Customer reviews
Françoisused iRoamly
I used their unlimited 3-day plan and could use more than 20GB of data, so it seems to be indeed unlimited. However, the speed was capped at 10 Mbps the whole time.
Traffic was routed through Hong Kong, so the latency was not great but not too bad.
The issue with a Hong Kong IP is that I couldn't access some services like ChatGPT.
