Apart from the question what the idea is behind posting plans with no prices for phone or plan, is their data really that bad. The most you may per day if you use more data is 9 SEK per day or 270 SEK per month ($45). It will of course be less as you are unlikely to use all your allowed bandwidth the first day and you may not use enough to reach the max every day. So if the plan is low enough, it seems like this could still end up with a reasonable cost. It is however funny that they don't have an unlimited plan when they clearly have limited what you'd pay if you used data without a plan.
