Frequently asked questions

Gohub eSIM is one of the strongest options for Japan if you want prepaid mobile data, fast QR-code setup, and no need for a physical SIM. Depending on the plan and local availability, service can connect through major Japanese carrier networks for reliable 4G/5G coverage in cities, tourist areas, and main travel routes
Yes — Gohub eSIM works in Japan on supported plans. After purchase, install the eSIM before departure, then turn it on when you arrive. Your phone should connect automatically to a supported local network once coverage is available
Install your Gohub eSIM over Wi-Fi before departure, then switch it on when you arrive in Japan. Once your phone detects a supported local network, the plan should connect automatically, so you can start using data without visiting a store or swapping SIM cards.
In many cases, yes — a Gohub Japan eSIM can cost less than using your home carrier’s international roaming pass. For example, Verizon TravelPass and AT&T International Day Pass are both listed at $12 per day for many destinations, so a prepaid eSIM can be a more cost-effective option for short trips or data-focused travel. Final savings depend on your carrier, trip length, and usage.
For most travelers, 5–7 GB is enough for a casual week in Japan. If you stream video, upload lots of content, or work remotely, 15–20 GB is more comfortable. As a simple rule, around 1 GB per day is a safe estimate for active sightseeing with maps, messaging, bookings, and social apps. Gohub offers multiple Japan plan sizes so you can match data to your itinerary.
Yes — you usually need Wi-Fi to download and install the eSIM profile. It is best to set it up before departure. Once installed, your Japan eSIM can connect to a supported local network after arrival without needing Wi-Fi.
Yes — if your phone supports dual SIM, you can keep your home SIM active for calls or texts while using your Gohub eSIM for mobile data in Japan. Exact behavior depends on your device model, carrier settings, and whether your home line supports roaming or Wi-Fi calling.
Gohub eSIM for Japan works with many unlocked, eSIM-compatible smartphones, including iPhone XS / XR and later, Google Pixel 3 and later, and selected Samsung Galaxy models. Compatibility can vary by model, region, and carrier lock, so it is best to check your device against Gohub’s compatibility page before purchase.
Many Gohub Japan eSIM plans support mobile hotspot, so you can share your connection with a laptop, tablet, or second phone. Because hotspot availability can vary by plan, it is best to check the product details before purchase.
Usually, yes — Gohub eSIM should work well across Tokyo and along major Shinkansen routes when connected to a strong local network. Coverage is generally strong in major cities, stations, and travel corridors, although signal quality can still vary in tunnels, deep underground areas, and some remote sections.

Was around Chatuchak at night, probably too crowded so the signal got weak for a bit. It was already late but I messaged the Gohub team and still got a quick response. They helped fix it right away. Love this team 🔥

First time traveling solo, a coworker recommended Gohub for eSIM. Was a bit skeptical at first. Once I arrived, it worked right away, nothing to worry about. I asked quite a lot since it was my first time, but the team was very helpful. Will buy again next trip 👍

Used it for a few days during the holiday trip. Everything was fine. Didn't run into any issues so I didn't even need to contact support.

Anyone who travels to Japan a lot probably knows KDDI is very reliable - strong signal, low lag. The price is usually a bit high, but Gohub had a deal for this network so I grabbed it for the whole family. The entire trip was smooth, messaging and calling back to Vietnam worked well. Overall, pretty solid.

Business trip to the US. Biggest concern was unstable internet during work. My boss recommended trying Gohub eSIM. Throughout the trip, nothing came up that I had to deal with. I'd say it worked well.
