Open a document with an existing link, then tap the linked text or the link button on the linked object.
If the link is in a table cell, tap the table cell first, then tap the link button.
In the link editor, tap Link Settings.
Make your changes or tap Remove.
When you remove a link, the link text is retained but the link formatting is removed and the link is no longer active.
When you’re done, tap the document to close the controls.
Pages automatically detects valid web addresses (URLs) and email addresses, and styles them (for example, with an underline or different colour) to indicate that they’re active links. Phone numbers aren’t formatted as links by default, but you can turn on automatic formatting for phone numbers. You can also turn off automatic link formatting for URLs and email addresses.
To change whether or not Pages formats website URLs, email addresses and phone numbers as active links, you can update the settings for automatic formatting.
