It is not THAT bad. The whole nation is NAT'ed. You will not have a proper IP address. almost certainly 10.x.x.x. I use the web a lot, and the vast majority of sites work. Groklaw did not work for me, or BBC. But Tor gets around all of that. BitTorrent is slow due to no inbound connections.
To me the bigger problem is dumbass companies trying to 'help' me by detecting my location and localizing.. Just because I am in Whereveristan does not mean I can read the language. My http headers specify us-en. Do not redirect to chinese, or whatever. Annoying.
Time zones are also a PITA because you are awake and they are asleep, or vice versa.
All that aside, screw the internet, and have fun, eat some new foods, meet some locals, wander around aimlessly. Say "Hello", smile. Many do not speak english, but they all studied it from grade school on up. Write it down. But one of those calculator translator things, and have somebody show you the buttons to put it into english mode. Better ones have sound. About $20-30.
Buy a phone with a SIM card. 110 is like 911 in the states. 114 is tourist help. Free. Everywhere. They speak multiple languages. Tell them what you want, hand the phone to the taxi driver, solved.
