Oh, yes! Let's not
start another "what's a tier one" war!
Oh no, let's :-).
We get over here in Africa as well. Local operators either calling
themselves Tier 1, or being called a Tier 1. Nonsensical.
Years back, our Marketing team asked me to comment on the use of
"Tier" for our literature. You can probably imagine what I said :-).
For me, it's simple - you are present in X cities or Y cities. Tier
is useless because the Internet does not come from a single country
or a single operator. And saying a network is "big" or "small" is
subjective to everyone's perspective, so that doesn't help either.
So you're present here, and present there. That's it.
