Re: coverage Actually they have good coverage on 2G and 3G just about everywhere and if you look at the maps showing coverage and towers on OpenSignalMaps they seem to actually have better coverage in most places than any of the other companies. The problem though is they don't have hardly any coverage with 4G and very few 4G towers. 3G and 4G speeds are about the same though and either one would probably do just as well for most people. They have been selling 4G phones lately that don't get 3G so there's no coverage. It doesn't make sense to me at all. Why would you sell service with a phone that doesn't work? I think they are their own worst enemy. The lack of 4G towers must be why they had one of the Samsung phone updates change the display so it always says "4G" now no matter if you are getting 3G, 3.5G or 4G. On a phone like the Galaxy S that gets both 3G and 4G they make it look like you are always getting 4G service even though it isn't very fast in a lot of places. |

kudos:2 | How can that be? 3G is UMTS(WCDMA) on AT&T and T-Mobile. HSPA+ is an upgrade of the UMTS spec, sort of a software addon, like EDGE is vs GPRS for GSM, correct me if I'm wrong. All the former AT&T 3G towers show up as 4G hspa+ on my lte capable smartphone, but work just fine on my backup 3G phone with about the same signal and call quality. The hspa+/lte phone just gets much higher data speeds. I thought hspa+ phones were backward compatible with plain umts, like the hspa+ towers with my plain old umts phone. I know both phones(4G and 3G, along with all my prior 3G phones) can(and have) fall back to EDGE(GSM). Does T-Mobile not have the hardware to do that built into their phones?

| Selenia, it depends on the phone. My Samsung Exhibit 4G can't get 3G but the Galaxy S can. Here they use HSPA+ on 1700 Mhz for 3G but WCDMA for 4G. The reason 3G towers show up as 4G is because one of the firmware updates made everything say 4G now. My Galaxy S used to say 3G when it was on 3G and 4G when it was on 4G with Android ver. 2.2.1 but after I updated it to the latest 2.3.6 it says 4G all the time now. |

HUH?
"3g" and "4g" are the same damn thing.
WCDMA, UMTS, and HSPA(+) are all the same. HSPA+ is a higher capacity data bolt on to UMTS. WCDMA is the radio interface for UMTS. It's all the same, dude.
"3g" is typically just up to 7.2mbps HSDPA. T-Mobile refers to "4g" as 21mbps HSPA+ or higher.
No idea what you're referring to with your particular phone. You may want to go talk to T-Mobile if you're not getting 3g/4g service when you're covered by it.
