The phone was unlocked when bought it so I first checked the IMEI on the 'Protect your data.ca' site. Then I checked it out on the Telus site and it said it was not compatible.
Thanks for the URL on the Telus site. I bought a used BlackBerry Z10 and needed to check the IMEI number for compatibility. I now find it is not compatible with Telus but it is for the Bell network. I don't understand why that would be.
