I have to echo this comment. I recently travelled to Japan and Singapore, and I managed really well on the 3G speeds I got from T-mobile's free roaming. I'll admit I didn't spend my time there streaming youtube videos, but I did use instagram and occasionally google maps, although it was slow for maps sometimes (then again, maps is slow here in the US too, it's most likely my SG SIII not playing well with the latest and greatest maps version), moreover, I tethered from time to time. At the end, I paid a pittance (something like $2) because I had to make one call. For me, T-mobile's free roaming was a godsend.

I usually cache google maps offline when traveling to another country: https://support.google.com/gmm/answer/3273567?hl=en
