Experiences like this illustrate why we should all have T-mobile if possible - if your eSIM has problems, you have your free T-mobile roaming as backup, which almost always works.

I've used these before and had no problems. You've always needed to register on their app before using the SIM, but the process seems to have changed - previously you needed to physically be in Singapore before you could start that process, but this time I had no issues doing it whilst on the bus to the airport in Melbourne, and it even successfully connected to the network there.
However it simple refuses to connect to the network in Thailand. Google shows that this seems to be a common complaint, and plenty of people have suggestions on how to fix it (APNs, manually selecting networks, etc) but none of them have worked for me. Contacted support via chat, but apparently their only option for this package is to call me back "within 1-3 days"...
My 'backup' eSIM of Firsty Free also isn't working. It at least connects to the network, but only 3G and then refuses to bring up a data connection on it. Purchased a 1 day/500MB package from Global Yo (for 59 cents), and thankfully that one is working fine.
