In my experience cellular phone networks behave very differently in different countries.

In some places I have made calls where I first hear one kind of ring which is then replaced by a second, different kind of ring. A hypothesis is that one network has played a ring tone while it connects to another network, and that the second network plays the other ring tone as the actual phone is ringing. I have even heard three different kinds of tones when making calls to phones that are roaming in foreign countries.

The global phone network is an incredibly heterogeneous spaghetti of different networks built with different gear installed at different times. The internet looks positively homogenous by comparison.

My point is that you shouldn't rush to positively say "No, you will not hear a ringing."
