Back in January, we at AWARE compiled a list of resources provided by wireless carriers on the Commercial Mobile Alert Service (CMAS), including lists of CMAS-capable devices sold by each carrier. Since then, the rollout of CMAS (also known as Wireless Emergency Alerts, or WEA) has begun, and, not surprisingly, participating carriers have provided more information to customers on the system, as well as updated lists of handsets that will be able to receive a CMAS message.

CTIA has published a helpful collection of information from several participating carriers. Below are links to each carrier’s page on CMAS/WEA, as well as a listing of available CMAS-compatible devices, if the carrier has published these.

AT&T’s website provides an FAQ on CMAS. Capable devices are listed below; the carrier also states that it will be working to bring more CMAS-capable devices on during 2012:

• Samsung Galaxy SII (SGH-i777)
• Samsung Captivate Glide (SGH-i927)
• Motorola Atrix 2 (mb865)

Cellcom’s website provides an FAQ with background on CMAS. (If you are not familiar with Cellcom, they are a regional carrier offering coverage in Wisconsin and Michigan.) Cellcom currently offers one CMAS-capable device: the Motorola Milestone X2. The carrier states that “as new devices are launched, we will specify if the device is WEA capable.”

Cricket’s website offers a brief FAQ on CMAS. The page includes a link to a list of CMAS-capable devices; however, this page was not operational when we conducted our research. If you are able to access this information, please let us know.

Sprint’s website provides a host of resources on CMAS, including information on the New York City test back in December 2011. CMAS-capable devices include:

• Sanyo Inuendo
• Sanyo Vero
• Sanyo Milano
• HTC EVO 3D
• Samsung Galaxy SII 4G Touch
• LG Marque
• Kyocera DuraMax
• Kyocera Duracore
• Kyocera Brio
• Samsung Trender
• HTC EVO Design 4G
• Samsung Transform Ultra

T-Mobile’s website offers a list of FAQs on CMAS. And as we reported back in January, the site has included a “CMAS” feature checkbox on its phone shopping page, so customers can compare CMAS support alongside other features they might be interested in such as QWERTY keyboards or 4G. CMAS-capable handsets at T-Mobile include:

• LG DoublePlay
• Nokia Lumia 710
• T-Mobile MyTouch (including models Q and 4G)
• Samsung Galaxy S

US Cellular provides one of the more extensive FAQs on CMAS, and currently offers three CMAS-capable devices:

• Samsung Character R640
• BlackBerry Curve 9350
• BlackBerry Torch 9850

Verizon’s website offers an FAQ on CMAS and states that it currently offers CMAS in New York City and Washington, DC. Its CMAS-capable devices include:

• Droid 2 Global by Motorola
• Droid Pro by Motorola
• Droid X2 by Motorola
• Motorola Citrus
• LG Cosmos 2
• LG Revere
• LG Enlighten

It should be noted that while these carriers combine to cover the vast majority of the U.S., there are 123 total carriers of various sizes that have opted to carry CMAS messages, according to the Federal Communication Commission’s latest registry of CMAS carriers (available here – links to a spreadsheet).  It seems less information is available from these carriers on which handsets can receive CMAS messages. If you have seen CMAS information from one of these carriers, please let us know.
