They built their own mobile core, does that help with resolving your "Big If"? I'm not a cellular guy, I don't know which pieces of the stack cover which attack vectors: I'm genuinely asking.

Also, the 50 foreign countries seems interesting.

Do they own the enodeBs or the RAN? How many hops does it take to get to their core? Not sure how MVNO works maybe they have encrypted VLANs to their systems. Not a RAN guy.

		We don't own eNodeBs/gNodeBs (the RAN). We operate as an MVNO. It is worth calling out that we operate as a full MVNO though, which is different from many MVNOs in the US currently, who tend to fall on the lighter end of the MVNO spectrum. The primary difference is we run our own mobile core entirely. Can you elaborate on the hops question? Not sure I quite understand what you're asking since there are a few ways to interpret "hops".
