Yes, the eSIM is better for data roaming. It is indeed ideal companion on the go: 1.Immediate set up: you can download a carrier’s eSIM profile over the air anytime, anywhere.
2.No more swapping physical SIM cards! An eSIM is a virtual SIM and saves you from having to change your SIM card every time you travel (you could lose it in the process).
3.Convenient: keep your number for calls or texts and use an eSIM data plan for mobile data. You can have multiple eSIM profiles and switch between them depending on the destination you are visiting. So you can decide which plan/ carrier to use based on coverage or data cost. Ideal for regular travelers! Connect anywhere in minutes and keep two (or more) lines at the same time. When you return home, you can immediately resume using your primary SIM card.
4.eSIM is cost-effective. Paying roaming fees with your existing carrier can get really expensive when you’re traveling (have you heard of the bill shock?!). With an eSIM data plan, you benefit from rates close to local on mobile data. Want to save up to 90% roaming charges when traveling abroad? Download the official Ubigi app and always stay connected to the Internet in 200+ destinations.

Super easy to get an e-SIM and get it connected. I didn’t have anything to worry about while I was in Canada for data. I would totally recommend getting one of these e-SIMs. I would totally use them again.

Nice options for data
Nice options for data, and good prices. However, it was confusing to activate the eSIM. The email support gave more information, but ultimately it was the QR code that was needed to activate. I had to figure this out on my own.

Service at the top of Mt. Fuji!
From the moment we landed to the end of our trip we had great service! We mostly stayed in Tokyo, and we did a small stint in Kawaguchi because we were planning to climb Mt. Fuji. My fiancé has an android and I have an iPhone, and we both used Ubigi! The only time service was spotty was on the bus leading up to Mt. Fuji's 5th station. Once we got to the 5th station we had good service all the way to the top of Mt. Fuji! I was honestly so blown away by that!
Last trip, we used pocket Wifi and lost service at the top of Mt. Misen which is a much much shorter climb. Plus, it was nice not to have to carry anything extra this time around.
Would highly recommend!!

Works well yet still cheap
Cheap, straightforward, pretty fast, and works well! I especially appreciate the regional ip service, making the internet faster than other similar esim providers.

Easy to install and use
Easy to install and use. Installed the app and started the service when I was in Japan without issues.
Have shorter terms and lower data plans will keep Ubigi even more competitive.

Super easy
Super easy. As soon as I got off the plane I was prompted that my wifi was active. I never had to do anything else and never worried about it. I was able to easily navigate trains and activities with no worries.
