Rebel SimCard unlocks Network Restrictions on Nokia N82

Solutions Point Limited, UK today introduces its flagship product, Rebel Sim card which can bypass network locks on all mobile phones.

Rebel Sim card has been released today by Solutions Point Limited, UK, they claim this product to be in the line of those smart technological solutions who will bring a revolution in the mobile phone unlocking industry, it would revolutionarise the way people use their mobile phones, by bringing in options which were not possible before.

Rebel Sim card can bypass network locks on almost all phones available in the market till date, and it would also support 95% of upcoming phone models out of the box, without making any changes to Rebel Sim card.

Rebel Sim card is used in parallel to the existing sim card as its only 0.10mm thick, therefore can be inserted along with existing simcard in any of the mobile phones available throughout the world.
It can also be removed easily, without causing any damage to the phone and the phone does not lose its warranty!

Rebel Simcard is the World’s first sim card which is fully compatible with UMTS technologies, which means users will get the same quality of service as they would get with a fully unlocked phone.

Rebel Sim card is transparent to the mobile phone, it does not interrupt in any of the existing features the simcard or the mobile phone has to offer either it be emails, Wifi, Bluetooth, 3G, GPS or any other service, rather it enhances the existing features with its proprietary menu which gives the user a whole lot of control over how Rebel Sim card functions for a particular mobile phone.

Rebel Sim card is backed up by experienced and highly skilled development team along with hundreds of beta testers throughout the world, who test Rebel Sim card on almost any new phone which is released in any part of the world.

Rebel Sim card also has a STK menu, Apart from giving better control to the end user on the Rebel Simcard features, This menu enables it to run high security applications like banking services, transactions etc, moreover it enhances the existing network simcard by adding more features to it, like Value Added Services, Telecom applications, Logos, Ringtones etc. This makes it a one and only choice for MVNO’s who are trying to discover new lands and increase their market share.

However the technology behind bypassing of network locks on a mobile phone looks rather complex and is no way a game of a common man, but by bringing the ease of use and simplicity Rebel Sim card provides to unlock a mobile phone to common people who know nothing about this technology, depicts a fine example, how difficult things can be made so simple by people who are behind such technologies and are working hard and writing new rules of the game

Types of Smart Cards

These Integrated Circuit Cards come in two forms when we categorize them based on the way we use tem, contact and contact-less. The former is easily identified due to its characteristic gold connector plate.

Originally the ISO Standard (7816-2) defined eight contacts, but only 6 are actually used to communicate with the outside world and rest two are marked as RFU (Reserved for future use). The contact-less cards optionally may contain its own power source, however mostly the operating power is provided to the contact-less card by means of an inductive loop that uses low frequency electronic magnetic radiation. The signals needed for communication with the reader devices may be transmitted in a similar way or can use capacitive coupling or even an optical connection (IR).

The Contact card is the most widely used ICC to date largely because of its use as telephone prepayment card. Yes! The SIM card that we you use in our cell phones is just a Smart card without the plastic base. Most contact cards contain only a simple integrated circuit although some also use two chips; the other one is used to perform complex cryptographic computations (which I’ll explain shortly). The chip itself varies considerably between vendors and each takes it own way of programming application for it, but the Java Card™ initiative by Sun has made it a breeze to write Smart Card applications that can be downloaded onto the memory of these cards and can execute on any type of chip which supports the Java Card runtime environment. I’ll come to programming the Smart cards in next article of this series.

Smart Cards

Figure 2

Let us now consider the use of the 6 contacts used by the ICC:

Vcc is the supply voltage that drives the chips and is generally 3 to 5 volts with 10% deviation allowed. It used to be in 5-volt range prior to the recent move towards low power devices to make these cards.

Vss/GND pin is used to provide the substrate or ground reference voltage against which the Vcc potential is measured. It is usually 0 volts.

Reset is the signal line that is used to send the signal to the integrated circuit in order to reset it. This is a complex process that we shall describe later in more detail. There are two ways a card is reset:

  • Warm Reset: When a Signal is sent through this pin to reset the ICC. 
  • Cold Reset: When the supply voltage is turned off and on again. Ejecting the card out and inserting again will have the same effect.

Clock pin is used to drive the logic of the embedded IC and is also used as the reference for the serial communications synchronization. This pin is provided because the ICC doesn’t have any clock generator onboard and needs this as external input. The card reader device provides this clock. The clock frequency is 5MHz generally but many high end ICCs use frequency multipliers to operate at higher frequencies up to 40 MHz.

Vpp pin is now optional and used only in old cards. Previously it was used for the high voltage signal that is necessary to program the EPROM memory. It was provided with two voltage levels. The lower one (or the idle state) is held down by the Card Reader device, until the higher level (or the active state) is required.

I/O pin is the serial input/output (SIO) connector. This is the signal line by which the underlying circuit receives commands and interchanges data with the outside world. This process will be explained in more detail when we talk about programming applications that receive these commands.

What is ATR ?

ATR

ATR is used for conveying parameters that are required by the card to establish a data communication pathway. This message is conveyed as soon as the power in the smart card is set to on and stands for answer to reset (ATR).

It is usually up to 33 bytes, contains the transmission parameters such as T = 0 and T = 1, which are supported by the card. It also carries all the necessary information that is required to be known by the host such as:

  • Data transmission rate
  • Card hardware parameters
  • Chip serial number
  • Mask version number

What is an APDU?

Answer 
The APDU (Application Protocol Data Unit) is the communication unit between a reader and a card. The structure of an APDU is defined by the ISO 7816 standards.

There are two categories of APDUs: command APDUs and response APDUs. As the name implies, the former is sent by the reader to the card: it contains a mandatory 5-byte header and from 0 to up to 255 bytes of data. The latter is sent by the card to the reader: it contains a mandatory 2-byte status word and from 0 to up to 256 bytes of data.

The APDU is an application level protocol as specified in the ISO 7816-4, which takes place between a smart card and a host application for the communication purpose.

APDU consist of two structures, as defined below:

  1. Command APDU (C-APDU: this command is used by the host application to send command to the card.
    1. Header: it consist of 4 bytes:-
      1. Class of instruction (CLA)
      2. Instruction code (INS)
      3. Parameters: P1 and 2
    2. Optional body: varies in length.
      1. Lc = specifies the length of the optional body or the data field (Bytes).
      2. Le = specifies the length of the data or the number of bytes that the host is expecting in response to the command sent.
      3. Data field contains the data that are sent to the card for executing the instruction specified in the header. 
  2. Response APDU (R-APDU): this command is used by the card in order to respond to the command send by the host application.
    1. Optional body: it consist of data field whose length is specified by the Le
    2. Trailer: it consist of two words SW1 and SW2 called as status word, which denotes the processing state in the card after the execution of the command APDU.

Structure of the APDU is given below:

1. Command APDU

 

Mandatory Header Optional body
CLA INS P1 P2 Lc Data Field Le

 

2. Response APDU

 

Optional body Mandatory Trailer
Data Field SW1 SW1

 

Note:

  • A command is always paired with response APDU
  • The data field is optional in both command APDU and response APDU.

The second case further divides the command and response APDU in four categories.

  1. There is no transfer of data to or from the card
    1. C- APDU: contains header only.
    2. R- APDU: contains only the trailer status word. 
  2. There is no transfer of data to the card but data are returned from the card
    1. C- APDU: contains Le only, which specifies the number of data bytes in the corresponding response APDU. 
  3. There is transfer of data to the card but no data is returned from the card
    1. C- APDU: contains Lc and data field, Lc which specifies the length of the data field.
    2. R-APDU: contains the trailer status word SW1 and SW2. 
  4. There is transfer of data to the card and data is returned from the card
    1. C- APDU: contains Lc and data field and Le.
    2. R-APDU: contains both the optional body and the trailer status word SW1 and SW2.
