After examining some other files on cellular phreaking, I discovered some of the primary sources of his material are several articles written by The Mad Phone Man, an article on IMTS by The Researcher (of this bbs (P-80), and numerous other sources. Raven would suggest that this is his knowledge. One example of this a question and answer segment that Mad Phone Man had in one of his cell phreaking series. Raven has substituted his name where the answers are similar to a type writtin copy of a conversation, whereby the person speaking at the moments name is at the beginning of that line or lines. Thus it appears that Raven would like us to beleive him knowledgable on this subject. NOT! He has also removed all original credits of the real authors. Sounds like another teenager on an ego/power trip. However, even though some of this material is duplicated on this system, some is not, so im gonna run it. I do hope the technical data survived his COMPILING of this data better than his spelling and use of the english language. Scan Man) Hmmm.... Another text file.. Make sure that you keep this one for your collection!! There is no other text file that is more complete or up-to date that explains cellular phone phreaking like this one for 1992!!! Since this is going to be a complete manual it has been broken-up into 2 parts so this is manual 1. I'm hoping that there will be some info. on cellular phreaking published in PHRACK that may be able to help you and me with our endevors but I'm waiting. Another thing that I just found out is that the Hack/Phreak Community is in need for a BBS that doesn't give bullshit info (most do!) and thats cause our world has been infiltrated with narcs and telco/bell agents that try to spread as much misinformation as possible!! But there are a few bbs's that keep the faith and they will be listed at the end of this text.

NOTE =-==-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= CELLULAR PHREAKER TYPES ----------------------- There are two types of cellular phone phreakers. The first type is the one whos's intrested in scanning cellular phone channels basically to overhear conversations. The second type is the one who obtains and modifies cellular equipment so that he can make free phone calls at someone elese's expense. I. IMPROVED MOBILE TELEPHONE SERVICE This system that was used prior to cellular phones was the Improved Mobile Telephone Service (IMTS), which was much easier to scan for. Most scanner enthusiasts are familiar with this standard mobile phone system; this system has gone thru little evolution in the past decade in the U.S. It has remained a considerably limited service. A large metro area may only have several hundred users, (New York City has about 900 mobile phone subscribers) dur largely to limitations imposed by spectral overcroeding. Land mobile commo has seen a 10-12% annual growth rate for the past two decades. The result is that the 40, 150 and 450 MHZ bands are overcrowded. Even the utilization of the new 900 MHZ band (with 30-40 times more channels available than other bands) is a short-lived solution to the problem. IMTS freqs (MHZ): Channel Base Freq.

If you live within 25-50 miles of even a moderate sized town, you should have at least one VHF high-band channel. VHF low-band IMTS is used in rural areas and those with hilly terrain. UHF IMTS is primarily used in cities where the VHF channels are crowded. If you live in a major city, expect to have most, if not all, of these channels available to you. II. GENERAL CELLULAR INFO This section is a little boring but it's needed to set a basic foundation of cellular phone phreaking so that part 2 doesn't sound like all technicial talk! The FCC originally estaablished 3 cellular bands. One was given to the local Bell or Telco, (wireline carrier), one to an independent firm (non-wireline carrier), and one reserved for future use. Originally there were 666 cellular freqs or channels. In recent years the FCC has tacked on another 156 freqs for a total of 832 freqs, and all cellular makers have upgraded their phones to accomodate the new channels. Some of the new channels appears above the original 666 while others appear below. The cellular system cannot know whether or not a cellular phone can be switched to one of the 156 channels without the phone telling it. This is done by the Station Class Mark (SCM), which is a 4-bit binary number. (1) Bit #1 is "0" for 666 and "1" for 832 (2) Bit #2 is "0" for a mobile unit and "1" for a voice activated transmit. (That saves batteries on portables.) (3) Bit #3 and #4 identify the power class of the phone: "00" = 3 watts "01" = 1.2 watts "10" = 0.6 watts and "11" is not assigned. The old traditional scheme for handling cellular traffic is the analog method or Frequency-Divison Multiple Access (FDMA). How the FDMA works is that free channels are found and each transmitter is assigned to one of them. When the call finishes, th echannels are freed up for the next call. Also, as the two parties become physically closer or more distant as they drive or travhghhggytel the call may be handed off to other freqs assigned to the new cells they are in. Newer proposed schemes include Time-Divison Multiple Acess (TDMA) and Code- Divison Multiple Acess (CDMA). IN TDMA systems, calls may simultaneously use the same channels but are interspered between the pauses in the conversation. Many pauses result not only in the way people normally think and talk but when one party is talking, the other is listening. With TDMA, the Cellular Phone Company (CPC) injects small delays in parts of conversations to accommodate other traffic on that channel. This increases the lenght of the average phone call, which also increases their profits from it - not to mention the fact that they can increase there output by the factor of 3 and also then expand their operation. CDMA is a system that's been used by military for the past 30+ years. CDMA appears to basically be a system where conversation are compressed into coded bundles and then decompressed at the other end. A Cellular Mobile Telephone (CMT) is one that is installed in a vehicle, aircraft, watercraft or whatever, as opposed to a transporable or portable unit. III. CELLULAR FREQS & CHANNELS There are 832 cellular phone channels. 416 of these are allocated for the non-wireline services (Band A), and 416 for the wireline services (Band B). Each of these channels have two freqs, spaced 45 MHZ apart, that operate in a full-duplex mode. The lower freq is for the phone unit, while the upper is for the cell or basesite. Of the 416 channels, 21 are digital data control or "set up" channels and 395 are voice channels. Channels are numbered 1 thru 1023, and there is a gap from 800 to 990. Rather than producing a list of 1646 cellular freqs, I have provided the math eqations that can be used to calculate them. These equations can be programmed into computers and calculators. N = Cellular Channel # F = Cellular Freq B = 0 (mobile), or B = 1 (base) CELLULAR FREQS from CHANNEL #S: ------------------------------- F = 825.030 + B*45 + (N-1)*.03 WHERE: n = 1 to 799 F = 824.040 + b*45 + (N-1)*.03 where: N = 991 to 1023 CELLULAR CHANNEL #s from FREQS: ------------------------------- N = 1 + (F-825.030-B*45)/.03 Where: F > = 825.030 (mobile) or F > = 870.030 (base) N = 991 + (F-824.040-B*45)/.03 Where: F < = 825.000 (mobile) or F < = 870.000 (base) 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 from these equations. Band A uses channels 1-333 under the old 666-channel system. To that have been added 667-716 and 991-1023 under the new 832-channel system. Band B uses channels from 334-666 under the old system, plus 717-799 under the new system. IV.

To do this youll obviously need an EPROM (Erasable Programmable Read-Only Memory) burner, as well as the same type of chips used in the phone (or a friendly & unscruplus dealer!). As to recording the numbers of other mobile phone customers and using them; as far as I know it is quite possible, if you got the equipment to record and decode it. The cellular system would possibly freak out if two phones (with valid ID/phone number combinations) were both present in the network at once, but it remains to be seen what will happen. The MIN is the Mobile Identification Number (includes the phone number, and it is stored on the NAM ROM). Stolen and spoofed ESN's and MINs are good for about a month. Once a bad MIN is revealed, the legit user's MIN is changed by the Mobile Telephone Switching Office (MTSO) and they arrange for a new NAM ROM to be installed in the users legit unit. Of course MTSO keeps a database of all legit,illegit and deadbeat MIN/ESN pairs. However, the MTSO will allow a illegit MIN/ESN pair to continue to function beyond its discovery in hopes of discovering who the phreaks are. One of the properties of cellular phone system is that the transmitter freqs may be changed or "hopped" in the constant effort to allocate freqs. Because of freq. hopping it is very difficult triangulate a CMT using standard RF directional finding methods. It is known that a directional antenna randomly aimed at cellsite repeaters will confuse directional finding equipment being used by them that is synced to their freq. hopping scheme. ROAMING Since cellular technology often results in physical seperation between the caller and-or callled party from landlines, because it offers thousands of lines to choose from, because freq. hopping occurs, and because the caller and-or called party can be rapidly moving from one location to another, cellular phnes are the safest form of phreaking. "Roaming" is one form of cellular phreaking. Roaming occurs when a CMT is used in a cellular system other than the one indicated in the NAMs SID. This is called "ROAMmode", and the ROAM indicator on the control head will light. A CMT can roam into any system its home CPC has a roaming agreement with, and most CPC's now have roam agreements with each other. Not every system pays attention to a "Roamer" from outside the system as cosely as they do a local suscriber. In their mad rush to offer cellular as "universal" service, they screwed up. If there's no roam agreement, the MTSO will transmit a recorded message to the CMT with some instructions to call the CPC, and gives his name ,MIN,ESN and credit card number. All roamed calls will then be completed by the MTSO and billed to the credit card account. This procedure is becomming less common as more roam agreements are made. Usually, CPC can only determine if a roamer came from a system with which it has a roaming agreement - nit the creditworthiness of the roamer. Consequently, many CPCs have been ripped-off by roamers who've been denied service on their home system because they are deadbeats. Once the home CPC is billed for the roaming services provided by the remote CPC to the phreaker or deadbeat, it will notify the same to add that ESN/MIN pair to their MTSO's "negative verify" file to prevent future abuses. Several independent firms are establishing systems software and data networks to allow POSITIVE ROAMER VERIFICATION (PRV), which allow near real time roamer validation bt sharing data between CPCs. Until PRV becomes universal, even bogus ESNs and MINs can roam if they follow the standard format, alto some CPCs are sharing roam data on a limited basis to prevent this. Even with PRV, ESN/MIN pairs that are spoofed to match valid accounts will be accepted both by thier home CPC and roamed CPCs, until the legit customer complains about the calls he didn't make. And even without PRV, some CPCs automatically share ESN and MIN data. This frequently occurs between the CPCs in major cities and those in their bedroom communities. To call a roaming CMT, the caller must know which system that unit is in, which can be a real trick since he may be on the road at the time. He then calls the CPC's roaming number. Roaming numbers vary but usually are in the phone number format (with area code, with the last four digits being "ROAM", and with the 3 middle digits being the remote CPC's exchange). When that number is called, a dial or ready tone is returned, after which the roaming CMT's full MIN is entered in Touch-Tone. After several seconds, the CMT will ring or the caller will hear a recording stating that the roaming CMT is out of range or busy. Telocator Publications (202) 467-4770 publishes a nationwide roaming directory for travellers with celluar phones. For example: I access the Cleveland Ohio Cellular 1's Ericcson switch and I tell them by my NAM INfo that I'm a roamer from NYNEX in New York City. Cleveland will let me make the call, bacause it bills back to NYC for the number of minutes I use. If the NYC number is bogus , the call goes thru anyway, and the bill doesn't go anywhere. They do know the exchange data for NYC (that's on a chart) so you can't tell them a wrong system number (two digits) but one that a valid roamer would have from his area. This is not too hard to figure out, call some of their stupid sales idiots some time and see what they let out of the bag. The system number for the foreign exchange, NYNEX in Buffalo is 56, Chicago nonwireline is 01, and Buffalo nonwireline is 03. All wirelines are even numbers and all nonwirelines are odd. The first three digits of the mobile number: NYNEX Buffalo 863-XXXX. Buffalo Non-wirelines are 861-XXXX and 690-XXXX. You dont have to be a rocket scientist to figure out the local numbers for your area, again by conning the sales people. Until the CPC's get a cellular clearinghouse to validate roamers in real time, this method will work out fine. It will be awhile before it becomes routine to look up a roamer. There's simply to many to look up every time service is wanted. And this problem is increasing because of the expanding use of cellular phones. If a cellular phone and its antenna happen to fall into your hands, you could re-nam it as a roamer and when you get it setup, make copies of the info with different suscriber numbers (the last 4 digits) and make free calls as long as you can. THe Novatel series phone a re probaly the best radios to use to shut down a cell site completely as it has secret codes in the control head that allow you to bypass conventional switching protocols. NOTE I hope that this file has lived up the all the boasting I've put into it. But if there are any problems with the freqs. or anything you can leave me mail on the bbs's I've listed.
