Using another provider is the easy way, but doesn't really solve the problem, in fact.
Even though it seems like a precarious solution, I'm looking forward to hear the result of your try.
Moreover, the problem itself can be solved at its root either by making the case for compatibility with Poste itself, as Jacopo was suggesting (which might as well work),
Jacopotediosi Io una (più di una) mail a Poste con in copia il CTO l'ho mandata, e vi invito a fare lo stesso.
or through higher, EU-level regulation tackling the gradual closing down of the Android environment. That would solve many other things...
