Cell phones. Everybody knows what they are. But haven't you
tried to understand them a little better? Like, how the hell
your cellphone connects to the "server" or shit like that?
Well, this tutorial reveal some of these secrets, and invite
you to research a little. Dive into the world of DTMF...
By the way... This tute is not very easy to understand at
first sight, because it has a lot of technical only information.
I know that. If you have any doubts mail me at bitchz@usa.net
-------------------------[Intro Q&a]--------------------------
Q: What is a cell phone?
A: A 800 mhz radiotelephone, running 3 watts, with the ability
to change channel on computer command from the central switch.
This happens when you travel thru the service area and your
signal becomes stronger at a neighboring cell base station.
Q: They are marketed as a high security device with no
possibility of anyone making a phoney call and charging it to
someone else, how can it be phreaked?
A: An understanding of the phone reveals that every time a call
is made, the phone number,an electronic serial number, and
other data is sent to the switch. If you were to listen to the
oposite side of the control channel as the call is being "set-up"
you would hear this data being transmitted to the switch in NRZ
code (non-return to zero). All one has to do, is record this
info and program the bogus phone to these params and a free call
is possible thru the switch.
---------------------[Getting to business]----------------------
.Behind the calling process. An intro to the magic numbers:
When a cellular phone makes a call, it normally transmits it's
Electronic Security Number(ESN),Mobile Identification Number(MIN),
it's Station Class Mark(SCM) and the number called in a short
burst of data. This burst is the short buzz you hear after you
press the SEND button and before the tower catches the data.
These four things are the components the cellular provider uses
to ensure that the phone is programmed to be billed and that it
also has the identity of both the customer and the phone.
.The Hack Begins
The ESN and the phone number (MIN) are the two primary identifiers
for any cellular phone. By changing both, the cellular carrier
will accept the call and bill it to either a wrong account or
provide service based on the fact that it is NOT a disconnected
receiver. It will also look at the other two components, in order
to insure that it is actually a cellular phone and to forward
billing information to that carrier.
Ok, this gave you some ideas didn't it? I should have guessed.
You're already thinking on how to change these two simple numbers.
The Station Class Mark can also be changed if you wish to prevent
the cellular carrier from determining the type of phone that is
placing the call. By providing the cellular tower with a false SCM,
the cellular carrier, the FCC, or whoever happens to chase down
cellular fraud is often looking for a particular phone which in
reality is not the phone they are looking for. For example, you
can provide the SCM for a Radio Shack phone, when in reality you
are using a Novatell (How this is done from changing the SCM I do
not know...remember...I didn't write this).
The Number Assignment Module (NAM) also has the SIDH (System
Identification for Home System) number programmed into it. Refer to
SIDH TABLE. The transmittal of the SIDH number tells the carrier
where to forward the billing information to in case the user is
"roaming". The SIDH table tells the major cities and their
identifying numbers. Changing an SIDH is programming job that
takes only minutes, but be aware that the ESN is still sent to
the cellular phone company. After they realize that the ESN is
connected to either a fake number or a phone that is not in the
network, they will block service. They only way around this is
to reprogram the ESN.
.Nams
Number Assignment Module - A 32 word by 8 bit PROM The NAM
contains all the information that can be programmed to the
phone directly from the handset. (i.e. SIDH,MIN,LOCK-CODE,etc.)
Ok. Now you've got an idea of what you can do with these so
called ultra-mega-secure-phones (Yeah, right)...
----------------------[The modifications]----------------------
[How to get ESN/MIN pairs, the magic stuff]
Now Methods for obtaining this valuable information varies,
I'll give you a few personal examples on how I was able to get some
pairs. One method (which was lo-risk and cheap) was to do the
old infamous trashing, I cased out a local cell provider branch
office, found out what were there days/hours of operation, snooped
and asked some questions on how they deal with fraud, (social
engineering skills were needed of course), to which the only answer
they could provide was "oh , well if you didn't make the calls, we
will not require you to pay for them, and we'll change your number"
which gave me two good pieces of information, 1 they just chalk it
up to loss , to appease the customers, and two, they don't give a
fuck in finding out who made the calls. Now that was good to hear,
so on the day before trash collection I simply parked my car by the
dumpster, (flashlight in my pocket), and simulated taking a leak
behind the trash bin, quickly I open the side access panel, and did
a quick search, I found 3 bags with words (cellular, contract)
clearly visible in the bags, I grabbed them, look around, and
tossed them in the trunk. After getting them to my garage (it was
about 11:30 pm too) and sifting through the coffee filters, and
salad containers, I walked off with about 100 pairs. (written
contract info which is discarded after its entered into the
computer). The cons to this is that you got a lot of explaining to
do to the cops if they see you toss some bags of trash in your
trunk, and some states have laws governing trash, to the effect of
the trash being the property of the company until its collected by
a designated trash refuge agency, non-the-less , this works for
some places, Cell-1's here, have a company called 'Document
Services' which pick up their trash, and shred the ESN/personal
papers and contracts, thus this is ineffective in some areas.
.Another more expensive way, is to obtain a device called a
DDi, Digital Data Interface, this thing comes in various formats
from the more expensive stand-alone box, to a device which
interfaces with your 800 mhz capable scanner and a PC, the cheapest
standalone I seen was $1295, also I saw a kit for a simple one for
about 1-$200, this is the safest way do get pairs, simply make the
device mobile, and sit in a busy traffic area (freeway overpass)
and collect all the data you need.
.These are just a couple of examples on obtaining the 'magic
numbers' , some other ways (trading, inside help) does work too,
but are sometimes not effective, try to be creative, the Fedz know
about the trashing from back to the Captain Crunch days, the DDi
seems to be the logical choice for snarfing.
No need to say that, after getting the pair of numbers, you have
to program them in your cell phone. We will get to this...
[Continuing on the numbers]
Well if you haven't guessed by now, the mobiles ESN and MIN must
match in the switch or no go. This is required for billing
purposes. If one had the ESN and the mobile phone number (MIN),
he could call anytime and anyplace without fear of a trace - let
alone a bill. The ideal setup would let you listen with a scanner
to the reverse control channel, record and display heard working
numbers and ESN's, and recall them as one needs to make calls.
This would be it, but we are not quite there yet. But some of the
hard work has already been done for us. All the aforementioned
codes are sent in hex, in NRZ code (phase-key shifting), when a
cellular subscriber places a call. But guess what? All phones
have an NRZ receiver and transmitter built right into them. All
that has to be done is to have a receiver on the reverse control
channel, recover the other subscibers data and save it or print
it out.
Cellular phones operate on a full duplex channel. One frequency
is used for transmission from the base to the phone, while another
is used for transmission from the phone to the base. The base
frequencies are always exactly 45 MHZ higher than the phone
frequency, and both of these are incremented by 30 KHZ as the
progression of channels increases from Channel #1 to Chanel #1023
(NOTE: There are no channels between 800 and 990).
With some systems (not all) the cellular transmission is received
by the base and retransmitted on the base frequency. When this is
done, a scanner can listen to both sides of the conversation by
simply monitoring the base frequency. When this is not the case,
two scanners set 45 MHZ apart will work.
Here is a list of all Cellular Frequencies:

Here is a method of determining which frequencies are used in a
cellular system, and which ones are in what cells. If the system
uses OMNICELLS, as most do, you can readily find all the channels
in a cell if you know just one of them, using tables constructed
with the instructions below.
Cellular frequencies are assigned by channel number, and for all
channel numbers, in both wireline and non-wireline systems, the
formula is:
Transmit Frequency = (channel number x .030 MHz) + 870 MHz
Receive Frequency = (channel number x .030 Mhz) + 825 Mhz
"Band A" (one of the two blocks) uses channels 1 - 333. To construct
a table showing frequency by cells, use channel 333 as the top left
corner of a table. The next entry to the right of channel 333 is 332,
the next is 331, etc., down to channel 313. Enter channel 312
underneath 333, 311 under 332, etc. Each channel across the top row
is the first channel in each CELL of the system; each channel DOWN from
the column from the the first channel is the next frequency assigned
to that cell. You may have noted that each channel down is 21 channels
lower in number. Usually the data channel used is the highest numbered
channel in a cell.
"Band B" uses channels from 334 to 666. Construct your table in a
similar way, with channel 334 in the upper left corner, 335 the next
entry to the right. The data channel should be the lowest numbered
channel in each cell this time.

---------------------------[Programming the NAM]---------------------
I have to say that, as this is very specific information, regarding
each particular telephone, i could not (you'll understand why) gather
it all in this tuturial. So i decided to put one or two examples on
how this stuff is done for some models of cell phones. You'll have
to find out how to program it on your very own model. Perhaps you
can ask those guys at nokia:
"Guys! I'm trying to program my cell phone so I don't have to pay
my calls. Can you help me do that???"
Ehehehe. I guess you know this was a joke. and an awful one too.
Well, back to the tute, ok? Well. with this tuturial, it came a zip
file named examples.zip right? Well, open it and explore. Here you'll
find the instructions on how to program some models. Not very actual
information I must say. I'm terribly sorry for that. But if you want
I can try to mail you the information I have in programming more
modern cell phones.
.............................examples.zip.........................
............... ...open it, explore and come back.................
------------------------------[Outro]--------------------------------
Well. How was it? I know it is complicated to understand if you don't
have the bases. I'll try to make a real INTRO to phones tutorial soon
ok?
Next tutorial will be: The Global Positioning System
