Phones that made effective use of any significant data connectivity were still rare outside Japan until the introduction of the [[Danger Hiptop]] in 2002, which saw moderate success among U.S. consumers as the [[T-Mobile US|T-Mobile]] Sidekick. Later, in the mid-2000s, business users in the U.S. started to adopt devices based on [[Microsoft|Microsoft's]] [[Windows Mobile]], and then [[BlackBerry]] smartphones from [[Research In Motion]]. American users popularized the term "CrackBerry" in 2006 due to the BlackBerry's addictive nature.<ref>{{cite news|title=Info Addicts Are All Thumbs: Crackberry Is the 2006 Word of the Year|url=http://www.prnewswire.com/news-releases/websters-new-worldr-college-dictionary-info-addicts-are-all-thumbs-55824847.html|access-date=January 24, 2014|newspaper=PR Newswire|date=November 1, 2006}}</ref> In the U.S., the high cost of data plans and relative rarity of devices with Wi-Fi capabilities that could avoid cellular data network usage kept adoption of smartphones mainly to business professionals and "[[early adopters]]".

Outside the U.S. and Japan, [[Nokia]] was seeing success with its smartphones based on [[Symbian]], originally developed by [[Psion (company)|Psion]] for their personal organisers, and it was the most popular smartphone OS in [[Europe]] during the middle to late 2000s. Initially, Nokia's Symbian smartphones were focused on business with the [[Nokia Eseries|Eseries]],<ref>{{cite web|url=http://www.brighthub.com/mobile/symbian-platform/articles/88622.aspx |title=The Nokia E Series Range of Smartphones |publisher=Brighthub.com |date=27 September 2010 |access-date=6 September 2017 }}</ref> similar to Windows Mobile and [[BlackBerry]] devices at the time. From 2002 onwards, Nokia started producing consumer-focused smartphones, popularized by the entertainment-focused [[Nokia Nseries|Nseries]]. Until 2010, Symbian was the world's most widely used smartphone operating system.<ref>{{cite web|last=Schroeder |first=Stan |url=http://mashable.com/2010/02/23/gartner-smartphones/ |title=Smartphones in 2009: Symbian Dominates, iPhone, RIM and Android Rising Fast |publisher=Mashable |date=23 February 2010 |access-date=3 September 2013}}</ref>

The [[touchscreen]] personal digital assistant (PDA){{En dash}}derived nature of adapted operating systems like [[Palm OS]], the "[[Pocket PC]]" versions of what was later [[Windows Mobile]], and the [[UIQ]] interface that was originally designed for pen-based PDAs on [[Symbian OS]] devices resulted in some early smartphones having stylus-based interfaces. These allowed for [[Virtual keyboard|virtual keyboards]] and handwriting input, thus also allowing easy entry of Asian characters.<ref name="JobsKilledTheStylus">{{cite web|last1=Whitwam|first1=Ryan|url=https://www.extremetech.com/computing/98923-how-steve-jobs-killed-the-stylus-and-made-smartphones-usable|title=How Steve Jobs killed the stylus and made smartphones usable |website=ExtremeTech |date=October 7, 2011 |access-date=4 April 2018}}</ref>

By the mid-2000s, the majority of smartphones had a physical [[QWERTY]] keyboard. Most used a "[[Form factor (mobile phones)#Keyboard bars|keyboard bar]]" form factor, like the [[BlackBerry]] line, [[Windows Mobile]] smartphones, [[Palm Treo]]s, and some of the [[Nokia Eseries]]. A few hid their full physical QWERTY keyboard in a [[Form factor (mobile phones)#Slider|sliding form factor]], like the [[Danger Hiptop]] line. Some even had only a [[Telephone keypad|numeric keypad]] using [[T9 (predictive text)|T9 text input]], like the [[Nokia Nseries]] and other models in the [[Nokia Eseries]]. [[Resistive touchscreen]]s with [[Stylus (computing)|stylus]]-based interfaces could still be found on a few smartphones, like the [[Palm Treo]]s, which had dropped their handwriting input after a few early models that were available in versions with [[Graffiti (Palm OS)|Graffiti]] instead of a keyboard.
