There have been multiple times where I get to the point in the conversation with the producer and ask about Internet. Without internet I can’t send out call sheets on time, merge pdf documents, look up maps or locations etc. Its especially important when I work as a 2nd AD. One site I use to rent WIFI for a temporary period of time is https://www.wifirents.com/ This site is great because they mail you the wifi gear and then you mail it back when you are done. No year long commitment etc..
