    I'm trying to find the correct variant for the T-Mobile USA bands but am having trouble. I see there's numerous versions and to be honest I don't know which to choose. Does anybody have the unlocked version and can tell me which one it is and how well it works for you? I'd appreciate it!

    This one seems to be the one best as I can tell. RM 1096
    Microsoft Lumia 640 XL Smartphone RM-1096 (Black, Dual SIM) #Lumia_640XL-RM-1096-Black - Expansys USA
    GSM Network: 850 MHz, 900 MHz, 1800 MHz, 1900 MHz
    WCDMA Network: Band 1 (2100 MHz), band 2 (1900 MHz), band 4 (1700/2100 MHz), band 5 (850 MHz), band 8 (900 MHz)
    LTE FDD network: Band 1 (2100 MHz), band 17 (700MHz), Band 2 (1900 MHz), band 20 (800MHz), band 3 (1800 MHz), band 4 (1700/2100 MHz), band 5 (850MHz ), Band 7 (2600 MHz), band 8 (900MHz), band 28 (700 MHz), band 12 (700 MHz)

    T Mobile uses band 4 and 2 for WCDMA and band 4 for LTE. This phone seems to have both.
    Eustis99 and Guytronic like this.

    I appreciate it! I've been trying to figure it out, I hate all the different variants. I've had bad luck in the past thinking I had the correct one.
