Good 2 know
There’s also a Telkomsel (mobile phone company) booth before the last duty-free shop at the airport, selling local sim cards. Prices are higher than on the street, but they will explain everything very well and wait until your new SIM card works. It’s also possible to only book a data package, so that you can use the internet, what’s app and navigation (plus: very good if you want to go for Uber). Because of the traffic during peak hours it can take quite long to reach your Hotel/Homestay. But don’t worry, you already paid a fixed price at the counter and don’t have to tip the driver later.
Happy planning! 🙂
