My wife will be in Buenos Aires for 2 months and staying in a place that has no wifi. What is the best solution that will allow her to watch netflix/youtube and do a bit of browsing on her laptop? Buy a local sim, put in her phone and use as a hotspot for the laptop to connect to? just worried that will just gobble up a lot of the data very quickly. any suggestions would be appreciated as she is breaking my balls over this.
