Yeah that wouldn't be too bad. I saw about .1 Mbps in Amsterdam and Italy on the T-Mobile SIM and also about that at MUC.

But at MUC it seemed even less responsive compared to the other locales.

I have an upcoming trip, a week split between Vienna and Prague. They both have decent prepaid options but would cost about 20 Euro each. Too much to spend for one week for faster speeds, unless the hotel Wifi is really bad.

Will see if T-Mobile is good enough for 2-3 days. My $10 a month data only Simple Choice plan may increase in price at the end of this year so I have to see how useful it is.
