Fast and reliable

Fast, reliable and pretty easy to use. I’ve never used an eSIM before and bought a Ubigi sim for my trip to Japan after doing some research online. I didn’t quite understand out to activate it but managed to work it out quickly enough. It always had service, especially in the quieter villages we went to and despite using it for Google Maps for 1300km of road driving, I barely cracked half of my allotment. Would use it again for sure!

Super convenient an reliable!

I used Ubigi eSIM during my trip and absolutely loved it! It was very quick to set up and super easy to use — I had instant connection right after activation. The internet speed was great, and I never had any issues throughout my travel. Highly recommend it for anyone who wants a hassle-free data experience!

Accessible WiFi

Ubigi has provided me with accessible internet access whilst in Japan which compares very favourably to my previous experience of renting routers and accessing free WiFi in cafes and such like.

We bought the country package for Japan. It uploaded as soon as we arrived here & we are enjoying the unlimited package. Working really well & easy to use.

Worked well but took a little sorting out in settings

It wasn’t quite as simple as download and it will work when you get there. I had to go into settings to select the “travel” sim for mobile data. The sim itself worked perfectly all over Japan.

Very convenient

Got it for Japan and is very convenient. It automatically connects upon arrival, and the app will let you know how many data you have left.

Simple and easy to purchase and use

Simple and easy to purchase the best option based on our trip. Then setup was nice and quick, with good reminders when I was in the area purchased for use. Would definitely use again and also recommend to others.

I used the ubugi e sim for 12 days while travelling to Japan. I found it very easy to install and very efficient. I will certainly recommend and use it again.

Good service.

So Simple that a 60 Year Old Can Use It

At 60 years old, I had doubt and anxiety finding a way to stay connected to the internet on my cellphone while visiting Germany from the United States. My son told me about Ubigi. While at the airport, I signed up and downloaded the Ubigi App. The directions were simple and clear especially providing images of my cellphone setup features. Once I landed in Germany, the activation was automatic and seamless. When I have WiFi, I can use it and while I don't have WiFi, Ubigi automatically takes over. There are many packages and prices to select from. I love that there isn't anything I physically have to buy and install. So simple that a 60 year old can use it:)

Very happy so far.

I am still in Tokyo. My Ubigi e-sim is working well. It uses Docomo. The 5G is fast.
