The Airhub eSIM in Malaysia was fairly reliable and worked well most of the time, though there were occasional moments when the signal dropped and had to be refreshed by toggling airplane mode on and off. Unfortunately, I couldn’t find a way to check the remaining data balance, which made me a bit anxious about running out of quota when not connected to Wi-Fi. Strangely, access to ChatGPT didn’t work either. Overall, decent for basic use, but with a few limitations.
