Aftaer that, bitcoin could help as fiat as well.
That is what those people need who lives in the poor countries. And that is not going to be an easy thing to make those poor countries being helped by bitcoin. For they first need the facilities, computer, laptops, smartphones or any gadgets that allows them to be connected in the internet. And that is the way when bitcoin do its job for helping them.
People from poor countries will not prioritized in getting that things since they care for their money. Since the source of money is difficult no way they will put their money in that kind of thing. The price for that is not a joke plus the internet fees which I doubt will be present in those rural areas.
Without internet bitcoin can't help those poor people.
Very true, they would not intend to engage up onto these things because they would surely prioritize first their needs rather than investing into bitcoin or engaging on it. As you mentioned not all people do have internet connection and thats already an expenses and they would not like to add up on it.
