Write a reviewMuch 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 doesnโt respond to any help after 24 hours.
Paid and activated the sim but couldnโt get any internet connection (despite successfully connected to SoftBank 3G).
Iโve 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, canโt use map, checked settings, trouble shooting, everything is fine, three people bought, nobodyโs eSIM works
