Say hello to seamless travelling in Japan, with Ubigi eSIM as your trusty sidekick.
Let us catch you up to speed with the latest travel trend: physical SIM cards are out and eSIMs are all the rage. While there’s a plethora of options in the market, the travel eSIM from Ubigi caught our eye with shiny promises of 5G data in over 60 destinations, easy set-ups and affordability. And when better to test it out than on vacation? We sent our Senior Lifestyle Writer, Sufyan, on a mission to try it during his week-long trip to Tokyo, Japan. Spoiler alert: his connection was as reliable as Japan’s subway system!

Starting off strong with a foolproof set-up
The first test? The eSIM activation. Thanks to a simple and direct set-up process, Sufyan was off to a great start.
He shares: “I was still working up to the evening before my flight, so you can imagine me stress-packing and making sure everything is in order. For the installation, I just scanned the QR code using my phone’s camera and the eSIM was added within minutes. Easy, breezy, beautiful!”
For Type-A travellers who are all about colour-coded spreadsheets and detailed itineraries, you’ll be pleased to know that the eSIM from Ubigi can be purchased up to six months in advance. Plus, you only need to install it once and can easily top up your data plan for use in over 200 destinations. Perfect for staying on top of your travel preparation! And not to worry, your plan will only start when you reach your destination.

Upon landing at Narita Airport, Sufyan’s first order of business was to check his connection. “The Ubigi eSIM was immediately activated and rarin’ to go. This isn’t hyperbole, I assure you,” he shares. This is all thanks to Ubigi eSIM’s SmartStart feature that automatically activates at your destination upon the first network detection.
Stable through tunnels and deep underground
But the true measure of a reliable eSIM connection isn’t at the airport or in the city centre. It is put to the test when you’re deep underground or navigating Japan’s more rural areas.
Sufyan was impressed by the stability of the Ubigi eSIM: “After activation, I never experienced any drops or slowdowns. Through tunnels, underground, and even venturing outside of Tokyo, I still had mobile data.”
Even during an unexpected work emergency where he had to schedule a heavy upload (a video post, no less), it was done in a jiffy without losing connection.

Armed with a 50GB data plan, Sufyan also tethered data to his travel companions when they didn’t have enough. The unrestricted tethering feature has his stamp of approval: “No drops or slowdowns for my connection, and my friends navigated perfectly thanks to my data!”
Pro tip: download the Ubigi mobile app to track your data usage and do data top-ups on the go, even without any remaining data or Wi-Fi connection. Round-the-clock customer support and a multilingual chatbot are also available for troubleshooting anytime. Browse the full range of Ubigi’s eSIM data plans here!
Goodbye, unreliable Wi-Fi and poor connection
After a week of sushi, ramen, serene nature, and boutique shopping, the Ubigi eSIM never once let Sufyan down.
“Overall, I have no complaints. Easy set-up process, no data drops or slowdowns… What’s not to like? Ubigi is beginner-friendly, and I reckon even older folks can use it without running the risk of giving up ‘cos it’s ‘too technical’. It’ll definitely be another eSIM I’ll look into for comparison when I’m travelling overseas and searching for affordable yet fast options.”
