"You can transfer any existing phone number to your TELUS Mobility account, including numbers from other carriers and landline numbers. You can request a number transfer after you have received your device and have set up your My TELUS account. If you’re moving a Koodo or Public Mobile number to TELUS, please request a number transfer after receiving your device and SIM card. Your existing phone number will replace your temporary TELUS number once the transfer is complete".
