*TELUS and Bell HAVE NEITHER ANNOUNCED NOR INTEND TO BUILD ANY
GSM network.
*Their upcoming
HSPA networks will be deployed in the existing Cellular (850MHz) and PCS (1900MHz) spectrum, just like what the existing CDMA2000/
EVDO Rev. 0/A networks are deployed in.
*A
GSM-only phone (e.g. Quadband
GSM 850/900/1800/1900) WON'T WORK on the upcoming TELUS or Bell
HSPA networks.
*A
3G capable phone w/ only
WCDMA/UMTS/
HSPA 2100 WON'T WORK on the upcoming TELUS or Bell
HSPA networks.
*A Multi-mode/band phone that INCLUDES the
3G WCDMA/UMTS/
HSPA 850/1900 (e.g. Quadband
GSM +
3G w/ 850/1900) WILL BE REQUIRED.
*RIM
BlackBerry Storm 9530 offered by BELL, for example, DOESN'T support
3G WCDMA/UMTS/
HSPA 850/1900, just 2100 ONLY!
Right now the only phone that Bell has that would work on telus and rogers is the
BlackBerry Tour which you need to have it unlocked.
i dont know the specs on the Sony Ericsson K800i but assuming it follows the rules above you could quit rogers and use it with bell or telus
