Great service
I have used Ubigi a couple of times and recommend it to people. Normally it's been all good. My last trip I made a mistake and bought the wrong type of plan (I bought 'Germany' instead of 'Europe') which meant I had to either buy another plan or go without Internet. In future you shouldn't have the option to make that mistake. With jetlag etc, it should be easier to get a plan that covers Europe (which you have), without making the mistake.
