The website is very clear that the phone SIM-only plans are called No Frill, Essentials, Essentials Plus, All Rounder and Full Works. It describes what each of these plans includes.
However on the upgrade screen it lists some plans which don't specify what type they are. They almost look like data-only plans but surely it wouldn't offer those for a phone SIM upgrade? Can anyone identify these? Are they somehow Essentials plans but with some sort of free EU roaming added? Nowhere in the checkout process does it specify what these plans include.
