I am currently in north Italy at Lago dIseo close to Verona. I bought 3GB Monty eSIM for 5days. With almost full LTE reception I am experiencing single digit KB speeds, internet is only reasonably usable for text. At these speeds it is obviously impossible to use the data volume I paid for. Technically higher speeds are proven to be possible but I seem to be throttled after the first 100MB.

I can only recommend to avoid Monty eSIM.

I decided to take a chance and sign up on-site since it was cheap. Less than 1,000 yen for 5G. To my relief, it connected just fine.

The initial 1G I purchased worked smoothly, making me think I'd made the right choice. However, when I bought an additional 10G as it was about to run out, I couldn't use it at all. I was grateful that they responded quickly when I reached out, but in the end I was unable to establish a connection and had to get a refund.

The customer service was commendable and it's a shame that I could not continue to have the good connection I experienced initially.

It was almost unusable.
I bought 5G but I had trouble connecting, perhaps due to incorrect APN settings. Sometimes it miraculously connected after trial and error, but in the end I couldn't even use 500M.
When I tried to contact them, they were slow to reply, and in the end, when I returned home, they replied simply 'not sure'.
