Just to be clear, Sprint is not an MVNO. They are a Tier 1 internet service provider.
Boost, Virgin Mobile, Ting and a handful of others would be MVNOs using Sprint's network.
MVNOs, by definition, do not have/provide their own network.
I think there was a misunderstanding.
I was just explaining that I'm using sprint but through an MVNO
And for the record I have used sprint directly and through an MVNO and the service is been essentially identical and great both ways (for me anyways).
