Very slow even with excellent signal strength (4G, iPhone XS), unusable even for maps and messaging. Very high ping times (600ms+). Support is very slow as well and did not fix the issue nor provide a refund.
Extremely poor support that doesn’t respond to any help after 24 hours.
Paid and activated the sim but couldn’t get any internet connection (despite successfully connected to SoftBank 3G).
I’ve checked many times that apn and roaming is enabled. And re started my phone multiple times.
Issue was never resolved and Airalo support was non existent.
Showing not active all the time, can’t use map, checked settings, trouble shooting, everything is fine, three people bought, nobody’s eSIM works
Horrible speed across the entirety of Japan, feels lile youre locked in 2G/Edge. Tried multiple reboots, changed speed profile, tried different networks, it all is of an incredible poor quality. Not worth your money. Switched to another leading eSim provider, night and day! I now can finally browse.
This is my second time using Airalo in Japan. It works okay but it seems the carrier switching doesn't work perfectly. When that happens I just have to turn on -> off flight mode which is a bit annoying but not too big of a deal.
It connected to au (KDDI) 4G most of the time, occasionally docomo (NTT).
The speed is decent but it's roaming via Singapore so there is a certain latency for sure.
The screenshot attached is the one I did at Narita airport.
