Contacting Curators

I'm from the UK and want to go to university to study the History of Art and potentially go onto do a Masters in curation/museum studies even though I'm really interested in being a curator I want to know find out how to ask actual curators and hear the reality especially the early years of being one and the importance of a PhD.

However I know there are many jobs in GLAM that probably will give better pay and might actually interest me more but I don't know how to research and dig around for them as they might be so niche compared to curators which is probably what people think of when talking about museum jobs.
