The story
Amp'd Mobile (2007)
Telus Mobility's competitor, Bell Mobility, had an MVNO partnership with Virgin Group to create Virgin Mobile Canada. This brand was in operation since 2005, and it mainly targeted high school, college, and university students. In response, Telus Mobility had a similar but much shorter partnership with the American Amp'd Mobile in 2007 to create a Canadian MVNO. It was ended because the Amp'd Mobile operations in the United States suffered from poor customer service and bankruptcy. This meant that unlike Bell, Telus no longer had a mobile brand targeting students.
Koodo Mobile launches (2008-2009)
Nearly a year after the launch day of Amp'd Mobile in Canada, Telus launched Koodo Mobile on March 17, 2008, in Canada. This mobile brand provided services at a lower cost than most other companies.
BlackBerry and transition to HSPA+ (2010)
Many customers at Koodo requested the addition of full QWERTY keyboard devices to facilitate text input for SMS and Internet-based tasks such as email and social networking services. On May 25, 2010, Koodo launched their first smartphone, the BlackBerry Curve 8530. The following month, Koodo released the Nokia 3710 as their first HSPA+ device on June 28, 2010. After this date, the company gradually started to discontinue sales of CDMA devices.
HSPA+ smartphones and Canada-wide monthly plans (2011)
Six HSPA+ smartphones were released in 2011. The first was the LG Optimus One, launched on March 2. Later that month, the BlackBerry Curve 9300 was available starting March 23. The Nexus S was added to Koodo's lineup on April 12, 2011. In order to prepare for the back-to-school season, Koodo discontinued sales of all CDMA devices near the end of June 2011, less than a year after the carrier launched their first HSPA device. Shortly thereafter, they were replaced by the iPhone 4 and two low-cost Android devices.
