It worked well for my son's trip in China. He forgot to turn on roaming, and thought it didn't work. I contacted them and the response was very quick on a weekend. Great service!

easy to use

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.

Good value. Connected automatically when we landed in France. No problems when we travelled through Europe. Will use again.

Super easy set up, worked with Facebook, Google etc., very reliable and a great price.

Works perfectly as soon as we landed at Kuala Lumpur airport.

I purchased the sim for a short trip to Bali! It worked perfectly and was great value! Will use again on next trip!

Really came handy in a pinch! Very easy to install, had no issues - will be using again!

Recently used this e-sim on a trip to Canada and the US. Worked well overall, easy to set up and get started!

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.

Easy to set up, and got connected right after landing. Highly recommended 👍

Ive travelled to Malaysia and Taiwan with Airsims. Very easy connection and good coverage.

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.

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.
