Seamless transaction for my Apple…
Seamless transaction for my Apple device. For Android, however, I failed to receive a QR after my transaction and had to email support a couple of times with redundant back and forth of the same information I have already given on my first email. Ended up arriving on my destination country without that data I paid for for a day. CS does reply fast, but the redundant email still makes this a bad experience. Hopefully it won't be like this next time.

Good service, could be better
Used the eSIM during my trip to Japan and Singapore. In Japan, everything was smooth since I moved only to Tokyo city. In Singapore, I often had a very weak internet signal (LTE). For the rest, UBIGI is a great provider.
