Opinion

BALDOCK, Circuit Judge.

The government appeals the district court’s dismissal of a four count indictment against Defendant John K. Brady on the grounds that the indictment was insufficient as á matter of law. We have jurisdiction pursuant to 18 U.S.C. § 3731.

I.

Expert testimony below, as thoroughly summarized by the district court, see United States v. Brady, 820 F.Supp. 1346 (D.Utah 1993), established the following description of the operation of cellular telephones. Cellular telephone service is based upon a system of individual cellular telephone units, which have wireless radio transmission capabilities, operating among a series of geographic cells. Each geographic cell is served by a radio transmitter, and. as the cellular telephone user moves from one pell to another, transmission of telephone calls are shifted from one transmitter to the other.

Cellular telephones are typically programmed with two identifying numbers. The mobile identification number (“MIN”) is a ten digit number (usually the area code and telephone number) assigned to the customer’s cellular telephone by the cellular carrier when the customer subscribes to that carrier’s service. The electronic serial number (“ESN”) is an eight digit number programmed onto an electronic chip by the tele *336 phone manufacturer. When a telephone call is initiated, the cellular telephone unit transmits the MIN and ESN to the cellular system.

Another feature provided by cellular carriers allows a cellular telephone customer to “roam,” placing calls from a geographic cell belonging to a carrier with whom they do not have an account. This feature allows a Salt Lake City customer, for example, to use his Salt Lake City cellular telephone to make a local or long distance call while in New York City. When a roaming customer places a call, his telephone transmits the MIN and ESN. The roaming carrier, e.g., the New York City carrier, recognizes the MIN as belonging to another carrier, e.g., the Salt Lake City carrier, but cannot instantly validate the call because the validation system does not allow instantaneous inter-carrier validation. Rather than delay service to the roaming customer, the roaming carrier accepts this first call from the roaming customer before it has had an opportunity to validate the MIN and ESN as a legitimate combination. 1 While the “first call” is taking place, a computer communicates with a central database of all legitimate MIN/ESN combinations. If the MIN/ESN combination does not match a valid combination in the home carrier’s computers, subsequent calls using the same combination will not be allowed. Telephone calls attributed to “unmatched” MIN/ESN combinations are listed individually in the cellular carrier’s billing computer, along with the charges associated with each individual call, but the user cannot be identified and the charges cannot be collected from him.

Cellular telephones can be altered by either replacing or reprogramming the microchip containing the unit’s MIN and ESN. Telephones altered in this manner can be used either as “clones” or “free riders” to circumvent the normal cellular telephone system billing process. Cloning involves the programming of a cellular telephone so that the MIN/ESN combination is identical to a combination assigned to a legitimate customer. By cloning, the user accesses the legitimate customer’s account to obtain free telephone service until the legitimate customer recognizes and reports the unauthorized charges.

Free riding involves the use of “tumbling” cellular phones. Free riding is achieved when the microchip that holds the MIN and the ESN has been modified to allow the user to change or tumble the MIN/ESN combination in his telephone at will by programming and reprogramming the MIN, the ESN, or both, from the key pad. The user programs a random MIN/ESN combination into the unit and continues using it until the validation system determines that it is invalid and blocks further calls. In this way, the user free rides the cellular telephone system and takes advantage of the roamer service by continually making a series of unmatched first calls, without ever being charged for the calls.

II.

On October 24, 1992, the grand jury returned an indictment charging Defendant with four counts of violating 18 U.S.C. § 1029(a)(1). Counts I through III alleged that Defendant, in pertinent part:

knowingly, and with intent to defraud, trafficked in a counterfeit access device, as defined in 18 U.S.C. § 1029(e)(2); that is, an altered cellular telephone, permitting unauthorized access to telephone services, such conduct having an effect on interstate commerce, all in violation of 18 U.S.C. § 1029(a)(1).

Count IV alleged that Defendant, in pertinent part:

knowingly, and with intent to defraud, used a counterfeit access device, as defined in 18 U.S.C. § 1029(e)(2); that is, an altered cellular telephone, permitting unauthorized access to telephone services, such conduct having an effect on interstate commerce, all in violation of 18 U.S.C. § 1029(a)(1).

Defendant moved to dismiss the indictment as insufficient, claiming that it failed to state an essential element of the offense, i.e., *337 that- Defendant used or trafficked in an access device that gained access to a billed account. Defendant also moved to suppress statements he made during the course of the investigation and to dismiss the indictment based on the government’s breach of an agreement not to prosecute. Following a three-day evidentiary hearing oh Defendant’s motions, Defendant filed a third motion to dismiss the indictment, this time based on insufficiency of the evidence.

At the hearing, the government presented evidence that Defendant used and trafficked in four tumbling Mitsubishi Series 800 cellular telephones. Testimony established that these telephones had been altered so that the caller could obtain telephone service by free riding the system. Defendant admitted at the hearing that he had used a tumbling cellular telephone to place some 1300 calls over several months; however, the government conceded that it could not prove that Defendant, or any of the four telephones associated with Defendant, actually accessed identifiable subscriber accounts.

The government’s offer of proof concerning account access came from employees of Cellular One of Salt Lake City — one of two cellular telephone companies in Salt Lake. The employees testified that unmatched calls and the charges created by the calls are reflected in Cellular One’s records.
