I read there is free wifi hotspots at the departure or arrival hall of the airport? Have to make use of it so I can do a booking or else I would have no way to book it.
UPDATE: Oh yeah, I just need to buy a pre-paid visitor SIM Card. Will get that then book an Uber.

Gonna try
this one from dtac.
UPDATE2: Just ordered the tourist SIM online and will pick it up when I land.
