EDIT: I have edited the question severely so that it better conforms to the format of a more successful CW question: What problems and solutions arise with data access when travelling through multiple countries?
When I travel, I find that there are certain things I always have to do, regardless of where I'm going.
Some examples include notifying my credit/debit card issuers of my travel plans, learning specific phrases in the local language, writing down key pieces of information in my notebook, etc.
When I talk to other travelers, I find that many of these same things apply when they travel as well — regardless of where they are traveling, they run through these same "preflight" preparations as well.
In an effort to come up with the bare-minimum list that is as widely-applicable as possible, I posted What tasks would I need to complete to prepare for any international trip, regardless of destination?... which was closed almost immediately (and fairly, let's be honest) as being too broad.
I think this would be an excellent community wiki question — it's something that would make a great reference for travelers across the board, and quite frankly it's hard to find a list like this on the internet (the closest that I've found is on wikihow.com, but even this is mostly tips rather than checklist items).
How can I improve the question to make it relevant/answerable for this community?
Also, if you agree that this would make a valuable addition to the Travel.SE community, would you visit the question and submit a reopen vote, please? (:
