It goes without saying that the Queen is no ordinary person, so you can't just pick up the phone to be able to speak to her - not even some of her closest family.
There are strict rules in place for anyone who wishes to contact the Queen, as it could create a huge security threat if anyone were able to reach the monarch.
Luckily technology has moved on a lot over the last few years, which means Her Majesty is now able to have a personal mobile phone which is protected against hackers - but she only uses it to contact two people.
