I'm not sure what you mean here... wouldn't your 2 GB cap directly affect whether or not you can browse? I do agree that a normal user might not hit that limit. I do Gmail, some streaming, and some tethering, and I'm only up to about 1GB.
What I meant was that they seemed to be suggesting that the type of data you use is restricted. For example, that you can't browse the web AT ALL. I was just trying to point out that I think the restriction is how much data you use, not how you use it. So of course you could use up 2GB by browsing, streaming, tethering, whatever. I was just saying that you CAN browse and do normal data functions...up to the limit, which is the real restriction.
Ordering my SIM today. I am on wifi whenever I am home anyway, so I really am not worried about going over 2GB. Even with my current/old TMO plan, I rarely go over 1MB with regular use. I am not what some would call a 'power' user I guess. I keep data on 24/7, and use it regularly, but for routine things like mentioned before, email, etc. I am not downloading full hd movies or anything. The most data intense thing I do on a regular basis is browse the web to find something and then map it out/get directions with Maps, and maybe retrieve email attachments.
