Your plan has a different PRL. Thats how your phone knows what to do
with the roaming indicator.

It depends on your service plan. Users of older America's Choice plans
(known as "AC I") get a different PRL than those of the current
America's Choice Plans ("AC II"). And those on the very old SingleRate
plans get different PRLs as well.
Additionally, the PRL is used on EVDO-enabled phones to indicate where
high-speed data service is available. So, those people with
EVDO-enabled phones additionally have a separate set of PRLs that they get.

If you have an old, old, OLD phone, you may not have a PRL at all. You
might just have a home SID input into the phone, and anything beyond
that is "roaming."
But if your phone is more current, it will consult the PRL. I am not
sure if Verizon generates PRLs for those old local plans.

That's correct.
