Finland has tuition free PhD programs for nationals of any country, Germany and Netherlands offer paid research positions where you basically are a full time student and still a part time lecturer - working hours can be tough though, since you need to balance the two. If you have some modest savings, Malaysia has some excellent universities and very cheap tuition (I’m doing my phd here and pay about 10k USD for a 3 year program) and cost of living is very low.
