Nivused MTX Connect MTX Connect in Japan 🇯🇵

The internet was extremely slow on almost all websites except YouTube. I got the 50€ unlimited package. I don't recommend at all

Nicoused MTX Connect MTX Connect in Japan 🇯🇵

I purchased the "Unlimited" 30-day plan, It turned out to be misleading. Once I exceeded 1GB of data usage in a day, the speed throttled down to 250-500Kbps.
There isn't any clear mention of this limit.

The latency remains relatively low since the internet breakout is located in Singapore.

~1GB per day at full speed for 50EUR is very expensive, I wouldn't recommend this plan.

The purchase/installation was straightforward.

Perfect, reliable and flawless experience in all countries with good 4G speeds (15-25mbps)!
I used the „pay as you go“ plan!
Easy to choose and switch via the app.
Refill/prepay is also done via the app! The only minor catch, minimum refill amount is 10€ and it‘s 10€ steps from here (10,20,30...)
Overall really good experience!!

Frequently Asked Questions

Does MTX Connect offer unlimited data eSIM for Japan?

MTX Connect provides an unlimited data eSIM plan for travelers in Japan. The plan, called JAPAN SPECIAL OFFER, runs for 30 days and is priced at $58.01 USD. While it has no data cap, the provider notes that speeds may be throttled and a fair‑usage policy may apply, potentially reducing speed after heavy use. Travelers who need confirmation of the fair‑usage limits and typical data amounts at normal speed are encouraged to contact MTX Connect directly.

Does MTX Connect offer Japan eSIM with phone number and SMS?

MTX Connect does not provide an eSIM with a local phone number or SMS capability in Japan. Only data‑only eSIM plans are available, so travelers can use the Internet data and rely on VoIP services such as WhatsApp, Telegram, or iMessage for calls and messaging.

How many data plans does MTX Connect offer for Japan?

MTX Connect offers one single‑country plan for Japan and four multi‑country plans that include Japan. The single‑country plan provides a fixed data allowance starting at 350 MB and can be purchased for periods of 1 to 30 days, with prices ranging from about $4.05 to $58.01. The multi‑country plans, which cover Japan along with other destinations, similarly vary in data caps from 350 MB to unlimited and in price across the same $4.05–$58.01 range; some plans may throttle speed depending on usage. These ranges give travelers a broad choice of data options when selecting MTX Connect for their Japan trip.
