Why we like it
Ubigi is one of our favorite eSIM providers, and in our 4.5-star review we found that plans were fairly priced compared to the competition. We found it very simple to setup the eSIM on our phone - it took a couple of minutes to load the eSIM on to our device before travelling. Once you land, set. It's impressively straightforward.
Top features for us include the 4G and 5G connections on KDDI and NTT Docomo networks, support for mobile hotspot and tethering, and the option to top-up your data even once you've run out.
Ubigi's eSIM is also reusable in over 200 destinations, making it a good choice for frequent global flyers. The platform works on a wide range of phones, laptops, and tablets, which we really like. For the full list, check out the broad device compatibility list here.

Value verdict
We've praised Ubigi in the past for offering excellent value for money - even at full price, the data plans are cheaper than most providers. This reader-exclusive deal, shaving 15% off the price with TECHRADARJP15 only adds to the value. If you only need unlimited data while traveling to Japan, this is an easy recommendation.
