If I upgrade from 15 to 60Mbps when does the change start?

Hi Manon

All plans modifications will be effective your next billing cycle

This is the text from the guide

Important – any change to your plan must be made 48 hours before the end of your payment cycle. During those 48 hours, systems are frozen and no change can be made. You’ll therefore have to wait for the next payment cycle.


On the first day of your payment cycle, when your new plan will be valid, make sure to restart your Wi-Fi modem:

1. Unplug the power cable on your Wi-Fi modem.
2. Make sure all the lights on the modem are off once you have unplugged it.
3. Wait ten (10) seconds.
4. Plug your modem back into the electrical outlet. Expect a three (3) minute delay to allow your devices to reconnect to the Wi-Fi network.
