MTX Connect eSIM Data Plans for Japan

“I noticed that the pay-as-you-go option does not appear in the plan listings on esimdb, which caught my attention a little. After actually using it, I personally feel this is the most convenient option.

Because it is fully usage based, you can keep using it seamlessly even when moving between countries, which is incredibly convenient. With cheaper flight tickets, long layovers at airports in China are common, and sometimes you may want to head into the city for a short while. In those situations, it feels a bit wasteful to purchase a one day plan or a large data package, so this option fits perfectly.

Airport WiFi is available, of course, but connections can be unstable, and SMS verification is sometimes required, which often makes it more troublesome than expected. That is why having the reassurance of being able to connect immediately on your own mobile line, even during immigration, feels very valuable.

Overseas roaming is also available with ahamo and Rakuten Mobile, but there are still countries that are not covered. Having this set up as a dual SIM feels like something that could really help in an emergency. I also appreciate that LINE and WhatsApp continue to work even after the main data allowance has been used up. It is a small detail, but genuinely useful.”

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

“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!!”
