It's not the search string that needs escaping, but rather the regex. It'll work if you apply the escaping you tried to search's first argument instead of note:
note = "Call +201099973073.Midnight"
print(re.search(r"\+201099973073", note))
Output:
<re.Match object; span=(5, 18), match='+201099973073'>
