We bought 2esims for our 2 1/2 weeks trip to Malaysia. Esims worked perfectly from the minute we landed. Great customer service when we almost ran out of data and was given free complimentary top up.
We will not hesitate to use AirSims again for our future travels.

Absolutely amazing

Absolutely amazing. Had no issues with service anywhere. Needed some help activating my sim and the help was immediate. Will definitely use again when going abroad next time.

Initially cautious but good experience

Activation was simple. I installed before the trip in Australia and while it will try and activate it won’t be able to until you land in Japan - just wait a while and it will stop attempting and you can turn it off until you land (see the end of the FAQs). My phone had trouble trying to activate while we were still on the plane but activated fine in the terminal (why yes, I am impatient.. what gave it away?).

The SIM worked fine in all areas of Japan we travelled to - from the middle of a busy city to more rural areas in Central Japan. My partner had an eSIM from a different provider utilising a different network, and anywhere that my SIM did not work theirs did not have much reception either so it was an equivalent experience. The network provider is IIJ, who utilises NTT Docomo as mentioned in the product description. Unsure that I ever got 5G however, I was mostly on LTE as far as I can recall.

The only issue that I had with this SIM is that it didn’t allow tethering/mobile hotspot in my experience. If you are wanting to share your data with someone else (your partner, your child, someone else) or even just tether to your tablet or laptop while out and about you won’t be able to do that. If you do not need this capability then you’ll find this SIM works perfectly.

Worked well!

ESim worked well. Connected as soon as we got off the ship and had coverage the entire time we were in NZ from Dunedin to the Bay Islands.

Works fine downunder

I travel a lot and been using Airsims for data eSIMs and it’s been pretty good. This is my 2nd review. Quick to set up, worked instantly, and I’ve had no issues with speed and coverage everywhere I’ve gone (so far no issues). No weird apps that ask for too much information and control of your phone (I work in cybersec) or annoying setup process, just straight-up data that works. Prices are reasonable and fair, not expensive like some others. Also tried cheaper (and nasty) alternatives and gave me grief. Seems they got the mix of cutting out the nonsense and giving a decent product. It’s simple, does what it says. If it were a clothing brand I’d say it’s like Uniqlo or Toyota car (I was in Japan not too long ago). Also used on my kids iPads without drama.

Great travel eSim, good speed and coverage

Travelling to Japan, I bought the eSim a few days before I landed in Japan, works greats with good coverage and speed, excellent price compared to other. I end up buying a second eSim for my partner. Highly recommend it.
