Very easy to set up, instantaneous.
Tried their Smart Traveller eSIM and it worked great! It connects to Digi in Malaysia, and XL in Indonesia. Both 4G. It roams via Thailand but decent speed, no trouble at all. Tethering worked too. No fancy app or anything but it just works.
It worked really well for my trip to Jakarta. You just need to change APN and turn on data roaming, then it connects to XL or Indosat 4G in Indonesia. Speed is good and stable, ping is acceptable (it roams through Singapore). Overall good experience. Recommended.
