NorthSIM - South East Asia Travel eSIM
Essential a scam. The eSim I bought from Yoho Mobile appears to install bout there is no data. The network is forever in Emergency mode and there is zero data. Absolutely nothing. I was basically scammed out of $18 I paid for this Sim.
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.
