This is a member-to-member Discussion Board, no one from ebay will see your post to help you fix your phone number.
But here is how you do it.
1. Find your Account settings. This can be accessed from several different points but this is the one I like to use at the top left of the page. It is best if you do all this on a desktop as opposed to a mobile device.
2. Go to Addresses. Phone numbers are stored there.
3. When you get to Addresses, chose your Primary (assuming you have an alternative, skip that one and use Primary) and when you open it it will look like this but with your information autofilled.
4. Change your phone number to one that suits.
Be sure to come back if you need more help, or for some reason this doesn't work. And don't post personal information like a phone number in a public forum like this; not everyone who sees it will be friendly like me. For your own safety, I've asked the Discussion Board moderators to obscure your contact information.
