I've been using the free unlimited roaming from T-Mobile on several trips to Japan, Argentina, France, and Italy. Often, the speeds are actually faster than EDGE, unless the network is busy. I have had no issues using Google/Apple Maps or booking hotels, etc. through this connection. The only thing I miss is having Hotspot capabilities, even at the reduced speeds.

EDGE is consistently, unbearably slow for me. If the phone has negotatiated EDGE, you should be getting EDGE speeds, which has a maximum bandwidth of 236 Kbit/s (theoretically up to 473.6 Kbit/s according to Wikipedia). That's not fast. I occasionally get reduced to EDGE on the Berlin subway, and I barely get Hacker News up.

(LTE has a maxmimum of about 450 Mbit/s, but in practice it's closer to 15-50 Mbit/s down, maybe half that up.)

Maybe someone who knows mobile technology could chime in.

In my experience, it's usually LTE but speed capped.
