My first contact with the Internet was about 20 years ago. I was a Universal student. The University had 64kbps bandwidth, it was really slow.
Nowerday, I have 128kbps mobile network with 950 yen/month. It is usable for some use case, like text messaging.
Update 2013/12/14Nowaday, the mobile internet service is improved, so I can use 30+Mbps LTE connection with 500MB/month limitation, and if I reached the limitation, I can access with 200Kbps speed limitation.
