Most of well-known Carrier in the US would have a bundled Samsung Galaxy S4. Two of them we already wrote: for Sprint and for AT&T. At this time we would like to discuss about the one for T-Mobile Carrier, the Samsung Galaxy S4 SGH-M919, both the specs and its User Manual.
For the T-Mobile Carrier, the Samsung Galaxy S4 works under GSM data networks technology and also 4G LTE. Under the 3G networks (uses 850/AWS/1900/2100Mhz) the phone can stand by for about 350 hours and 8 hours on internet usage time. It’s almost has the same duration durability for 4G LTE Networks (bands 1/2/4/5/7/17). These can be happened because the Li-ion battery used on the device has 2600mAh capacity. The 5-inches Super AMOLED Display is the most “part” that consume high battery usage.
