Appellant United States of America (the “government”) appeals the acquittal of Kenneth Steven Bailey (“Defendant”) of charges involving production of, and trafficking in, counterfeit access devices in violation of 18 U.S.C. § 1029(a). We have jurisdiction pursuant to 28 U.S.C. § 1291 and reverse the district court.
I. Background
A. Facts
A cellular phone places a call by transmitting its permanently assigned identification number (known as the electronic serial number or “ESN”), its assigned phone number (the Mobile Identification Number or “MIN”), and the number being called to a nearby antenna or “cell.” For a local customer, the local network confirms that the ESN and MIN match before completing the call.
To accommodate customers out of then-service area, local cellular networks permit phones other than those subscribing to the local service to complete calls in “roaming” mode. At the time of Defendant’s activities, roaming mode was more vulnerable to fraud than was the service to local subscribers. When a call was placed by a phone with an out-of-area MIN, the local service would first determine whether there was a roaming-agreement between the local carrier and the carrier responsible for the MIN (the “distant carrier”); if there was, the local carrier would connect the call unless the ESN was found in a list of invalid ESNs, known as the “negative file.” In roaming mode, the local carrier could not confirm that the ESN and the MIN matched.
Defendant modified cellular telephones so as to fool the local network into permitting calls placed by those phones to be completed in roaming mode, even though the call could never be billed. This sort of scheme is known in the industry as “tumbling the ESN.” The process involves altering the programming embedded in the hardware of the telephone to cause the phone to send out random ESNs. By changing the MIN in the phone to one in another area, the user could force the phone to place calls in roaming mode. Then, by transmitting any ESN not listed in the negative file, the user could trick the local carrier into connecting the call. The liability of the distant carrier for calls by “tumbler” phones is not entirely clear. 1 We assume solely for the sake of argument that the local carrier is not reimbursed by the distant carrier for such calls because the local carrier cannot establish that the call was made by a valid subscriber to the distant carrier’s service.
Defendant read the program in the phone and rewrote it so that it randomly changed *416 the ESN. He then encoded the program (“burned” it) into new chips (“EPROMs”) that could replace the chips in the phones. Defendant was arrested after selling five of the modified chips to an undercover Secret Service agent. Defendant consented to a search of his motel room, which produced materials and equipment used to produce the chips, including extra chips, computer software, a data erase clip used to erase chips, and a receipt for purchase of Mitsubishi cellular phones. He admitted that he had produced and sold some 150 chips with his program to override the internal security program of the phone. The chips sold to the Secret Service agent contained modified versions of the original programs on the chips installed in Mitsubishi phones.
B. Prior Proceedings
Defendant was indicted on January 22, 1991, for manufacturing and trafficking in counterfeit access devices, in violation of 18 U.S.C. § 1029(a)(1), and possession of equipment to make such devices, in violation of 18 U.S.C. § 1029(a)(4). A superseding indictment also charged attempted manufacture of, and traffic in, counterfeit access devices in count one. During trial, Defendant moved for acquittal on the ground that the computer chips in question were not “counterfeit access devices” within the meaning of the statute. The motion was denied. On June 1, 1992, a jury convicted Defendant of both counts. Defendant made a Rule 29 motion for a judgment of acquittal on the same basis as his earlier motion. The district court granted that motion on November 9, 1992. The government timely appeals, joined by two amici, the Cellular Telecommunications Industry Association and the Communications Fraud Control Association, and challenges the district court’s interpretation of the statute.
II. Discussion
A. Issue on Appeal
We review de novo the district court’s interpretation of section 1029.
United States v. Brannan,
The district court decided that Defendant’s handiwork did not constitute an “access device” within the meaning of the statute. The court explained its conclusion by stating that
[wjhat legislative history there is indicates that the purpose of this legislation was to prevent access to accounts.... [I]f you follow the Government’s line of reasoning then even a.crowbar could be an access device because you could use it to pry open an ATM machine. I mean that’s a line of — that’s a conclusion if you follow the Government’s line of thinking, anything that you can use to get into a system that has accounts is an access device. And a crowbar would fit that definition perfectly as much as an EPROM.
The district court seemed persuaded by the idea that there was no evidence that the distant carrier ever suffered a direct accounting loss (i.e., had to disburse funds) due to the tumbling. It seemed to believe that the inability to bill for the calls was just a failure to collect additional revenue from potential customers, and that there was no additional cost to providing the additional calls. That characterization of the transaction apparently led the court to follow
United States v. McNutt,
McNutt
involved the sale of satellite TV descramblers that used electronic addresses
*417
“cloned” from a legitimate unit to allow decryption of pay television services. The Tenth Circuit ruled that such activity did not violate § 1029 because the cloned de-scramblers did not actually debit the accounts of legitimate subscribers and the statute did not protect against indirect economic harms caused by “free riding.”
We disagree with the conclusion of the district court. The district court erred at two points in its conclusion. First, the phones do access an account, and it is irrelevant that no third party ever ended up footing the bill. Second, its characterization of the transaction was incorrect (there was a cost), and McNutt is properly distinguished.
B. Account
On appeal, Defendant argues that no “account” was involved because the ESNs broadcast by his invention did not correspond to accounts of real customers. The government responds that the statute was not meant to be so narrowly construed. The statute, unfortunately, does not define “account.” The
McNutt
court looked to the dictionary and came up with a definition: “a formal record of debits and credits.”
The district court’s holding turns on the idea that no account was accessed because the fabricated ESNs did not correspond to any particular customer’s account for cellular service. Two other circuits, however, have decided that § 1029 reaches access to unassigned accounts. In
United States v. Brewer,
We agree with those cases that actual or potential recourse by the provider of the goods or services against the party for whose *418 benefit the account is maintained is not a necessary element of “account access” under § 1029. It matters only that the user of the access device be able to obtain goods or services from which he would otherwise be excluded.
As for the claim that no actual account was implicated by defendant’s activities, we need not worry about whether or not the ESNs broadcast by the tumbling phones correspond to valid or assigned customer accounts (or whether any such condition is imposed by the statute) because we find that there unquestionably was a valid, preexisting “account” between the local and distant carriers.
Contra Brady,
McNutt is distinguishable on this point. The code numbers used to construct the de-scramblers were not represented to the broadcasters in an attempt to obtain services on account. Instead, the signal was openly broadcast, and anyone could receive it. In deciding to provide the signal, the broadcaster never relied on any representation of the existence of an account. In effect, it was not the signal that was sold; instead, the de-scramblers were rented to make that signal useable. In the case of cellular carriers, on the other hand, the sale of “air time” is the
primary good sold; cellular carriers frequently have nothing to do with the production or sale of the phones themselves. Contrary to Defendant’s arguments, the ESN and MIN are not just part of an after-the-fact billing device; they are part of a system designed to permit access only by those so entitled because of an account.
The fact that the “cloning” of descramblers is prohibited by a separate statutory scheme is also indicative of the differences involved. The Electronic Communications Privacy Act prohibits the manufacture, possession, or sale of devices “primarily useful for the purpose of the surreptitious interception of wire, oral, or electronic communications,” including cloned satellite television descramblers. 18 U.S.C. §§ 2512(1);
see United States v. Lands,
C. “Free Riding”
The defendant nevertheless attempts to analogize his devices to those in
McNutt
by claiming that he is merely “piggybacking” onto an an existing system and getting a “free ride” without actually imposing any costs on anyone. The Tenth Circuit accepted that characterization in extending the holding of
McNutt
to tumbling the ESN.
Brady,
III. Conclusion
We disagree with the district court’s, and the Tenth Circuit’s conclusion in Brady, that the practice of “tumbling” the ESN is beyond the reach of 18 U.S.C. § 1029. We hold that the placement of a cellular phone call by such means accesses an account in order fraudulently to obtain services. While we make no comment on the propriety of the holding of McNutt, we find the activities involved in that case are properly distinguished from those in this case. The judgment of acquittal entered by the district court is VACATED. We REMAND the case with instructions to reinstate the jury’s verdict, and for such further proceedings as may be appropriate.
Notes
. Defendant states that no evidence was presented that any account-holder (distant carrier) ever had to pay for a call placed by a tumbler phone. The government implies that the distant carrier is liable to reimburse the local carrier. Amicus Cellular Telecommunications Industry Association states that the local carriers cannot seek reimbursement for fraudulent calls through the settlement process. Amicus Communications Fraud Control Association implies that the carrier responsible for the MIN is saddled with the uncollectible toll even though it had to reimburse the local carrier. As explained below, it is the existence of the account, not the person ultimately left responsible for the call, that is important in this case.
