Should you buy your Ubigi eSIM data plan before traveling, or when you arrive?
Either is possible! You can purchase your Ubigi data plan right before you leave or when you arrive at your destination, whichever is most convenient for you. Thanks to the SmartStart feature, the validity period of your data plan starts automatically upon arrival in a covered area, ensuring you do not lose any days before your travel.
Getting started with SmartStart is easy! 🚀 Upon arrival, simply switch on your Ubigi line in your mobile settings—your data plan will activate automatically, and its validity will begin.
If you have not purchased a plan before leaving, you can buy your data plan when you arrive at your destination and it will activate immediately. Good to know: Even after you have used up all your data allowance or you have no Wi-Fi, you can still recharge from the UBIGI app anywhere in the world and check data usage.
Note: We recommend installing your Ubigi eSIM on your device before you travel. Internet connectivity is required to download the eSIM profile on your device. (For Android users, you can only install new eSIM profiles while connected to Wi-Fi).

Overall good but there was a 10-14 hour period where the service was down. Thankfully I could find wifi to supplement, but it would have been bad if I wasn’t able to.

A good ESIM
I had to change eSim providers whilst in Japan as the one I was using was very troublesome. Many Ubigi reviews were positive, so I downloaded it. Found it easy to set up and it worked very well. There was one small outage, but Ubigi have corrected it and offered compensation, great integrity.

Perfect Experience
I used an Ubigi eSim for my two weeks in Japan. It was my first time using an eSim and the process was very simple. The app explained it well and I had no issue with activation.
I purchased an eSim with unlimited data for peace of mind. I used it frequently and daily, mainly for social media, communicating with family and navigating Japan. I had no issues with connectivity in Tokyo and Osaka. I would absolutely recommend Ubigi and will definitely use it again later this year for my next travels!

It’s a must-have when travelling abroad. The eSIM was easy to install and came with clear instructions on how to change the mobile settings upon arrival.
I experienced some downtime for a few hours, but the follow-up service was excellent.
I would recommend Ubigi to all travellers!

The eSIM was great
The eSIM was great. Worked As soon as I landed. It did take a bit of time following instructions to load the eSIM as QR code did not automatically work from email.
Would definitely use again,

Works pretty good
Working pretty well had just few times that it had some issues. But altogether so far have been quite smooth sailing with this internet service. Funny that it works so well when we stayed in Okinawa but the connection issues what I have experienced have been in Tokyo. Just short issue not anything major. So altogether great service.
