There are plenty brother... now don't know which place you are going to...and i think not really in a mood to write all the things at the moment. anyway let me give it a try,
1. mobile connections here aren't for free and one must get the connection at the earliest even to commute here as it helps you in navigation such as bus routes, time of bus arrival, which bus number to catch from where to catch etc. wind/fido are good to go... however, if you are bringing your phone here, wind has got a different frequency it works on... i mean the signalling stuff... so you can check that online...better google it...
2. if you are from Asia, then better don't bother much about your winter wear as it will not be good enough... winters are bone chilling here...though don't worry as long as you are in the house, hotel, room, bus, you won't feel it.
3. bring few items for sure no matter where you gonna live, hostel, hotel, shared room or wahtever... bed sheets, cushion covers,... rest don't worry about things much as you can have all from near by stores... like dollar shop and factory seconds....
4. whichever place you gonna land in, try to check your accommodation in advance... so once you are here, you can simply visit 3 to 4 shortlisted options and finanlize...
i guess can't write any further... call me if you need any further help... you can reach me on + 1 6 4 7 7 0 1 8 6 6 0
