Earlier today I talked to azure sales rep. about bandwidth pricing he told me that inbound and outbound is free as long it’s in within same region. Since I want to create a cloud platform (like dropbox, onedrive etc.) does that mean my bandwidth is free as long the traffic is within Europe? If that is true which countries are considered to be within that region? If not what did he mean by that. I’m planning to deploy in Eu West region.
Also he said that when I asked about this particular text. "Data Transfer In: Free". You can find it here.

Please read the conditions and documentation on Microsoft’s site – nothing anybody on StackOverflow says matters, their conditions are what matters and that’s what you’ll be held to, no matter what anyone on the internet said.
Having said that: "within the same region" means "not leaving Azure, and not leaving the same region within it" – downloading from Azure to anywhere that’s not Azure (even to a service running on AWS or Google for example), or sending data to another region even within Azure, will set you back the cost of the bandwidth.
This means that, for example, if you have a database in one region, and an app that reads it in another region, and then writes it back to the first, you pay for bandwidth twice, since your data left twice. If that app then has a front-end you use from a browser, you pay for that bandwidth as well.
Note that the documentation is pretty clear on this: "Bandwidth refers to data moving in and out of Azure data centres, as well as data moving between Azure data centres; other transfers are explicitly covered by the Content Delivery Network, ExpressRoute pricing or Peering." And the tables underneath show the rates – they just use the somewhat obscure term "egress" to talk about ‘data leaving’.
