Could not find the person nor the shop that would supply the SIM Card. Received a WhatsApp message to meet someone near the lift in the arrival hall?? So this means outside the building where the taxi drivers wait... either way a truly poor experience and service. I would recommend for anyone else, once you pass immigration just shop at the shops inside the terminal and buy 15gb for 100,000 IDR or 10 AUD. Would never use again, terrible service.
