Virtual SIM card
A brand-new technology in mobile telecommunication
2. Working principle
A core principle of this technology is to multiplex
identification data from SIM cards of different mobile
service providers combined in one virtual SIM-card.
Switching over from one mobile service provider to another is controlled by a special
software which is installed on the virtual SIM card.
Conventional SIM/USIMcard
Virtual SIM-card

3. Physical Medium
A UICC-card that supports SIM/USIM or fits a conventional SIM-card may serve as a
physical medium of the virtual SIM-card. In both cases they require a Java Card standard.
NEIRON.COM LTD
4. Java application
A Java application is a core of the virtual SIM card. It is responsible for algorithms of
switching over between loaded SIM cards of different mobile service providers as well as
for algorithms of loading new SIM-cards from a special server where they are stored.
NEIRON.COM LTD
5. SIM card loading
Loading a SIM card means receiving data for the Subscriber’s authentication in a mobile
network of a new mobile service provider with assignment of a new phone number.
These data may be transmitted as an encoded data package via SMS or Internet.
NEIRON.COM LTD
6. SIM Server
New SIM-cards are loaded from the SIM Server after a Java-application request. Nature
of this request will be defined by an algorithm encoded in the Java App. If it’s necessary
the User can manually load a new SIM card using one of the functions of his/her profile.

7. Numbering Capacity
To provide functioning of this technology the server is required to store data of a
sufficient number of SIM-cards of different mobile service providers. To obtain these SIM
cards it’s necessary to conclude with each mobile service provider the Agreement for
numbering capacity provision and for registration of SIM-cards’ identification data in
mobile networks of service providers.
NEIRON.COM LTD
8. Switching over domestic mobile service providers
One of mobile service providers registered on the virtual SIM card functions as a main
service provider and others are used as stand-by. When a signal of the main provider is
poor the virtual SIM card automatically switches over to one of alternative SIM cards of
stand-by providers, connects to and registers in their network. Thus, the subscriber is
always available. As soon as the main provider signal is strong the virtual SIM-card
switches the subscriber back. Therefore, the subscriber can be available even if the
main provider’s signal is poor or out of coverage at all.

9. Switching over abroad
When the Subscriber is going to another country the SIM Server offers to load a SIM card
of a service provider of the country which the Subscriber travels to. The Subscriber
receives the information on local rates by SMS or through the mobile application. In case
the Subscriber agrees to communicate at local rates he or she receives a new SIM-card
and registers in the new provider’s mobile network as if it is in its home region.
Manual loading of a new SIM from the user’s profile performed beforehand is an alternative way of switching.
NEIRON.COM LTD
10. “Unified Number” issue
To register a new provider in the network the Java Application every time activates a
new SIM-card . Thus, a phone number of the User’s virtual SIM card is also changed.
Friends and colleagues don’t know the User’s number and, therefore, they will be able
neither to call him/her nor identify an incoming call.
NEIRON.COM LTD
11. Solution of the identification problem
The problem of incoming call identification when using a mobile device with the virtual
SIM-card can be solved through updating a contact list of the Subscriber receiving the
call.
Method 1
Method 2
Current information on all phone numbers
is stored in the User’s profile which can be
accessed on-line. The SIM Server
automatically adds new numbers to the
User’s profile. Friends and colleagues of the
Virtual SIM-card holder have to install a
special software on their mobile devices. In
this case new phone numbers will be
automatically loaded to the contact list
through the Internet.
Current information on all numbers is
stored on the SIM Server. Having received a
new number the SIM Server sends recently
updated electronic ID information in the
vcard format to friends and colleagues
subscribed to this updated data. The Vcard
may be sent via SMS/MMS or via Internet.
This method does not require installation of
the special software to friends and
colleagues’ mobile devices.
NEIRON.COM LTD
12. Solving a call completion problem
A problem of reaching the Subscriber using the Virtual
SIM-card can be solved by setting up call forwarding from
all non-active SIM-cards to the active one.
Setting up of call forwarding may be implemented by the SIM Server and does not
overload the Subscriber’s mobile device. A command to set up call forwarding is sent by
the mobile device right after Subscriber’s registration in a new mobile network.
NEIRON.COM LTD
13. Advantages for the Subscriber
The virtual SIM-card technology gives the following opportunities:
1.
2.
3.
To expand considerably a coverage area in a domestic mobile service
provider’s zone due to elimination of coverage areas with low signal
strength (“coverage gaps”);
To save subscribers from expensive voice roaming charges and help
them to communicate at local phone call rates in any country;
To save subscribers from expensive data roaming charges and help
them to transfer data at local rates regardless of country of stay.
NEIRON.COM LTD
14. Convenience
To make it convenient for Subscribers to use telecom services with implementation of
the Virtual SIM-card technology it is required to provide them with:
1.
2.
3.
4.
Convenient replenishment of accounts of mobile service providers
supporting and implementing the virtual SIM-card;
Convenient control of write-offs from the Subscriber’s mobile account.
Convenient system of notification on rates of a current mobile service
provider;
The “one contact” principle to provide consulting and managing of
conflict situations.
NEIRON.COM LTD
15. Replenishment of mobile accounts
The virtual SIM-card technology is aimed at the Subscriber’s usage of telecom services
provided by several mobile service providers. In case of the Prepaid system the
Subscriber will have to maintain settled cash balance on accounts of all providers whose
mobile services he or she uses. It is very inconvenient for the Subscriber.
The solution is creation of a Subscriber’s Unified Account
with post-payment for every call. The Subscriber doesn’t
have to replenish an account of each mobile service
provider but the Unified Account that may be accessed by
all service providers supporting the Virtual SIM-card.
The service provider writes off money from the Unified Account after termination of
every call.
NEIRON.COM LTD
16. Managing write-offs from a mobile user account
A report on write-offs from the Unified Account is a service
additional to the aforesaid account
This report consolidates billing data of all mobile service providers used by the
Subscriber with the virtual SIM-card.
NEIRON.COM LTD
17. Notification on rates
The most convenient option for Subscribers is provision of
unified tariffs or pricing schedules by all mobile service
providers implementing the Virtual SIM-card
However, in some cases it will be impossible. Before loading SIM-card data of a service
provider whose tariff differs from the unified tariff the Subscriber will receive SMS
notification on rates or messages via special mobile application.
Loading of the SIM-card will be performed after User’s confirmation to communicate at
this rate.
NEIRON.COM LTD
18. “One contact” principle
Notwithstanding the fact that the Subscriber uses services of several providers the
Agreement has to be concluded only with the domestic mobile service provider.
Thus, the Subscriber doesn’t have direct contractual
relationship with stand-by providers and all terms of
cooperation shall be regulated by Agreements between
the domestic mobile service provider and Neiron.COM
LTD.
This approach allows implementation of the “one contact” principle engaging the
domestic mobile service provider to manage all Subscriber’s issues which is very
convenient for the Subscriber.
NEIRON.COM LTD
19. Advantage No.1 for the domestic mobile service
provider
Establishment of an exceptional loyalty program that
would ensure operating with better domestic mobile
coverage and prevent subscribers from switching over to
another service provider on psychological grounds.
NEIRON.COM LTD
20. Advantage No. 2 for the domestic mobile service
provider
The Virtual SIM-card technology allows increasing cash
flow due to financial compensation* paid by the stand-by
provider and by the foreign provider after subscriber
switches over to their network.
*a compensation rate is 30-50% of the total tariff amount.
NEIRON.COM LTD
21. Advantage No. 3 for the domestic mobile service
provider
The Virtual SIM-Technology allows luring the most active
and lucrative Subscribers of competitive mobile service
providers.
(These Subscribers are as follows: frequently travelling people, people with higher
demands to stable mobile communication).
NEIRON.COM LTD
22. Motivation of the stand-by provider
When the Subscriber is in areas of poor signal coverage of the domestic provider he or
she automatically switches over to the stand-by provider and uses its mobile network.
Thus, the stand-by mobile service provider receives
revenue from customers serviced by the domestic service
provider.
NEIRON.COM LTD
23. Development stage
At the moment we have developed more
than just a technology. We have created a
mobile device prototype with the virtual
SIM-card.
We also had our prototype successfully tested at Ural branch of
the Open Joint Stock Company Rostelecom, OAO which is
confirmed by the Exam Protocol No. 1 dd. September 09, 2013.
We have also obtained Patent No. 2011141313 for this
technology which is valid in the territory of the Russian
Federation. Obtaining of an international patent is in process.

NEIRON.COM LTD
27. Future development
The architecture of the virtual SIM-card allows storing an electronic digital signature
(EDS) of the Subscriber and create electronic applications supporting the EDS
identification.
These applications may be implemented in numerous spheres starting from state
services, bank services and public transport cards to on-line shops providing one-click
buying.
This sector promises a large number of development
prospects for a new segment of e-commerce monetized
by the commission fee from every transaction.
NEIRON.COM LTD
28. Development prospects
Thus, as a result of development of the Virtual SIM-card it
will be transformed into one universal memory card
including all package of daily tasks required by the
customer: telephone calls, Internet, purchases, payment of
taxes and fines, financial transactions, communication and
training, etc.
NEIRON.COM LTD
29. Development prospects
A final step of the Virtual SIM-card development will be
accumulation of data on Customers’ actions including
geolocation, purchase history by means of e-commerce,
interests and hobbies.
These data will allow creating an individual profile of personal development of each
Customer and form market channels of a next generation where product offerings will
be based on actual and recent information on current needs of the Customer and on
forecasting his or her varying preferences.
NEIRON.COM LTD
30. Project products
