Used 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.

★★★★★ 2/5

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!!

★★★★★ 5/5
