I had 2 days stopover in Singapore and decided to get a local e-SIM so I had data when walking around (useful for maps, ordering cars, calling restaurants etc). Was working when I arrived and had plenty of coverage everywhere I went. My only issue at one point my phone said I was now roaming (I had turned off my Australian SIM) but I saw that the phone thought it was connected to a Hong Kong provider. I turned on data roaming and everything worked again. No idea why it decided I was in Hong Kong when I was in Singapore but didn't matter in the end. Great service I'll use again.
