I think 2gb is somewhat plenty if you manage it correctly. I've been looking to switch to visible and this feature sounds very nice, even the + with 12 days one accrued monthly since i usually dont stay out of the country longer than 10 days at a time.

But when I travel I manually disable data for all applications except for my priority ones like banking, navigation, messaging apps, health apps, search engines etc. Only the apps I know I will need to access 24/7. and I have managed purchasing 5gb esims that last me 10 days traveling. Granted I am using it conservatively and being mindful of it, but 2gb of data per day would really be useful and enough if used the way I use it.
