IMHO you want something impossible.
In the matematical language, you would like introduce the linear order in the set of international prepaids . I mean: for each two prepaids A,B there's a relation A<=B (A is worse or the same as B). And it's difficult to compare values of any two prepaids even for a specific person, nothing to say about comparison for any possible user.
