Egress/outbound bandwidth internet data transfer (free per month)

Question

Hello I would like to ask for explanation of egress bandwidth data transfer to internet, because I already found three different values through your pages:/

Here: https://azure.microsoft.com/en-us/free/free-account-faq/
we have:
Transfer data inbound and outbound through our robust network of global data centers. 15 GB outbound 12 months
Transfer data inbound and outbound through our robust network of global data centers. 5 GB outbound Always
I don't understand logic with 5 & 15 at one place, or you can have 5, or 15, or maybe this will be the sum = 20??

Here: https://azure.microsoft.com/en-us/pricing/details/bandwidth/#faq
you have: Internet Egress
First 100GB / Month

Here: https://azure.microsoft.com/en-us/pricing/free-services/
you have again: Bandwidth (Data transfer)
15 GB outbound

So basically I have question how much exactly egress data I will have after I will finish my 30days trial (which probably has also 15gb as per my account info) & I will upgrade to pay-as-you-go & I will use this with 1 free tier B1s instance
-5
-15
-100
or maybe some variation
-20, 105, 115, 120

When exactly this 100gb apply, with what kind of subscription, server etc?

Thank you for the clarification :)

Hello, @Pedro K !

These are good questions. Let me try to clear up some of the confusion on the first question although I should note that pricing information is subject to change and you should always check with Azure Billing for any pricing related questions.

What is the free monthly amount of bandwidth (data transfer) for a free Azure subscription?
The amount of free data inbound and outbound through our network of global data centers for a free Azure subscription is currently listed as 15 GB outbound for 12 months and 5 GB always (check the free Azure subscription FAQ for current offer details).

This means that for the first 12 months, the first 15 GB outbound is free each month. After that (always), the first 5 GB outbound is free each month.

What is the difference between inter region and internet egress?
The Microsoft global network (inter region) offers optimal performance and integrity compared to the public Internet (internet egress), giving you more reliability, faster speeds, and less latency. For example, the round trip time between East US and UK South is only 74 milliseconds.

The free first 100GB currently on the Azure bandwidth pricing page refers to internet egress. If you wanted to move or duplicate files within Azure (deploying your app to multiple continents for example), you would benefit greatly from using the Microsoft global network where the first 5GB are usually free (as noted in the answer above).

You can see this in the Azure Pricing Calculator where it's a bit clearer once you play around with the numbers:
