Data stopped after 8 days even I could see the 5G connection
Thank you for your feedback. Upon checking, it appears that a significant amount of data was used during this period. We also didn’t receive any previous queries from you regarding slow speed or connectivity issues.
Feel free to reach out to us if any assistance needed.
I have used esim Japan multiple times and keep coming back beacause of the hassle free experience. The experience has been very easy every time and provided seamless transition to wifi as soon as I landed at the airport. Highly recommend.
It was very easy to use. I’ve had no problem with data. Instant usage of data. Top up was not a problem too
We’re thrilled to hear that your eSIM experience was smooth and hassle-free. It’s great to know that data was instant, usage was effortless, and topping up was simple. We truly appreciate your feedback and look forward to helping you stay connected on all your future travels.
Works good for data but unable to text with iMessage or make calls. Probably better off renting a phone in the future.
Smoth, very good quality of network and competitive prices
