T-Mobile 1900MHZ HSPA(+)

     For a while now T-Mobile has running their new 1900 MHZ network to target AT&T users because all new devices have the 1900 MHZ PCS band so T-Mobile can give HSPA service to devices without the 1700/2100 MHZ bands.

   T-Mobile has been covering Washington DC with 1900 MHZ since the day it was launched and yes did I get excellent speeds with the compromise of coverage, meaning that due to lack of coverage 1900 MHZ can reach my speeds were lowered to EDGE in buildings and received numerous dropped calls. But, let's look at the history behind 1900 MHZ, the band was originally used by AT&T (still is today) to provide GSM/UMTS to their customers so this band is the reason why AT&T earned it's reputation back then as having the spottiest coverage in the US. So to keep it's customers AT&T did a 850 MHZ refarm, similar to what T-Mobile is doing but T-Mobile is doing this at a slower rate due to not having the money to deploy spectrum in every market. But if you would still like to try out T-Mobile's 1900 MHZ network you can do so for less than 40 dollars and use this as an on demand service or use it for primary uses.
 
  If you would still like to test out T-Mobile's new 1900 MHZ network I'd recommend using a device like the Nexus 4 or a device with 1700/2100 MHZ bands as T-Mobile non 1900 MHZ network is AWS so you need both 1700/2100 MHZ bands to get T-Mobile HSPA when not covered by 1900 MHZ. But if you live in an LTE market, I'm pretty sure the super fast LTE speeds will compensate for the lack of 1900 MHZ coverage.

Sprint Sucks

        With Verizon wireless being the only carrier in DC having full 3G service (EVDO) underground really makes me wonder as testing all carriers Cricket was last and found a tie with AT&T and T-Mobile and Sprint was third but the thing is Cricket is a prepaid network so they are kind of an exception.
        
         Now with Wmata telling us that there will be service at all rail stations by 2012 and they told us that in 2002 which devestated me as Sprint does not have service even at some of the busiest stations and T-Mobile offered service but it was not consistent. However AT&T has had service at either every 2 stations or every station but here is why they both tie sometimes when using AT&T I was unable to make phone calls but with T-Mobile it was great service just wish it were consistent. Sprint had service in areas where lots of tourist are like Smithsonian station but data speeds were absolutely ridiculous litterally they were fast for EVDO A. With either carrier they won't disappoint even Sprint as they are upgrading their 3G network which is always nice.
