Coming from Finland: I have monthly fee of 0,64eur, calling costs 0,064eur per minute, SMS costs 0,064eur per message. For 3G I pay 2,90eur for every starting 24hour of usage without any usage limits, which fits my random travel usage rather perfectly. (For unlimited 3G, it would be about 10eur per month, which I do not need: unnecessary 120 annually versus the current annual ~10eur I'm spending.)
I do not get a bill until I exceed 20eur worth of billing. In my average usage, this happens every two to four months. (As a younger person, using the internet has taken over the majority of my phone usage in the last ten years.)
So yes, paying ~30eur monthly would be rather expensive from my point of view. For that about 30eur / month you can also get a cover-it-all deal here if you use your phone a lot.
With bundled deals you usually end up paying more for the phone in total over time than you would have spent just buying it new. The deals also tie you to the prices of your current subscription for two years, which is bad: you cannot reap the benefits of lowering prices.
Within EU I pay about 0,50eur per minute for calling and about 0,50eur per sms. This is somehow regulated within EU, so of course every company maxes out their roaming prices to the limit. I hope they start lowering the limits sometime soon again. Data roaming is so ridiculously expensive that mostly only corporate users afford to use it on their company phones.
