Yes, the building is usually in red color - the Telkomsel color, so you can't miss it. Unfortunately I don't have any experience buying the 4G SIM card there, but I'm sure they can help you.

Wow, poor with capital. I know Indonesia is not the best when it comes to internet connection (and other things), but it doesn't give you the right to call it a poor country.

It happens also to domestic tourists. I usually say "tidak, terima kasih" (no, thank you) and ignore them.

Sorry about it. It's typical Indonesian (or other developing countries). I myself got ripped off in Bromo when I traveled with my European friends (and I am Indonesian!). I've never done the route from CL to Yogyakarta, but I would say the ticket should cost around 150k. Ask for a PATAS bus. PATAS is not the brand. It just means faster bus and equipped with AC. They normally have a fixed price. This link is outdated, but should give you an overview.

I was once in Prague. In my opinion, Czech Rep is not that cheap. You could try looking for B&B. A good one is like a hotel room, minus some hotel facilities.

Okay, thank you. I hope the new passport will be finished by then.

So, if my second flight is from the same terminal, I may be able to go through since I will not have to pass the immigration control? I just noticed that there's this requirement with minimum passport validity and I have already booked everything (trains and flights), thinking it would be no problem since I'm going home anyway and wanted to renew my passport there sigh

I booked it as separate tickets; Emirates and AirAsia.

I will be traveling with two different airlines. The first airline flies to Kuala Lumpur (they require 6 months validity). Do you think it would be okay? I will stay 3 hours then continue fly to Indonesia. I am currently in the process of renewing my passport, but I'm not sure if it will be finished on time. I would like to avoid changing the whole itinerary.
