Hamei speaks truth in his usual hyperbolic way (or so I hope)...
As a northern European, the US prices seem absolutely insane. The norm here used to be a per minute charge for phonecalls and per-message SMS costs (back when we have marks it was 1mk per message as I recall) in a subscription fashion, you signed the contract, got to choose your phone number and was given a (full size) SIM card. Thanks, goodbye. Also we sell phones here if... oh, you have one already, fine.
Data, as it were then, was a per-minute charge as well but as GPRS and EDGE moved to 3G it turned into rate-limited tiers, where you paid a certain amount for a certain level of service. Splendid. I can't remember what I paid before but the subscription I had up til last year with a 512k (up/down) speed limit (easily enough for my needs) was about 10 euros a month.
Some time after the introduction of EDGE the mobile operators started to get wind of this data cap business from abroad (I presume), and started selling packages with "1000 free minutes" and "1000 free messages" thing "for the heavy consumer", nothing that I was really interested in because I send and receive on average a quarter of a message a month and about as many phone minutes.
This has now morphed into a full data cap, all plans I found while looking for an LTE upgrade it seems come with "minutes", "messages" and "gigabytes" and cost a fair lot more... I was fortunate that my old provider allows upgrades of only the data service but I couldn't chose a rate limited one (but with the added latency benefits of LTE) so now I'm paying about 27 euros a month with (theoretically) more bandwidth to my phone than my home connection... (50Mb/s vs. 10Mb/s fibre) *grumble* PAYG please...
Prepaid is available, you can get a SIM card in any store or kiosk, as well as refills but it's socially seen as something for foreigners and losers
In any event, it boggles my mind that US subscribers blithely pay so much for phone service and can only hope that the service providers here get a grip and go back to the good old ways.
Also, is it true that you can be charged for receiving calls or messages in the US?
