Easy to setup, connection rather unstable
Ordering and setting up the eSim went well.
But connection is unstable. It's either slow or there is no connection at all at times.
The unlimited plan has a fair use policy where it will limit your speed after 30GB, which can be little depending on your use.

Ubigi eSim is Easy to Use
Ubigi eSim is great. I've used them for my last couple of international travels and every time it worked with no problems. Ubigi's eSim is very easy to use and does not require any technical knowledge or support. And the price is pretty reasonable.
The only thing I would suggest is that Ubigi should give returning customers a discount, not just for referring a new client.
