Given a travel related situation, and given a specific question about the situation, summarize the question into a title

Input: Consider Input: If you look at GoSim's rates (or the rates of other international sim cards), you can see that it has both a US and a global number. What is a global number? Is it the number you dial internationally to call the US number? Then why are the fees higher for receiving a call?

If it is a separate prefix for these numbers, why can't I find any information about these numbers in Wikipedia's list of country codes?


Output: What is a global number?


Input: Consider Input: The official UK document says: 


  You can bring in other goods worth up to £390 (or up to £270 if you arrive by private plane or boat).
  
  If a single item's worth more than your allowance you pay any duty or tax on its full value, not just the value above the allowance.


The question: 

Is the tax-free allowance applicable per an individual item or per total cost of all items combined in a baggage?

If you need a more detailed example, here it is. 

I am relocating to the UK and going to take my desktop computer with me. I want to disassemble it and put small parts into my backpack and big parts into a suitcase that will be put into aeroplane's luggage. All these parts will be with me upon my arrival to the UK.

As for the computer. I bought all its components separately in my country and put them all together and used the computer for around a year. Almost all the parts in the desktop were cheaper than the tax-free allowance except the Video Card.

What will I be charged for? For the sum of all the components prices or only for the video card? 


Output: Is the tax-free allowance applicable per item or per total cost of all items combined in a baggage


Input: Consider Input: I am going to the Netherlands and might need to get a train. (Between Eindhoven and Amsterdam). On www.ns.nl (the large train operator that does that route), they list the price as €17.90ish. That's for booking it online.

However, I'm not sure what price it'd be if I were to turn up on the day and buy a ticket for the next train going that way.

Here in Ireland if you book train tickets online in advance, it's much cheaper than if you arrive in the train station and want to buy a ticket for the next train. (e.g. €20 online vs. €60 last minute in some cases). Is this the same in the Netherlands with NS or is it the same price regardless of when you book?

Update I don't care what sort of train to take, I just want to get from Eindhoven to Amsterdam.

Money isn't too much of an issue, I just don't want to be asked to pay €50 per ticket when I could have got it for <€20 had I only booked online!



Output: Is it cheaper to book Dutch train tickets online in advance compared to paying on the day?
