Hi.. I think it is depend on what you want to do. I am applying for ph.d for next year as I realised that I need a full career as I am working for the government. In many countries, governments agencies hire more and more ph.d grad. And as you are just master degree holding, to get promote for higher position is tougher. Well, I don't know what job you are looking for. I don't know to go for academic career, but i want a bigger step in my job. Good luck for job searching
