In addition to data transmission speed (& increased capacity for traffic), some folks have claimed better call quality on 3G networks. That's probably subject to some debate depending on what network someone is on and where they are using their phone. YMMV.
I'm a MetroPCS subscriber. Based on stuff I've read in CNet & elsewhere, I now know they don't have "3g" network, though they do have a limited "LTE" network which some people equate to "4g". I just happen to be in one of their LTE service areas, but that's not the issue ...
... What I don't understand is this: what is the benefit of 3g or 4g/LTE network? Is is just the data transmission speed?
I am not currently a smartphone user, tho I'm considering buying an android handset. One I looked at has comments pointing out that it is not a "3g or 4g capable" device. What does that mean to me in reality? What features would be impacted or limited by this?
For what it's worth, what I want to use my phone for is primarily phone calls and messaging -- I want to be able to use IM and email on the device, but I don't care about "social media" or streaming anything at all. Web browsing and GPS are bennies, but not a "must have" for me.
