I'd love it if someone met me at the airport with a pre-paid SIM card and suggestions for accommodation and public workspaces.
To make that work you would need pre-arranged contracts with a co-working space, some hostels/hotels, phone companies, and transportation services. Using an NFC app to grant access to a coworking space/hotel room would minimize things like key management/inventory. It would be primarily a logistics play but if there are enough people doing this sort of thing it could be profitable.
I could surely come up with a plan where you get mobile internet, access to a coworking space and accommodation if you want to come to Tokushima, Japan to "sightsee" for a month and even meet you at the airport, as I know some people who have a coworking space here. I'm sure others could do that for their own cities.
Not sure what a reasonable fee would be? Would probably take a whole day to organize this for someone, although it sounds fun to meet people.
If I could even go so far as to prepay for a set amount of time (1 to 6 months) for rent, sim, internet, and co-working space and have it all taken care of when I arrive, that would be even better.
As it relates to one specific example on this list, I live in Leipzig, and in East Germany in general, it is nearly impossible to speak English on the phone in order to arrange these sorts of things, plus so many places do not accept Visa (only Maestro/EC card). So coming from the US, you are especially unprepared, and being able to pay OP in USD to have things set up that require German knowledge + lots of euros = huge benefit in not losing money via wire transfer and not needing to know the language in advance.
It would be nice if the current site included a better description of the NomadCost and maybe even an overview of what you mean by the digital nomad lifestyle. It turns out that it is something I have been looking into for a year or so, but I did not realize it was a formal concept.
