I tried both Airalo and Nomad when I was visiting Japan , here is my review for Nomad.
The experience was overall very good. Too bad the plan did not offer 5G.

What I liked : 
- Although I had to copy and paste my eSIM information manually the setup instructions were very simple and well explained.
- The plan worked well and offered good speeds. I was able to get 69.2MBS download speed and 18.3MBS upload speed while I did my test in Sapporo downtown.

What I did not like : 
- It's a bit unfortunate I was not able to get 5G while 5G was available in Sapporo
- Since Nomad is not a local network, my internet was roaming through Honk Kong (I guess where Nomad server is). It was not a big issue but added an extra bit of latency.

Really smooth experience! App is simple to use and the internet was fast all over Los Angeles. Good stuff
