Re: File No. EB-07-SE-031
Dear Mr. McCormack:
This is an official CITATION, issued pursuant to section 503(b)(5) of the Communications Act 
of 1934, as amended (Act), 47 U.S.C.  503(b)(5), to Phonejammer.com (Phonejammer) for 
marketing in the United States unauthorized radio frequency devices in violation of section 302(b) of the 
Act, 47 U.S.C.  302a(b), and section 2.803 of the Commissions rules (Rules), 47 C.F.R.  2.803, and 
for failing to respond to Enforcement Bureau directives to provide certain information and documents.  
As explained below, future violations of the Commissions rules in this regard may subject your company 
to monetary forfeitures.
By letter of inquiry (LOI) dated November 6, 2007, the Spectrum Enforcement Division 
(Division) of the Commissions Enforcement Bureau initiated an investigation into whether 
Phonejammer is marketing in the United States unauthorized radio frequency devices, specifically, radio 
frequency jammers which can disrupt communications on cellular and Personal Communications Service 
frequencies.  At the time of that letter, November 6, 2007, and again on, May 20, 2008, we observed on 
your website, www.phonejammer.com, advertisements for the sale of multiple radio frequency jammers.  
Your advertisements for the phone jammers listed shipping costs to the United States and displayed 
product prices in United States dollars.  In addition, your website provided testimonials from United 
States residents who had purchased your phone jammers. 
In response to our LOI, you sent the Division three emails, one received on November 6, 2007, 
one received on November 7, 2007, and one received on November 8, 2007.  In these emails, you claimed 
that your company is based in the United Kingdom and that you do not distribute, market, or advertise the 
phone jammers in the United States.  
In a response email sent by the Division, you were instructed to answer each question in the LOI.  
Further, the November 6, 2007 LOI directed you to support answers with an affidavit or declaration to be 
signed under penalty of perjury by an officer of the company who has personal knowledge of the 
representations and can verify that the company has produced all the information requested that is within 
its possession, custody, control, or knowledge.  Though your reply emails indicate that you received our 
LOI, you subsequently failed to respond to the questions set forth in the LOI.

Section 302(b) of the Act provides that [n]o person shall manufacture, import, sell, offer for sale, 
or ship devices or home electronic equipment and systems, or use devices, which fail to comply with 
regulations promulgated pursuant to this section.  Section 2.803(a)(1) of the Commissions 
implementing regulations provides that:
no person shall sell or lease, or offer for sale or lease (including advertising for sale or lease), or 
import, ship, or distribute for the purpose of selling or leasing or offering for sale or lease, any 
radio frequency device unless  [i]n the case of a device subject to certification, such device has 
been authorized by the Commission in accordance with the rules in this chapter and is properly 
identified and labeled as required by  2.925 and other relevant sections in this chapter.
Pursuant to section 15.201(b) of the Rules, 47 C.F.R.  15.201(b), intentional radiators1 must be 
authorized in accordance with the Commissions certification procedures prior to the initiation of 
marketing2 in the United States.  Based on your failure to provide FCC Identification numbers or other 
documentation showing that the jammers you market have been certified, as well as our review of the 
Commissions equipment authorization database, it appears the devices advertised on 
www.phonejammer.com have not been certified.  Moreover, it does not appear that these devices are 
capable of receiving a grant of certification.  In this regard, the main purpose of cell phone and other 
wireless jammers is to block or interfere with radio communications.  Such use is clearly prohibited by 
section 333 of the Act, 47 U.S.C.  333, which states that [n]o person shall willfully or maliciously 
interfere with or cause interference to any radio communications of any station licensed or authorized by 
or under this Act or operated by the United States Government.  Thus, a device such as a jammer which 
intentionally interferes with radio communications is not eligible for certification.3 Accordingly, it 
appears that Phonejammer has violated section 302(b) of the Act and section 2.803 of the rules by 
marketing in the United States the unauthorized radio frequency devices listed on its website.   
We note that the evidence before us contradicts Phonejammers claim that it is not marketing its 
jammers in the United States.  In this regard, we note, among other things, that Phonejammers website: 
(1) lists all phone jammer prices in United States dollars; (2) at check-out has the United States as the 
default shipping location; (3) includes testimonials of United States residents who have purchased its 
phone jammers; and, (4) advertises phone jammers intended to interfere with United States cellular and 
Personal Communications Service frequencies.
Sections 4(i), 4(j), and 403 of the Act,4 afford the Commission broad authority to investigate the 
entities it regulates.  Section 4(i) authorizes the Commission to issue such orders, not inconsistent with 
this Act, as may be necessary in the execution of its functions.  Section 4(j) states that the Commission 
may conduct its proceedings in such manner as will best conduce to the proper dispatch business and to 
the ends of justice.  Section 403 grants the Commission full authority and power at any time to institute 
an inquiry, on its own motion, in any case and as to any matter or thing concerning which complaint is 
authorized to be made, to or before the Commission by any provision of this Act, or concerning which 
  
1 Section 15.3(o) of the Rules defines an intentional radiator as a device that intentionally generates and emits 
radio frequency energy by radiation or induction.  47 C.F.R.  15.3(o).
2 Section 2.803(e)(4) of the Rules defines marketing as the sale or lease, or offering to sale or lease, 
including advertising for sale or lease, or importation, shipment or distribution for the purpose of selling or 
leasing or offering for sale or lease.  47 C.F.R.  2.803(e)(4).
3 Furthermore, section 2.803(g) of the Rules provides that radio frequency devices that could not be authorized or 
legally operated under the rules shall not be operated, advertised, displayed, offered for sale or lease, sold or leased, 
or otherwise marketed absent a license issued under part 5 of this chapter or a special temporary authorization issued 
by the Commission.  47 C.F.R.  2.803(g).

any question may arise under any of the provisions of this Act.  Pursuant to this authority, we sent you 
the November 6, 2007 LOI directing you to provide certain information and documents.  Your email 
responses indicate that you received the LOI.  However, your responses failed to address the questions set 
forth in the LOI.  Accordingly, it appears that Phonejammer has violated Commission orders by failing to 
respond to Enforcement Bureau directives to provide certain information and documents.
A party may not ignore the directives in a Bureau inquiry letter.5 You are again ordered, pursuant 
to sections 4(i), 4(j) and 403 of the Act, to provide the information sought by our November 6, 2007 LOI.  
You must provide this information within 20 days of the date of this Citation.  If sent by mail, this 
information should be sent to Zachary Rothstein, Spectrum Enforcement Division, Enforcement Bureau, 
Federal Communications Commission, 445 12th Street, S.W., Room 3-A326, Washington, D.C. 20554.  
Phonejammer must also transmit a copy of this information via facsimile to 202-418-7290.
If, after receipt of this citation, Phonejammer.com violates the Communications Act or the 
Commissions Rules in any manner described herein, the Commission may impose monetary 
forfeitures not to exceed $11,000 for each such violation or each day of a continuing violation.6
If you choose to do so, you may respond to this citation within 30 days from the date of this letter 
either through (1) a personal interview at the Commissions Field Office nearest to your place of business, 
or (2) a written statement.  Your response should specify the actions that Phonejammer.com is taking to 
ensure that it does not violate the Commissions rules governing the marketing of radio frequency 
jamming devices in the future. 
Please call Zachary Rothstein at 202-418-0608, if you wish to schedule a personal interview.  
You should schedule any interview to take place within 30 days of the date of this letter.  You should 
send any written statement within 30 days of the date of this letter to:

Under the Privacy Act of 1974, 5 U.S.C.  552(a)(e)(3), we are informing you that the 
Commissions staff will use all relevant material information before it, including information that you 
disclose in your interview or written statement, to determine what, if any, enforcement action is required 
to ensure your compliance with the Communications Act and the Commissions rules. 
  
5 See, e.g., SBC Communications, Inc., Forfeiture Order, 17 FCC Rcd 7589, 7591 (2002).  In SBC Communications, 
the Commission assessed a $100,000 forfeiture against a carrier for its willful refusal to supply a sworn declaration 
in response to an Enforcement Bureau letter of inquiry.  The Commission stated:  [T]he order here was squarely 
within the Commissions authority and, in any event, parties are required to comply with Commission orders even if 
they believe them to be outside the Commissions authority.  Id. at 7591.
