Can I make phone calls with Ubigi eSIM data plans?
Ubigi eSIM provides data-only services. Thanks to Ubigi data plans, you will be able to connect to the Internet wherever you are in the world.
So, you can not make phone calls with Ubigi eSIM data plans but you can use iMessage and your favorite VoIP applications such as Skype, FaceTime, WhatsApp, Viber, Facebook Messenger, etc. By using these VoIP apps, you will be able to make calls and send text messages.
For iPhone users, you can also keep using your home-based carrier line to make calls and send SMS while using Ubigi mobile data. Calls and SMS will be charged by your domestic carrier.

Slight issue in the start, otherwise stellar service.
Had zero issues other than the startup, perfect connection for two weeks, even on top of a mountain.
Make sure you pre-install the eSIM in your origin, critically DISABLE your local SIM before boarding, and in Haneda (Japan) there's no point to try and connect to it while still in the plane due to local infrastructure, wait until you're in the terminal to connect.

Ubigi is great for travels abroad
Ubigi is great for travels abroad. I had some difficulties when setting it up, but figured it out at the end. This the explanation could be a bit clearer.

Our eSIM works just fine
Our eSIM works just fine. Only issue we had was it did not start sutomaticslly. We had to go into the cellular setting on our phone and make the eSIM the primary. It would have been nice if it had been named Ubigi rather the cryptic Travel-transatel. But once setup it works well.
