Remo, where are u planning to study? the US or UK or ....
In the UK, you generally need at the least a 3.3 GPA (2.1) plus a high grade at masters to get on a PhD course. Your high GPA at masters equates to a distinction here....but I don't know what your other degree grade is...if it's the equivalent of a 2.2 or third...then your chances of gaining a place (and funding) are probably not as strong.
BUT...so many other factors come into the equation eg. the competition for the PhD course in question, work experience, the standard of your written work, and where you previously studied.
The only thing you can do is apply...and find out!
You should try exploiting the university where you got your excellent masters grades from (they know your best capabilities), and use contacts via your profs at that university as a springboard for applications.
