Is accommodation provided? I been staying here close to 5 months now. I caneed give u some hints sight about the overall expenses:
Accommodation: range about 500 usd to 1.5k depending on your requirement. Best if they can provide you with the accommodation then 2.5k is more than enough to live in East Timor
Internet: most of us using telcomcel $50 unlimited with 6GB, once used up, as usual slightly slow in receiving the data, currentlying they also having promotion for $19
Food wise: eating out will cost you about $ 5 -6 meal around Timor Plaza and decent sized looking shop, if u adore local food, darn cheap, just $1.50 per meal (rice+vege+meat)
As for myself, 90% cooking, I spend about less than USD200 per month. If u are those guys that prefer to eat out, you can do the math by calculating # of meal × $6 × days × times going out for dinner/lunch
Vehicle:if u intend to get a motorbike, cost around 800 (2nd hand) and 1.2k for brand new
