The most important thing that you will need to activate the YouTube app is a valid Google account. It would be better if we first told you how you can create the account and then go into the activation process. But for this info and to learn more about the YouTube channel activation, you must first visit our website @ youtube.com/activate. Our website is backed by an excellent tech support team who can be reached out at our toll-free number on +1-844-730-3890. We also have a live chat line if you need quick remedies to any pressing issue with the channel.
