Perfect Esim for Japan trip
Was quite easy to use. Reliable connection most of the time
The overall service has no issues. However, I ordered from Australia, and according to the information provided, "Upon confirmation, the SIM card can be mailed or collected from the AIRSIM office." The AIRSIM office proactively contacted me to inform me that mail service is only available for Singapore, Hong Kong, Taiwan, and Canada. I managed to bring the SIM card back to Australia, but it would have been a frustrating experience if I hadn’t received it before my trip, as I would have needed to rearrange for a new SIM card.
