Recently we have told you about the Russian innovation company Intersoft Eurasia, which develops a dosimeter-radiometer module for Project Ara smartphone. However, this is not the only invention by this company. Vladimir Elin, CEO of Intersoft Eurasia, also shared with us the concept of multi-SIM module for ARA phone.
Smartphones with two SIM card slots are quite widespread. Such phones are very useful if you have two phone numbers and often use them alternately. But if a mobile user wants to have three or more numbers, certain inconveniences start to emerge: changing SIMs manually, which may take some time; losing a SIM card if it’s not in the phone; etc. So the Russian company Intersoft Eurasia came up with an idea of the device that could store several SIM cards.
Multi Dynamic SIM device
In summer 2013 Intersoft Eurasia patented Multi Dynamic SIM for hosting several SIMs, which can function simultaneously. It resembles an ordinary credit card of similar length and width, but slightly thicker (2.5 to 3 mm). It has nine slots for various SIMs (standard, mini, micro and nano) and can be carried in a wallet or pocket with nine slots for various SIMs (standard, mini, micro and nano). As a result, the device enables a single smartphone to use up to nine numbers.
The processor integrated into the Multi Dynamic SIM manages operation of hosted SIMs. It connects them through SMART Bluetooth or NFC channels to the virtual SIM installed in a smartphone, a tablet, etc. The user is able to switch between SIMs via special software installed on the phone. The software may be configured in any way. For example, it may select the cheapest communication channel of the highest quality automatically, taking into account traffic price subject to seasonal or day/night discounts, partner programs of operators, etc.
Multi-SIM module for Project Ara
The so-called multi-SIM module for Ara smartphone doesn’t contain various slots for SIM cards as you might think. This module has a microchip called UPRA (Unified Personal Resource Authorizer), which is able to store and use data from various mobile operators (up to 512 phone numbers). It can keep a variety of user profiles, including all keys, a phone number, service access keys (i.e. full SIM card content). It also allows for secure storage of Wi-Fi network and IP telephony keys, as well as keys to access buildings or parking lots. Moreover, it guarantees security, which is of more importance to customers. Such microchip can receive and transmit data wirelessly and is also known as “multi-functional mobile communication subscriber identification unit”.
Once the user subscribes to a tariff plan, he needs to download data from operator into the multi-SIM module. If the user buys another tariff plan from another operator, he just adds it to the same module and so on. So this module will contain all the info from all mobile operators the customer is subscribed to. There will be no dependence on SIM-cards as we see it today. The technology seems futuristic but for sure it will have a huge demand. Promising technologies are implemented rapidly by tech companies.
