Customer reviews
Chen Lineused iRoamly
The internet worked perfectly everywhere – airports , even on road trips. No annoying "loading..." screens! Plus their customer chat is LEGIT. Messaged them at 1AM (jetlag lol) and replied in 2 minutes. She literally stayed on chat while I set it up, double-checked everything. Way cheaper than my phone plan back home. Never going back to regular SIM cards!
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.
