Minecraft Realms

I'm trying to get more peeps on my realm. Drop ur mc name in the comments and I'll add you. The realms name is big calcheech

Can't you just invite someone to your regular world whenever they want to join and it will be the same? What makes it worth the price?

So idk about anyone else, but I just redownloaded minecraft on my ps4 since they added realms, but every time I start up the game I don't have anything about realms pop up for me and the game doesn't have to update either. So I go to the minecraft store and search it up, it's there, I go to click on in and it won't pop anything up, I can click on every other little pack and get the ability to purchase them but not realms plus. Am I doing something wrong or what?

I play on pocket edition, I have an account, and I am old enough to join a Realm but how do I join a realm? Do I have to be friends with the person to join the realm or does it just appear?
