Pro/Con in Wales
Pro: cost, ease of installation, app shows usage info, instruction on turning cellular on/off for primary & ubigi esim is clear (didn’t get international roaming charge by primary network:).
Con:some spotty network in Wales (thought I would get EE, but didn’t).

Good service
Good service to solve my issue resetting my eSim on my new phone.
Excellent connexion quality tested in France, Korea and Japan. They offer the best of local providers at a reasonable price. Personnally I don't care for huge amount of Gb that others sell if they cannot provide a good connection... I think that Ubigi is the most sensible choice

We.bought the Ubigi application and charged it 10 Gga for a 12 days trip in Japan.
After 3 days it seems to work super fine, easilly and surprisingly we did not used a lot of G of our package !! ( NB : in hotels there is also wifi to be honnest...). Probably it would be good if unsused purchased data could be saved and used for some other future trip...)
Great application and system.

No issues with Ubigi in Japan or the UK. Easy. I just topped up as needed. Did 3 gig for $9AUD first in UK. And with family wifi it was enough! In Japan I used 3gig first, topped up got 10g next. I used google translate a lot in Japan. Ubigi is 5g network. Linked into wifi wherever possible but it’s not everywhere. You need a eSIM.

Great Data Connection in Japan, but Issues Receiving Calls & Texts
I used Ubigi’s eSIM during my trip to Japan and overall had a great experience. I had no issues with the data connection and was able to use my phone normally while traveling—maps, social media, messaging, and browsing all worked without any problems.
The only issue I experienced was with receiving regular phone calls and text messages. I wasn’t able to receive them properly while using the eSIM. I’m not sure if that was related to my regular phone carrier or the Ubigi eSIM itself, so I don’t want to blame Ubigi for something I can’t confirm.
For data use while traveling in Japan, though, Ubigi worked really well for me and made staying connected very easy. I would definitely consider using it again on a future trip.

It just worked.
Honestly, it just worked. I don't believe it ever dropped connection when I didn't want it to drop (i.e. turning off mobile data to make absolutely sure I was using wifi). Speeds were also more than satisfactory for the duration of my trip.
