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.

Had near perfect 5G connection everywhere (except the last day at Osaka airport, took a while to connect but got it back just before Taxiing). Best part was my phone didn’t heat up and drain my battery trying to find/connect to the network like some other eSIMs i’ve used before. Will definitely stick to ubigi for future Japan trips

Second time around
Used during Japan/China holiday in 2025. No issues at all, so confident to use in Europe Amsterdam & Budapest. Good value rather than high data roaming charges from Aus Telcos

Tokyo Japan Trip 2026
We took our Vacation to Japan this year and assumed our phones would work there but no bueno. Meet a fellow American in the lobby who let us know about Ubigi. What a game changer! There are multiple plans which I find excellent for how long your stay will be. Not money gouging app where it’s just this or that. I will recommend Ubigi to all that will be traveling. Love the App. Simple and very fair $. Than you for making our trip ez
