“Nice”
“The price is a bit high but the network worked perfectly and the speeds were good. Also the app they have works very well.”
“Much better than I expected for a travel eSIM. The Japan eSIM I bought from Airalo wasn't the cheapest, but latency was surprisingly good (below 40ms) even though the IP address was from USA, which probably means they are doing a local breakout. The speeds were good, more than sufficient for travel needs, and the coverage was also satisfactory.
It would have been the perfect option if the price were cheaper.”
“Great experience. Got the eSIM in a sale. Activated while still at home, immediately got connection after deactivation of air plane mode. Speed was good, coverage OK. One downside: location was sometimes detected as Singapore, which was not always great (Microsoft send me a lot of warnings because it was routed through SingTel Mobile in Singapore). ”
“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.”
Airalo for Japan FAQ
Does Airalo offer unlimited data eSIM for Japan?
Airalo does not offer a truly unlimited high‑speed data plan for Japan; the “Unlimited” plans listed give a maximum of 3 GB per day and, once that limit is reached, reduce the speed to 1000 kbps. For travelers who want a consistent high‑speed experience, Airalo provides fixed‑data plans such as the Asialink 100 GB plan valid for 180 days or the Moshi Moshi 20 GB plan valid for up to 30 days. These plans do not throttle speed after the data cap is used and can be more cost‑effective for heavy‑data users.
Does Airalo offer Japan eSIM with phone number and SMS?
Airalo does not provide a Japan eSIM plan that includes a local phone number with voice call or SMS capabilities. All Japan eSIM offerings from Airalo are data‐only, enabling internet connectivity.
Travelers who need voice and messaging can still use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, which works without a traditional phone number or SMS service.
How many data plans does Airalo offer for Japan?
Airalo offers 17 single‑country eSIM plans and 40 multi‑country plans that include Japan. These plans cover a price range from roughly $4 to $89, data caps from 1 GB to 100 GB, and validity periods spanning 3 days to 365 days. Plans are grouped into fixed‑data and daily‑cap types: fixed‑data plans provide a set amount of data for the entire validity period, while daily‑cap plans reset each day, which can be advantageous for short stays.
