There are so many prepaid cars services, eventually it will depend what kind of communication and where you call.
I personnaly am a reseller for a VoIP company that is compatible with any kind of mobile prepaid or postpaid service. It is great to call international and sometimes also national.
when you use a prepaid mobile : I suggest you Proximus, you can use the gateway of nomado to call to national or international.
In exemple, you will be able to call around 13ct/minute to Italy with Proximus and nomado (need to make an online activation at www.nomado.eu)
