Thank you. I often get people responding that 2G speed will work fine for email, chat, Google Maps etc. Maybe if I installed an IMAP client on their phone, maybe.

But I can promise you from sitting with them dozens of times things like Google Maps are unusable once the connection is throttled. It might load some of the map, some of the time. But it never loads all of it and it is just plain unworkable. Even if it loads some of it it takes so long that the busses have gone past by the time they've tried to figure out what direction they need to go.
