM”.

It is noteworthy that Apple is considering the option of simultaneous use of physical and electronic SIM card, so iPhone 8 can still only have one slot, but at the same time to support multiple connections thanks to the eSIM.

In the patent application also describes a scenario in which two devices, each of which supports at least one SIM / eSIM to communicate through wireless protocols such as Wi-Fi or Bluetooth. Given that the Apple Watch Series 3 can obtain the module LTE, the patent may indicate how to construct the work of LTE in future “smart” hours and iPhone.
