software
The USB modem is designed to provide a wide range of capabilities
using CDMA and WiMAX network technology. Implementation of
these features depends on the particular service provider and
account features you have chosen.
AirCard 250U Modem - User Guide
Some features described in this manual may not be supported by your service
provider or may not be available with your network account. For details of the
services and accounts available, contact your service provider.
Wireless modem
Once installed and configured, the modem can connect to the CDMA network or
WiMAX network automatically. You just insert the modem, allow Watcher to
autolaunch and authenticate your account on the network, then launch your
Internet browser (which you can also configure in Watcher to launch
automatically)—you’re online!
Alternatively, you can make a high-speed data connection without running
Watcher—simply by launching whatever application you want to use (such as
your web browser or e-mail application). For details, see the online help topic
“Autoconnect behaviour”.
The modem also allows you to dial up a modem (such as a corporate server).
TRU-Install
TRU-Install™ is a Sierra Wireless feature that installs the necessary software and
drivers the first time you insert the modem into your computer. An installation CD
is not required.
TRU-Locate
With TRU-Locate™, you can use location-based services (GPS) to query, for
example, the network for information on points of interest (POI) that are near your
current location, or display driving instructions.
Note: TRU-Locate is subject to feature availability.
Your modem requires an unobstructed view of GPS satellites (in the sky), and,
like any other GPS device, might not perform well within forested areas or near
tall buildings.
Depending on your account, you may be charged for each position fix or after you
have performed a certain number of fixes. For details, contact your service
provider.
Depending on the mechanism that the network and your modem use to obtain
location information, GPS may not be supported:
• If Network Mode is set to “EVDO Only”
• If you're roaming
• If you do not have network coverage
• Due to other reasons.
If you’re having problems using GPS, contact your service provider.
10 2131331
CDMA 3G services
The modem can operate over a type of wireless network called CDMA (Code
Division Multiple Access).
CDMA 3G technology provides a variety of connectivity features, depending on
your service provider and account:
• 1x-EVDO Rev. A supports Internet connections with data rates up to
3.1 Mbps (downlink from the network) and 1.8 Mbps (uplink to the network).
Average data rates are 450-800 Kbps (downlink from the network) and
300-400 Kbps (uplink to the network). Actual speed depends on the network
conditions.
• 1x-EVDO Rev. 0 supports Internet connections with data rates up to
2.4 Mbps (downlink from the network) and 153 Kbps (uplink to the network).
Average data rates are 400-700 Kbps (downlink from the network) and
40-80 Kbps (uplink to the network). Actual speed depends on the network
conditions.
• 1X supports Internet connections with data rates up to 153 Kbps. Actual
speed depends on the network conditions.
Once the connection is established, you can open your browser and connect to
any web site that is accessible through the Internet, or access other Internet
services (such as e-mail).
The connection is “active” when data transmission is occurring. If data
transmission stops for a period of time (determined by the network), the
connection becomes dormant.
• Circuit switched (dial-up) data, using the earlier CDMA IS-95 specification,
supports data connections to any dial-in service at rates up to 14.4 Kbps.
• QNC (Quick Net Connect) provides a simplified way to dial into an Internet
connection (using circuit switched data) where 3G (1xEV-DO or 1X) highspeed packet service is not available.
• SMS (Short Message Service) allows you to send and receive short text
messages using the modem.
Watcher auto-update
Choose to have the latest features and updates for your modem and Watcher
software installed automatically. Easily set your own preferences for when
updates are downloaded. Set a schedule that automatically checks daily, weekly,
monthly or not at all. Updates can be over Ethernet or WiFi to save WWAN
overlimit or roaming charges.
• Keeps your firmware, drivers and Watcher software up to date.
• Allows you to set a specific schedule that can be set to check for updates
such as daily, weekly, monthly or not at all.
• On demand manual checks can also be completed.
• A download pause-and-resume capability pauses the update download when
your computer is in use and resumes it during idle time so the user
experience isn’t affected.
• Updates can be over any connection—not just the WWAN connection.
Rev 1.0 May.10 11
AirCard 250U Modem - User Guide
Additional features of the modem
Beyond the features of the CDMA network and WiMAX network, the modem
provides additional software features:
• PIN security code to protect your modem and account from unauthorized use.
• A wizard to assist with activating your CDMA account.
• Sound options to customize ringtones for SMS messages.
• A Call Log to track outgoing calls and determine the amount of data trans-
ferred.
Package contents
Your package contains the following items:
• AirCard 250U modem
• Quick Start Guide
• Carry pouch
To install the modem drivers and software, you do not need an installation CD.
Your modem uses the Sierra Wireless TRU-Install feature. The drivers and
software are installed when you insert the modem into your computer and go
through the software installation; an installation CD is not required.
System components
Your modem is just one part of a system designed to provide you with a wide
range of communication features. Every component of the system is needed to
enable these capabilities.
Your host computing device
Your notebook or desktop computer hosts the modem hardware and runs the
communication software: your web browser or e-mail application, and Watcher—
the enabling software for the modem.
You may also have other software on your computer that can be used wirelessly
with the modem, such as: file transfer applications (FTP), chat or instant
messaging, a VPN (Virtual Private Network) client, client software for a corporate
server application.
The USB modem
The modem provides your computer with a connection to the CDMA or WiMAX
wireless network.
The modem fits into a USB slot available on most notebook and desktop
computers.
12 2131331
Every CDMA network operates on one of three radio frequency bands. As a dualband product, the modem operates on two of these bands (see page 32),
providing a wide coverage area.
The modem drivers and enabling software
The modem drivers and enabling software (Watcher) monitor and manage your
wireless connections.
Your modem uses the Sierra Wireless TRU-Install feature—the drivers and
software are installed when you insert the modem into your computer.
The device driver software enables the modem to work with your computer’s
operating system.
Using the Watcher software, you can manage the modem and monitor your
connections.
For step-by-step instructions to access features of Watcher, use the application’s
online help.
CDMA service provider account
Companies that operate CDMA networks and provide access to these networks
are called service providers. To use the modem, you must have an account with a
CDMA service provider.
Note: You can use the
Lock Modem feature to
prevent others from using
your account, should your
modem be stolen.
Note: More information
about CDMA networks is
available on the CDMA
Development Group web
site,
www.cdg.org
.
Each service provider has its own pricing options. There may be flat rate
accounts, which provide you a maximum number of minutes of network usage for
a fixed monthly fee. There may be accounts for which you are charged for
network usage by the minute or by the amount of data transmitted.
Your account may include a variety of other services such as SMS messaging or
location-based services.
Each modem has been provisioned at the factory for use with a particular service
provider. This sets the modem to use particular radio channels and enables
services specific for that provider.
The process of setting up your account is called activation. Activation involves
action by the service provider and configuration of the modem.
The procedure to configure (activate) your modem is covered in Activation on
page 21.
The CDMA wireless network
This is the worldwide infrastructure providing the radio coverage that allows you
to stay connected. Made up of radio towers and a variety of network switches,
routers, and servers, the network is an interconnection of many service providers.
Rev 1.0 May.10 13
AirCard 250U Modem - User Guide
Note: Most service
providers have coverage
maps on their web sites.
Note: The fee for service
is usually higher when you
are roaming (connecting to
a network other than the
one belonging to your
service provider).
There are CDMA networks that operate in the frequency bands supported by the
modem throughout North America and parts of Latin America, Asia, and New
Zealand. However, each service provider operates a network that covers a limited
geographical area within the overall CDMA coverage area.
Most service providers have “roaming” agreements with other service providers,
so that they can offer service outside of the coverage area of their own networks.
For example, assuming you live in Vancouver (Canada), and travel frequently to
Seattle (United States), you can obtain an account with a Vancouver service
provider that has a roaming agreement with a service provider in Seattle. You
would then have local service in Vancouver, and roaming service in Seattle.
Care and maintenance of your modem
As with any electronic device, the modem must be handled with care to ensure
reliable operation. Follow these guidelines in using and storing the modem:
• The modem should fit easily into your USB slot. Forcing the modem into a slot
may damage connector pins.
• When inserting or removing the modem, always grip it by the sides rather
than the end.
• Protect the modem from liquids, dust, and excessive heat.
• When not installed in your computer, store the modem in a safe place.

2: Getting Started
• The AirCard 250U
software
• Account activation
and configuration
Before you can begin using the modem, you must:
1. Insert the modem, to install the enabling software and drivers.
2. Activate an account and configure the modem to use your
account (unless the modem has been pre-activated).
This section provides an overview of this process.
The AirCard 250U software
The modem comes with the following software:
• Watcher application that you use to manage the modem and
monitor your connections on your computer
• The driver software that provides the interface between the
modem and your Windows operating system
Detailed instructions for installing the modem and its software are
provided in Installation on page 17.
Account activation and
2
configuration
To use the modem, you must have an account with a CDMA or
WiMAX service provider. The process of setting up an account is
called activation.
If you purchased the modem directly from a service provider, you
may already have an account; your modem may be pre-activated.
Otherwise, run the Watcher software and the Activation Wizard,
which guides you through the activation and configuration process.
(Depending on your configuration, the software and the activation
procedure may start automatically.)
Configuring the modem involves setting the phone number assigned
by your service provider and may involve entering other network
parameters and settings such as a user name and password to
access services.
Your service provider may need to know:
• The billing information to use to collect payment for your network
usage.
• The ESN (Electronic Serial Number) or MEID (Mobile Equipment
Identifier) assigned to your modem during the manufacturing
process. (The ESN or MEID is printed on a label on the modem
Rev 1.0 May.10 15
AirCard 250U Modem - User Guide
and can be displayed in the software.) This number is used to help authenticate your account when you connect for service.
You require from your service provider:
• An activation code that gives you access to configure the account.
• A phone number for your modem.
• Additional information specific to your service provider such as:
· A user ID (username) and password to authenticate your network
connection.
· A SID (System IDentifier) that identifies your home network area and is
used together with your phone number to determine if you are “home” or
“roaming”.

Watcher is the application that allows you to manage and monitor the
connection between the modem and the CDMA (3G) or WiMAX (4G)
network. You use Watcher to:
• Determine your signal strength, roaming status, 3G/4G high-
speed data availability, and other network connection parameters
• Initiate and end data calls
• Use location-based services (subject to feature availability)
• View call statistics
• Receive and send SMS messages
• Customize features and options
Depending on Watcher settings, you may be able to connect to the
CDMA or WiMAX network without starting Watcher—simply by
launching whatever application you want to use (such as your web
browser or e-mail application); for details, see the online help topic
“Autoconnect behaviour”. However, Watcher and its icon in the
system tray won’t be available for you to monitor the status of the
