Updated Feb. 5, 2005 to add GSM versions for Cingular, AT&T
Wireless and unlocked version.
Updated May 11, 2005 to add the Verizon Wireless version.
Discontinued: Check out our review of the Palm Treo 700p which replaces the Treo 650 on Sprint and Verizon in June 2006 and the Treo 680 which replaces the Treo 650 on Cingular in November 2006. And the Windows Mobile Treo 750 on Cingular, as well as the Treo 700wx on Sprint and Verizon might be of interest.
One of the most anticipated PDA phones of the
year, the Palm Treo 650 is the hottest Palm OS smartphone on
the market. Following on the heels of the very successful Treo
600, the Treo 650 adds
several key improvements that address the needs of road warriors
and improvements in technology since the release of the 600 over
a year ago. Sprint was
the first US carrier out the door with the 650, and GSM versions
for Cingular, AT&T Wireless as well as an unlocked version
for use with any GSM carrier were released early Feb. 2005. We'll
take an in-depth look at the Sprint, Cingular and unlocked offerings
in our review.
The Treo 650 is both a cell phone and a full-featured
Palm OS PDA. The Sprint version runs on their CDMA network in the
US and supports PCS Vision (1xRTT for high speed data). The Verizon
version, released on May 11, 2005 also supports 1xRTT for data.
The GSM version is currently available in three flavors for Cingular,
and an unbranded, unlocked version. The Cingular and AT&T Wireless
versions are locked to their respective carriers, so you'll need
to purchase the more expensive unlocked version directly from Palm
if you wish to use the phone with other carriers. All GSM flavors
are quad band 850/900/1800/1900MHz world phones with GPRS and EDGE
for data. While most mobile phones with full-featured PDAs make
concessions to phone ergonomics or PDA ergonomics and features,
the Treo manages to do it all and do it well. It's easy and comfortable
to use one-handed as a phone and has all the features of a current
generation Palm OS 5 PDA. The integrated thumb keyboard makes it
a great choice for those who need to write emails on the go. Though
larger than today's feature phones, the Treo is still pocketable
and smaller than competing Pocket PC phones.

Much looks the same on the Treo 650 which uses the
same basic casing as the Treo 600, but looks can be deceiving. While
the 650 is an evolutionary rather than revolutionary device, it adds
several key features that broaden the device's appeal and will lead some
Treo 600 users down the upgrade path. The Treo 650 has an absolutely
lovely 320 x 320 pixel transflective color display that puts the Treo
600's 160 x 160 passive matrix display to shame. What high end mobile
phone would be complete without Bluetooth? The 650 has Bluetooth with
support for headsets, HotSyncing and file transfer. On June 16, 2005,
Sprint and Palm released a ROM update which adds support for Bluetooth
DUN (dial up networking), which you can download here.
Though the Cingular version's manual includes instructions and screen
for DUN, the feature is also disabled on their phone. The unlocked
GSM Treo 650 available directly from Palm has DUN enabled. If you
wish to use DUN with the unlocked version, refer to Palm's guide for
instructions. The guide can be found at www.palmone.com/us/support/handbooks/treo/Treo650_GSM_DUN_UG.pdf.
DUN works very well on our unlocked Treo when testing with a BT enabled
notebook and even an iPAQ hx4700! If you
are using the Treo with a Pocket PC for BT DUN, you'll need to use a
terminal window on the Pocket PC to establish the connection. Note that
you can't use data apps such as Web and VersaMail while the Treo is in
Another must is a user-replaceable battery and the
Treo 650 has one. The camera software is greatly improved and the 650
takes much more natural and pleasing photos than the 600 and many other
VGA camera phones. MP3 fans will be happy to know that you can use standard
stereo headphones if you purchase an optional adapter. To top it off,
the Treo 650 is the only Palm OS (or Pocket PC for that matter) smartphone
that uses non-volatile memory for storage. This means your programs and
data will survive even if the battery drains completely. Excellent!

Features at a Glance
The CDMA Treo 650 runs on Sprint's cellular network
in the US with support for the 800 and 1900MHz digital bands and uses
1xRTT for data offering average speeds of 75k - 100k. The GSM version
is a quad band phone that will work anywhere in the US where GSM is available.
It has both GPRS and EDGE for data. EDGE offers speeds that rival 1xRTT
on CDMA networks and yield ~75 - 100k download speeds.
It runs Palm OS
Garnet (5.4.5) on a 312MHz Intel XScale processor and has 23 megs of
available memory. The device has Bluetooth, a VGA digital camera and
a backlit thumb keyboard. As noted, it has a 320 x 320 color display,
and it has an SD slot that supports SDIO. Like prior Treos, but unlike
Palm OS PDAs, the Treo 650 doesn't come with Graffiti handwriting recognition
software. Instead you'll use the keyboard to enter and edit text. You
can use the touch screen and included stylus for navigation, selecting
items and highlighting text.
In the box you'll find the phone, battery, stylus,
world charger, software CD, 350 page printed manual (for Sprint), 204
page printed manual (for Cingular and AT&T Wireless), mono headset and
a sync cable.
Design and Ergonomics
The Treo 650 uses the same industrial design and basic
casing found on the Treo 600. As Palm noted, why mess with a good
thing? Though large by feature phone standards, it is by no means a gargantuan
phone and is much smaller than Pocket PC Phone Edition devices. Those
who want full PDA features including a large touch screen and a thumb
keyboard, know that these can't be cramped into a tiny device without
losing out on PDA features or usability.
Above: Sprint version side view.
Below, Cingular version.
The phone feels great in the hand with gentle curves
that fit just right. The Sprint version's plastic casing is predominantly
metallic blue-gray with silver and chrome accents. The Cingular version
is silver with a mid-blue metallic screen surround. The Treo does have
an antenna nub that sticks up about one third of an inch from the top
left corner. Gone is the dedicated power button found on top of the Treo
600. Instead the 650 uses a dual purpose call end/power button, but leaves
the much-loved ring silencer slider button intact on top of the phone.
As you'd expect, the phone's earpiece speaker is located
above the display and the mic is located on the bottom right edge. The
speaker for system sounds and the speakerphone is located on the back
side. Why is that speaker on the back? So you're not deafened if you
accidentally enable speakerphone or if alarms go off while in a call.
As with most phones, the volume up/down rocker is located on the left
side, but unlike most phones, you'll hit the button just below to confirm
the volume change. When not operating the volume rocker, that button
launches Real Player. There are no controls on the device's right side,
and the sync, charge and headset port are located on the bottom edge.
The SD slot is located up top, as is the IR window and the afore-mentioned
silencer switch. The VGA camera lens and self-portrait mirror live on
the back of the phone as does the battery door.
The Treo has dedicated call send and end buttons just
below the display surrounding the directional pad. The call end key doubles
as the power switch for the mobile phone radio and can also turn/off
the PDA screen. Thankfully, you'll also find dedicated Home and Menu
buttons below the display which is a much better solution than embedding
them in the keyboard. Lastly, the device has dedicated Calendar
and Messaging buttons below the display in the d-pad zone. If you wish,
you can re-assign the applications of your choice to all except the call
send and end buttons. Speaking of d-pads, the Treo has a superb 5-way
directional pad that's easy to operate one-handed and is very responsive
The Treo 600 keyboard was quite successful but that
didn't stop Palm from making some minor improvements. The keyboard
still features the same radial design with the keys curving in a subtle
smile, but the keys now require less pressure and have been flattened
a tad, meaning your fingers are less likely to roll off the key while
typing. The backlighting is now impressively bright with most keys having
strong white backlighting that contrasts with the painted black letters
and the embedded number keys having blue backgrounds with bright white
illuminated letters and numbers. For some, the keys may actually be too
bright for use in very dark environments. The Treo has a full QWERTY
keyboard with embedded numbers that contrast easily for dialing. When
the phone dialer screen is open on the display, the device uses the embedded
numbers rather than the letters on the dual-purpose keys for dialing.
As with a desktop keyboard, the shift key capitalizes. A dedicated Fn
key activates common punctuation and symbols superimposed on the keys
and the Alt key brings up a pop-up list of additional symbols available
for a key. The keyboard has both left and right shift keys, and an elongated
space bar making for faster and easier typing.
Horsepower and Performance
While some smartphones make concessions in processing
power, the Treo 650 has the latest, greatest Intel PXA270 "Bulverde"
processor running at 312MHz. While that processor speed doesn't sound
impressive compared to some recent Pocket PC offerings, Palm OS 5 has
much less overhead and requirements than Windows Mobile and that processor
running at 312MHz is pretty much state of the art and all that you'll
need for a Palm PDA unless you're seriously into game emulators or videos
encoded at very high bitrates (over 500 kbps) by mobile standards.
The Treo 650 is the first Palm OS smartphone to use
persistent memory for storage (NAND flash ROM rather than RAM). Flash
ROM doesn't require power to maintain its contents, so PDA and phone
data won't be lost even if the battery runs completely dry. Excellent!
What are the drawbacks? NAND is a bit slower than RAM so applications
take a hair longer to launch and the file system Palm used is less
efficient in terms of space. This means that a very small file will take
up more storage space on the Treo 650 than the Treo 600 so if you're
upgrading from a chock-full Treo 600, you'll find that all of your programs
and data won't fit. PalmOne is working on improving the file system's
efficiency so we may (no promises) see an update that reduces block size
which means very small files won't take up lots more space than they
Of course, you need not store all your programs and
data on internal memory. The 650 has an SD slot so you can add memory
by purchasing SD memory cards. Cards are the perfect place to store large
files such as movies, MP3s and photos. The SD slot supports SDIO, which
is required to use SD networking cards and SD GPS. Currently, Palm's
SD WiFi card does not support the Treo, so there's no way to add WiFi.
Phone Features, Reception and Internet
The phone interface has changed little from the Treo
600, but the buttons and controls have a more sculpted 3D look. You can
launch the phone application by pressing the call send button or selecting
phone from the home screen launcher. This brings up an on-screen dialer
whose buttons are large enough to be pressed with fingers. Handy launchers
for Contacts, Voicemail, Call Log and web browser live below
the buttons on the phone screen. Press down on d-pad to bring up the
full palette of apps, similar to the Favorites concept in IE. You can
have five pages of these favorites and customize them as you see fit.
This makes one handed operation a breeze: simply leave the Treo in the
phone application and you can launch most any app using the d-pad.
Of course the Treo supports dialing directly from your
contacts list and it has speed dial, though it doesn't come with a voice
dialing application. On the Sprint version, we noticed one odd quirk:
when dialing a number using the on-screen dialer, keyboard or from contacts
there' s a few seconds delay before the phone actually dials
the number. The Cingular GSM version doesn't have this quirk. If you've
dialed a number that's not in your contact list or received a call not
in contacts, the Treo will ask you if you'd like to add it to Contacts.
The phone screen shows signal strength, date, time,
E911 location services status (Sprint only) and the battery level. Speaking
of signal strength, both the CDMA and GSM Treos have excellent RF
and held onto a signal even in poor service areas where other phones
lost service. Incoming and outgoing voice quality and volume levels are
very good, even when the signal is at one or two bars. Data connections
were reliable and we got an average of 80k using Sprint's PCS Vision
data network and about 85k using Cingular's EDGE data service.
The Treo comes with Blazer 4.0, which is a reasonably
fast web and full-featured browser. While it doesn't rival the desktop
browsing experience, you'll be able to view most all sites. Blazer offers
two ways to view web pages, one of which is "optimized", which
fits everything to the width of the display so you won't have to scroll
sideways. You can also view web pages unoptimized in "Wide Screen
Mode" to get a more desktop-like rendering of sites, but you will
SSL, frames, bookmarks and cookies but doesn't support plug ins such
as Macromedia Flash. It also supports dialing phone numbers on web pages
and downloading of applications from sites that offer Palm OS software.
For mail, the Treo comes with Palm's VersaMail which
supports multiple email accounts, POP3, IMAP and Exchange ActiveSync.
You'll also get an SMS and MMS application called Messaging which supports
SMS messages and also emails when used in conjunction with Sprint's PCS
Business Connection software and service and your company's Exchange
Server. The Cingular version offers Cingular's Xpress Mail Service which
allows you to set up one or more email accounts for delivery to your
PalmOne tells us the Treo 650 uses the same
camera hardware as the Treo 600, but the software has been revised
heavily to improve image quality. While I was skeptical that
software could improve any CMOS VGA camera's picture quality
all that much, the 650 pleasantly surprised me with some of the
best photos I've seen from a VGA camera phone. In fact, they
rival Nokia's VGA offerings, generally the best in the industry,
though the newest Nokias still win on sharpness. The camera deals
well with bright light, contrasty settings and renders colors
naturally without a great deal of color fringing or the bizarre
color shifts witnessed on some other VGA cameras. While VGA images
are too small for print, they are good for web pages and the
images are sufficiently sharp so as to not require size reductions
to make them usable. Good going, Palm!
The viewfinder fills almost the entire display
with a few controls located at the bottom edge and it updates
quickly as you move the phone. These controls allow you to set
the zoom level (1x or 2x), quickly switch to the photo album,
switch between still photos and videos, set the file save location
and resolution (640 x 480 or 320 x 240). Once you take a photo
or video, you can add voice annotations (for photos), save, delete,
MMS or email the file. Effect and manual adjustments are kept
to a minimum and the camera will always use automatic white balance
and contrast and offers Normal plus Black & White and Sepia
for photo and video effect settings. You can disable the shutter
sound and turn on/off photo review. Videos resolutions are 320
x 240 and 176 x 144 and you can record audio with video. Photos
are saved as JPEGs and videos as .3g2 and Palm includes their
Pics & Videos application to view these as well as manage
and create albums.
Display and Sound
The Treo has a 320 x 320 pixel transflective
display capable of displaying 65,000 colors. It's an excellent
display that's bright, crisp and has excellent color saturation
and balance. It's perfect for viewing photos and videos, and
is sharp when viewing text. The display is viewable outdoors
and washes out just a bit but remains very readable.
Want to listen to MP3s? The Treo supports stereo
output through headphones but sadly comes with only a mono earbud
headset with mic. We tried the 2.5mm stereo headphones included
with the Audiovox SMT5600 MS
Smartphone and they worked fine for phone calls and stereo MP3
playback. PalmOne sells an optional adapter so you can use stereo
headphones with the Treo for music and video playback. Sound
quality is good for MP3 playback using the included RealPlayer,
though not the best we've heard on a PDA.
The Treo comes with a large selection of ring
tones, and ring volume is excellent. You can record your own
ring tones using the Treo's recorder; which is a very simple
process. Speaking of recording, you can send voice notes using
the Messaging app which can be sent via MMS. Oddly, the 650 lacks
a dedicated voice recorder app for recording voice notes on the
fly. Call volume through the built-in earpiece is adequate but
like most recent mobile phones, isn't really loud enough for
noisy environments. It's fine for the home and office, but
busy cafeterias or convertible cars with the top down will send
you running for the included headset or a Bluetooth headset.
The Treo has an integrated Bluetooth class
2 radio and supports headsets and HotSyncing over Bluetooth.
As mentioned, Sprint told us that they did not intentionally
disable DUN (dial up networking) which allows you to use the
Treo as a wireless modem over Bluetooth for your notebook, desktop
or PDA. Rather, Palm couldn't get the driver ready for the
Treo 650's aggressive release date, so Sprint will offer the
Bluetooth DUN profile in a software update (sorry, no ETA). In
the meanwhile, you can get a free and reasonably functional DUN
hack from www.shadowmite.com.
Shadowmite is an active member of the TreoCentral.com
The Cingular and AT&T Wireless versions
are also missing DUN. Ironically, the included manual has
instructions and screen shots covering DUN. Goodness! The manual
states that when DUN is enabled you won't be able to use data
directly on the Treo. That's not much of a hardship since most
of us won't be needing both simultaneously but you will need
to remember to turn DUN off when you no longer need it so the
Treo can connect to the Internet for email and web browsing.
However, since DUN is disabled on the Cingular and AT&T versions,
that point is moot. The unlocked GSM Treo 650 does have DUN,
and it works quite well. EDGE speeds are a treat and the Treo
makes a fast wireless modem. Palm has a short PDF guide for setting
up Bluetooth DUN for Windows PCs here.
When you enable DUN, the Treo warns you that you won't be able
to use the Internet on the Treo itself, just as the manual states.
Once you disable DUN, you can of course use Web, VersaMail and
any other Internet apps you have installed on your PC.
As with most Palm devices, Bluetooth is
easy to set up and use. The device's Bluetooth app asks you what
you'd like to connect to (headset or HotSync to a computer),
then leads you down the path to pairing heaven. We had absolutely
no troubles pairing with headsets and syncing over Bluetooth.
The Treo 650 doesn't have phenomenal range with headsets, but
did get about 8 to 10 feet of distance with most we tested. A
notable exception was the Jabra
BT110 which got only a 3 foot
range with the Treo. The Plantronics
M3500 worked well, as did
the Jabra BT250.
Motorola's new HS820 got
about 8 feet of range with the Treo. PalmOne's own Treo Headset
works very well, with reliable call hand-off, good volume and
good range by Treo standards. We did notice that the GSM version
added about 2 feet to the usable range for headsets.
Both CDMA and GSM Treos have more static and
lower range compared to other Bluetooth enabled mobile phones.
And Palm only supports the more feature-rich Handsfree profile
for a select number of headsets, even though most Bluetooth
headsets have the Handsfree profile these days. Check Palm's
web site for more information.

This unit has very good battery life by powerful
smartphone standards. Though battery capacity remains unchanged
from the Treo 600, Palm claims to have improved power management
to extend battery life. Indeed, our Sprint unit ran for three days
on a charge with light to moderate use and lasted two days with
relatively frequent use including one hour of talk time per day,
eBook reading, gaming, checking emails ten times per day, surfing
the web for 30 minutes, and working with Word and Excel documents
as well as looking up contact and calendar items. The Cingular
version didn't last quite as long and we had to charge it very
two days with moderate use. If you have the phone check email every
15 minutes, you'll need to charge it nightly. Leaving Bluetooth
turned on didn't have a major impact on battery life and we only
saw the expected moderate drain when actively using Bluetooth with
a headset for calls. The 650 has a user replaceable 1,800 mAh Lithium
Ion battery that lives under a door on the back of the phone. That's
a large capacity battery by phone standards, and only the HP
iPAQ 6315 Pocket PC phone equals it.
Do you hate it when your phone accidentally dials
because a button has been pressed while the device is riding in
your pocket? The Treo has a keyguard feature that allows you
to prevent accidental button presses from turning on the unit.
You can set it to automatically lock the buttons when the unit
powers off or after a specified period of time. Pressing the call
send/end keys or application buttons will awaken the display and
it will tell you to press the center action button to turn off
keyguard. Even if you don't use keyguard, only the call send and
end buttons will turn the unit on, making it less likely that accidental
key presses will wreak havoc.
The Treo runs Palm OS 5.4.5 (aka Garnet) and
comes with Palm Desktop 4.1.4 for Windows and Mac with support
for syncing to Outlook on Windows. You'll get Documents To Go 7
for viewing and editing Word and Excel docs and viewing PowerPoint
files, Blazer 4.0 web browser, VersaMail, Messaging for MMS and
SMS, Handmark Solitaire, eReader, Zap!2016, Tetris and a 30 day
trial of the excellent Handmark Express. PalmOne's Camera, Camcorder
and Pictures & Video applications are included for shooting
photos, videos and viewing them on the handheld. The Verizon version
includes Verizon's Wireless Sync software.
Looking for a convergence device that gives you
the best of both worlds? The Treo 650 should be on your short list.
While larger and heavier than today's feature phones, you won't
have to carry two devices so you'll ultimately lighten your load.
The phone has great looks and ergonomics, a thumb keyboard that
makes real work possible and fast Internet access courtesy of Sprint's
PCS Vision service (CDMA) and EDGE service with Cingular / AT&T
Wireless (GSM). We only wish the 650 had integrated WiFi or a way
to add it.
Pro: Great display,
fast performance, integrated Bluetooth, good battery life by smartphone
standards. Battery is user replaceable, uses non-volatile memory
so data and applications will survive a complete battery drain.
Doubles as an MP3 player and portable video player. Expandable
via SD cards.
Con: No Bluetooth
DUN profile on carrier branded Treos (but one is coming, we're
told), no WiFi and the only way to add it is via Enfora's bulky
sled. On the Sprint version, there's and odd delay of a few seconds
after pressing the send key to dial a number (doesn't happen on
Cingular version). A high end device like the Treo 650 should have
more internal memory. Given that the unit doubles as an MP3 player,
why is a mono rather than stereo earbud headset included in the
