My wife and I are to the USA (California, Nevada and Utah) for 3 weeks in an RV at Christmas. My wife can take her work phone for calls home but we have to really limit the amount of data that we use on that phone.
We will mostly be using data for google maps so a couple of gigs would be plenty for the three weeks or so.
Does anyone have any experience with getting a sim in the USA for data?
Advice?
