Moving to dublin

Hey guys, I'm 24 years old girl and I'm gonna move to dublin probably around april or march from indonesia. Is there any tips for newcomer here like phone plan service, what to expect, what not to do, stuff like that? Also do you think making 28k euro per year is enough? It might not be much I know :( but I'm excited to be starting. I would love to meet and make new friends there since I know no one so please anyone who wanna help a sister out that would be great. Thank you :)
