So, I arrived in Kuala Lumpur on Monday and the SIM and Data was working, so maybe they fixed it remotely (or something).
When I arrived, I had data credit of $100USD and 1 day later, it was gone, all of it. The hotel, bars and restaurants I visited all had WiFi so lord only knows where the credit went? I used data for Uber but that’s about all.
When I arrived in Manila, I bought a SIM for around £0.40 and bought call & data for around £4.00 and the store topped it up for free, to last 3 days with 1GB free data.
I will do the same in Cambodia.
I think WorldSim was a good idea originally, but in reality, it doesn’t perform in a way that I find useful or easy to track.
