Text and Multimedia Messaging: Emerging Issues for Congress

Summary
The first text messages were sent during 1992 and 1993, although commercially, text messaging
was not widely offered or used until 2000. Even then, messages could only be sent between users
subscribed to the same wireless carrier, e.g., Sprint customers could only exchange messages with
other Sprint customers. In November 2001, however, wireless service providers began to connect
their networks for text messaging, allowing subscribers on different networks to exchange text
messages. Since then, the number of text messages in the United States has grown to over 48
billion messages every month. Additionally, text messages are no longer only sent as “point-to-
point” communications between two mobile device users. More specifically, messages are also
commonly sent from Web-based applications within a Web browser (e.g., from an Internet e-mail
address) and from instant messaging clients like AIM or MSN.
For Congressional policymakers, two major categories of issues have arisen: (1) “same problem,
different platform” and (2) issues stemming from the difficulty in applying existing technical
definitions to a new service, such as whether a text message is sent “phone-to-phone” or using the
phone’s associated email address. An example of the first category would be consumer fraud and
children’s accessing inappropriate content, which have existed previously in the “wired world,”
but have now found their way to the “wireless world.” An example of the second category would
be that spam sent between two phones or from one phone to many phones does not fall under the
definition of spam in the CAN-SPAM Act of 2003 (Controlling the Assault of Non-Solicited
Pornography and Marketing Act, P.L. 108-187); however, if that same message were to be sent
from a phone or computer using the phone’s associated e-mail address, it would.
The increasing use of text and multimedia messaging has raised several policy issues:
applicability of CAN-SPAM Act to unwanted wireless messages; refusal of some carriers to allow
users to disable text messaging; carrier blocking of Common Short Code messages; deceptive and
misleading Common Short Code programs; protecting children from inappropriate content on
wireless devices; mobile cyberbullying; and balancing user privacy with “Sunshine,” Open
Government, and Freedom of Information Laws.

commonly sent from Web-based applications within a Web browser and from instant messaging
clients like AIM or MSN. Table 1 tracks the historic growth of monthly text messaging between
2001 and 2007 from about 33 million to over 48 billion messages; Table 2 tracks the historic and
projected growth in the number of mobile customers using text messaging between 2003 and
2010 from about 32 million users to 100 million.

Text and Multimedia Messaging: Emerging Issues for Congress

Definitions
Short Message Service
Short Message Service (SMS) is a method of communication that sends text between cell phones,
or from a computer or handheld device to a cell phone. The “short” part refers to the maximum
size of the text messages: 160 characters.1 The term “SMS” is generally used interchangeably
with the term “text message.”
Even when not being used for a voice call, a mobile phone is constantly sending and receiving
information. It is communicating to its cell phone tower over a control channel. The reason for
this communication is so that the cell phone system knows which cell a phone is in, and so that
the phone can change cells as the user moves around. Every so often, a phone and a tower will
exchange a packet of data that lets both “know” that everything is working properly.
The control channel also provides the pathway for SMS messages. When someone sends an SMS
message, the message flows through the SMS Center (SMSC), then to the cell tower, and the
tower then sends the message to the recipient’s phone as a packet of data on the control channel.
Figure 1 illustrates how a SMS message is processed.

that SMS messages are not carried over it; SMS Aggregator = an intermediary between mobile service providers
providing SMS service; SMSC = SMS Center; SMPP = Short Message Peer-to-Peer Protocol.
Enhanced and Multimedia Message Service
While SMS only allows plain text to be sent, two alternative messaging services allow for more
elaborate types of messages. With Enhanced Messaging Service (EMS), formatted text, sound
effects, small pictures, and icons can be sent. MMS (Multimedia Messaging Service) allows
animations, audio, and video files in addition to text to be sent
E-mail-to-SMS Messaging
As noted above, SMS messages may be sent between a computer and a mobile phone. However,
these messages are sent using the e-mail address associated with the mobile device, such as
2025551212@carrier.com. For that reason, these messages are classified as e-mail and therefore
are subject to different and more stringent regulation under the CAN-SPAM Act.
Common Short Codes (CSCs)
Introduced in the U.S. market in October 2003, Common Short Codes (CSCs) are short numeric
codes of five or six digits, compatible across carriers, to which text messages can be sent from a
mobile phone. Wireless subscribers send text messages to short codes to access a wide variety of
mobile content, for example, to vote for contestants on American Idol. Many entities use CSCs to
communicate with interested parties: television stations; individual television shows; radio
stations; instant messaging services; political, advocacy, and other organizations; magazines, and
sports teams—among others. Users send a message to the CSC to subscribe to alerts or other
messages. Sometimes these messages are delivered for free by the originator, sometimes there is a
fee. Figure 2 illustrates how a CSC message is processed.

“Vanity” CSCs are also available (for a higher price)—these CSCs use letters on a mobile device
keypad to spell out words that are easy to remember and are chosen to reflect the service the short
code is being used to access.2 Furthermore, although CSCs can be “compatible” across all
carriers, some CSCs are established as business partnerships between a specific carrier and
another entity. For example, American Idol has an exclusive partnership with AT&T Wireless.3
Issues for Congress
For Congressional policymakers, the major issues that have arisen stem from what could be
called “same problem, different platform.” For example, issues such as consumer fraud and
children’s accessing inappropriate content, which have existed previously in the “wired world,”
have now found their way to the “wireless world.”
Other issues stem from the difficulty in applying technical definitions to a given service, such as
whether a text message is sent “phone-to-phone” or using the phone’s associated e-mail address.
For example, spam sent between two phones or from one phone to many phones does not fall
under the definition of spam in the CAN-SPAM Act of 2003 (Controlling the Assault of Non-

Solicited Pornography and Marketing Act, P.L. 108-187); but if that same message is sent from a
phone or computer using the phone’s associated e-mail address, it does.
Applicability of CAN-SPAM Act to Unwanted Wireless Messages
The CAN-SPAM Act was and is intended to curb the amount of spam that consumers receive in
their e-mail accounts. At the time the act was being considered in 2003, text messaging was in its
infancy as a service. As discussed above, SMS messaging is not the same as messaging that uses
a mobile phone’s associated e-mail address (i.e., 2025551212@carrier.com). At this time, only the
latter type of message is covered by CAN-SPAM; messages that are sent “phone-to-phone”
through the SMSC are not.
There is no evident reason for messages that appear the same to a user and have the same effect
on a user (generally, annoyance) to be treated differently under CAN-SPAM. Resolving this
discrepancy in the treatment of these two types of messages would require a change to the statute.
Inability of Consumers to Disable Text Messaging
Some mobile service customers have expressed frustration to their Congressional representatives
about unwanted text messages and the inability to selectively block or completely disable text
messaging on their phones. While carriers generally offer a range of text messaging packages, for
example, 500 messages for $10, some customers do not use text messaging and, therefore, pay a
small fee every time they receive a message. A number of user discussion sites contain posts from
users who are frustrated with the extra charges they incur from unwanted messages.4 In December
2007, a class-action lawsuit was filed against T-Mobile in this matter.5
Most carriers offer some form of text blocking to their customers. A June 12, 2008, article by
David Pogue in the New York Times6 outlined the various options being offered by different
carriers. The Appendix contains information from that article that may be helpful to consumers.
Given that carriers are beginning to offer various forms of text blocking to their customers, it may
be advantageous to consumers to wait to see what options the different carriers develop. In that
way, competition is given a chance to succeed in this area and carriers are offered the opportunity
to assess what their competitors are doing and perhaps improve their own services. Eventually,
however, Congress may wish to investigate whether customers are being offered the best possible
options to assure that they are not receiving unwanted text messages.
Carrier Blocking of Common Short Code Messages
In September 2007, Verizon notified NARAL Pro-Choice America that it would not participate in
its CSC program. NARAL does not charge for its messages and users may opt-in or opt-out as

desired, but Verizon stated that it does not accept programs from any group “that seeks to
promote an agenda or distribute content that, in its discretion, may be seen as controversial or
unsavory to any of [its] users.”7
This decision was immediately criticized by free-speech advocates, although communications
scholars pointed out that the company most likely, from a legal standpoint, did have the right to
refuse to participate in the program.8 Since text messages are not carried over the traditional
telephone network, such messages are not protected under common carrier regulation. The next
day, Verizon changed its decision and is now participating in NARAL’s CSC program, saying in a
statement that the decision had been “an incorrect interpretation of a dusty internal policy” that
“was designed to ward against communications such as anonymous hate messaging and adult
materials sent to children.” The policy had been developed “before text messaging protections
such as spam filters adequately protected customers from unwanted messages.”9
This issue highlights the difficulty in applying the current regulatory structure to new services.
While mobile providers appear to have the legal right to determine what information is available
through their CSC programs, Congress may wish to consider whether and how political and other
speech might be better protected in those programs.
Deceptive and Misleading Common Short Code Programs
Many third-party content providers use the CSC program and bill the usage through the mobile
service provider. For example, content providers can allow mobile device users to download
content (e.g., ringtones) or participate in SMS-based “chat.” While most of these content
providers are legitimate businesses, others use deceptive tactics to gain customers and run up
unexpected charges.10
For example, as reported by CBS News in February 2008, some customers have subscribed to
monthly services without reading the “fine print” and find that the charge is often difficult to
remove because it is an independent third party rather than the customer’s mobile service
provider.11
The Mobile Marketing Association has developed “Consumer Best Practices Guidelines”12 that it
expects its members to follow. This code includes limiting subscription periods to one month,
after which consumers must re-subscribe, and providing alerts to customers when their chat-
related charges reach $25 increments. Although the best practices have not eliminated all
misleading programs, over time the industry may bring its members into compliance. More

clarity on industry efforts might allow policymakers an opportunity to assess the efficacy of those
efforts.
Protecting Children from Inappropriate Content on Wireless
Devices

As more mobile devices become equipped to access the World Wide Web and additional content
services are made available via CSCs, the risk of children downloading inappropriate content will
likely increase. While carriers may follow a set of voluntary guidelines13 to promote wireless
safety for children, there is no way to guarantee that children will not be able to access
inappropriate content by circumventing carrier-implemented safeguards.
The following types of material can be downloaded on many wireless devices, and may include
content inappropriate for children.
• Images, such as background “wallpaper” for the phone screen.
• Games, including some games that are also available for gaming systems.
• Music and songs, including ring tones, ringback tones, and downloads of full
songs.
• Video, including certain television shows, movies, and music videos, as well as
video programming specially made for, and only available on, wireless devices.14
The wireless industry is working to ensure that children do not access inappropriate information
over their wireless devices, but there is no definitive research on the success of these efforts.
Whether current efforts to protect children from inappropriate content over wireless devices may
be an issue of interest to policymakers.
Mobile Cyberbullying
“Cyberbullying,” harassing communications sent, for example, via e-mail or text messages or
through social networking sites such as Facebook or MySpace, is a growing problem. The issue
made national headlines in November 2007 after the suicide of Megan Meier, a 13-year-old

13 CTIA—The Wireless Association® has voluntary guidelines for wireless carriers to use in classifying content that
they provide directly over wireless handsets. These voluntary guidelines apply only to content that you purchase from
your wireless carrier, either on a one-time use or download basis, or as part of a package with a monthly fee such as
ring tones, wallpaper, games, music, video clips, or TV shows. Content that is generated or owned by a wireless user,
such as text messages, instant messages, e-mail (through chat rooms, message boards, etc.) and picture mail is not
included in the wireless carrier’s content classification system. Also, content that is accessed by surfing the Internet on
a wireless handset is not currently included in the classification system. The guidelines urge carriers to provide separate
Web filtering software for Web browsing services. Wireless carriers choosing to follow these voluntary guidelines
agree to use at least two content ratings: (1) Generally Accessible or available to consumers of all ages; and (2)
Restricted or accessible only to those age 18 and older or to those younger than 18 years old, when specifically
authorized by a parent or guardian. The Restricted ratings system generally is based on or uses criteria under existing
ratings systems for movies, television, music, and games. CTIA Guidelines are available online at http://www.ctia.org/
advocacy/policy_topics/topic.cfm/TID/36.

Missouri girl. In that case, the mother of a former friend of Megan’s set up a fake MySpace page,
pretending to be a boy who had just moved to the area and was home-schooled. Within a few
weeks of becoming “friends” with “Josh,” on October 15, 2006, the tone of his messages changed
drastically, with “Josh” saying he no longer wanted to be friends with Megan, because “he” had
heard that she had been mean to some of her friends. On October 16, 2006, Megan hanged herself
in her closet.
Although, as in the case described above, much cyberbullying takes place in the “wired” world,
more recently, these sorts of messages are being sent from and to mobile devices. Since many
mobile devices are capable of performing the same tasks as computers, these messages are now
being sent via mobile instant messaging, the mobile websites of social networking sites, and text
messaging.
The subsequent public outcry over the Megan Meier case led to four bills being introduced in the
110th Congress, three by Representative Linda Sanchez and one by Senator John Kerry; each
contained language that would have included the use of wireless devices in the definition of
cyberbullying.
• H.R. 3577 was introduced on September 17, 2007, and referred to the House
Committee on Energy and Commerce Subcommittee on Telecommunications and
the Internet; no further action was taken.
• H.R. 4134 was introduced on November 9, 2007; it was passed by the House on
November 13, 2007, and referred to the Senate Committee on the Judiciary on
November 14, 2007.
• H.R. 6120 was introduced on May 21, 2007, and referred to the House
Committee on the Judiciary; no further action was taken.
• S. 3016 was introduced on May 14, 2007, and referred to the Senate Committee
on the Judiciary; no further action was taken.
The bills were substantially similar. All would have defined cyberbullying to include “verbal,
visual, or written psychological bullying or harassment by an individual or group, using an
electronic device or devices including e-mail, instant messaging, text messages, blogs,
telephones, pagers, and websites, to support deliberate, repeated, and hostile behavior that is
intended to harm others.” H.R. 3577, H.R. 4134, and S. 3016 would have authorized $5,000,000
for educational grants to carry out Internet crime prevention education programs from 2008
through 2012; H.R. 6120 would have authorized $10,000,000 for the time period 2009 through
2013.
Disclosure of Text Messages Under Freedom of Information Laws
and the Stored Communications Act15

Text messages are routinely used to conduct government business. As a result employers,
litigants, newspapers, and public interest groups are increasingly seeking access to the contents of
such communications in order to shed light on the workings of government. One of the arguments
against disclosure of text messages emerging from public officials is that certain delivery

Text and Multimedia Messaging: Emerging Issues for Congress

platforms or technological devices should, by their very nature, be private because the official
owns them, or keeps them in her pocket. Because text messaging represents a relatively new form
of electronic communications, state and federal courts are considering requests for access to and
disclosure of text messages pursuant to freedom of information and privacy laws.
Courts have begun exploring ways to apply open government laws to text messages. In Texas, a
state judge ordered the City of Dallas to turn over e-mails and text messages sent by city officials
from personal accounts and personal hand-held devices to conduct city business, and held that the
e-mails and messages were subject to disclosure under the Texas Public Information Act.”16
Newspapers in Detroit, Michigan, filed a Freedom of Information Act (FOIA) lawsuit against the
city seeking disclosure of text messages sent by Detroit elected officials on city-issued pagers that
relate to the city’s $8.4 million settlement of two whistle-blower lawsuits brought by former
Detroit police officers.17 The city has argued that disclosure of the text messages would violate
the federal Stored Communications Act. A public records directive issued by the city states that
all electronic communications sent on city equipment “is not considered to be personal or
private.”18 Although the newspapers obtained the text messages through an anonymous source,
they continue to press for the release of additional information under public records law.19 A court
ruled part of the information the newspapers wanted was public, the Free Press published text
messages related to the cover-up and the Mayor and Chief of Staff were charged with eight
felonies.20 The newspapers are continuing to pursue additional information using the state FOIA.
New York legislators worked to revise the state’s open records law to specifically add text
messages to the list of records covered.21 A new Freedom of Information Law became effective in
New York on August 7, 2008, and includes provisions which reflect a recognition of advances in
information technology, but does not include a provision on text messaging.22
Subject to certain exceptions, the Stored Communications Act (SCA), which is part of the
Electronic Communications Privacy Act, bars “a person or entity providing an electronic
communications service to the public” from knowingly divulging to any person or entity the
contents of a communication while in electronic storage by that service.” The SCA distinguishes
between two types of providers: “remote computing services” and “electronic communications
services.”

Text and Multimedia Messaging: Emerging Issues for Congress

Courts have been examining whether the disclosure of text messages sent by employees on
employer-issued pagers violates the privacy rights of employees, and whether such disclosure is
barred by the Stored Communications Act.23 The Ninth Circuit Court of Appeals recently held
that the city employer violated the constitutional rights of an employee when the employer
reviewed text messages sent and received by the employee on his employer-provided pager. The
court of appeals also held that the text-messaging service provider violated the federal Stored
Communications Act by giving the city transcripts of the text messages. In Quon v. Arch
Wireless,24 the Ninth Circuit held that a city’s text message provider was an electronic
communications service for purposes of the act because it enabled city employees to send and
receive wire communications. In Quon, city employees sued their employer after they were fired
for using their employer-provided mobile devices for personal communications.
Using SMS to Support Law Enforcement and Emergency Response
In April 2008, the FCC adopted rules for the Commercial Mobile Alert System (CMAS), which
will deliver emergency text messages to the public during emergencies and natural disasters,25
and recommended that the Federal Emergency Management Agency (FEMA) be the program’s
aggregator. The program was mandated by the Warning, Alert and Response Network Act that
was signed into law in 2006.26 Under this law, the FCC was required to develop plans for a
commercial mobile-alert system through which wireless carriers would voluntarily transmit text
messages sent out by the government. The FCC has divided the types of messages the
government will send out to mobile-phone users into three broad categories:27
• Presidential Alerts deal with national emergencies and will take precedence over
any other impending alerts
• Imminent Threat Alerts deal with emergencies that may pose an imminent risk to
people’s lives or well-being.
• Child Abduction Emergency/AMBER alerts will be related to missing or
abducted children.
In addition, the FCC says that all subscribers with roaming agreements will receive timely alerts
“provided the subscriber’s mobile device is configured for and technically capable of receiving
alert messages from the roamed upon network.”28

Text and Multimedia Messaging: Emerging Issues for Congress

The architecture adopted by the FCC calls for a centralized alert-aggregator where federal and
state emergency-response agencies would send their warning messages to be authenticated and
dispersed to the appropriate participating commercial mobile services. Noting FEMA’s role in
developing the proposal for the adopted architecture, the FCC recommended the agency as its
first choice to serve as the alert aggregator and FEMA has accepted that role
The FCC has issued a Second Report and Further Notice of Proposed Rulemaking;29 an Order on
Reconsideration and Erratum;30 and a Third Report and Order.31 Of particular note, in the Third
Report and Order, the FCC—
• adopted notification requirements for wireless providers that elect not to
participate, or to participate only in part, with respect to new and existing
subscribers;
• adopted procedures by which wireless providers may elect to transmit emergency
alerts and to withdraw such elections;
• adopted a rule governing the provision of alert opt-out capabilities for
subscribers;
• allowed participating wireless providers to recover costs associated with the
development and maintenance of equipment supporting the transmission of
emergency alerts; and
• adopted a compliance timeline under which participating wireless providers must
begin CMAS deployment.
At this time, the technical standardization process at FEMA is not yet complete and CMAS is,
therefore, not operational.
Congressional and Industry Response to
SMS-Related Issues

The issues discussed in this report have prompted different levels of response from Congress and
the wireless industry:
• Issues that are being addressed by industry, so policymakers may wish to wait
and see how those efforts play out;
• Issues that have not risen to a level of priority in Congress, but would require
statutory action to effect change; and
