[Leica] OT: Sim Chip in Europe

[Mark Rabiner]

T-Mobile works great in the Bronx and Brooklyn but in Manhattan on the Upper west side where I live it works if you are standing in the middle of a Broadway and there are no trees or real tall buildings anywhere near you. Verizon does work here in an elevator or basement so I can lay on my bed and talk. What a luxury! But if I moved to the Bronx I'd have to move to T-Mobile again.

    They vary widely. See
         
    https://cellphonesignalbooster.us/blog/lte-frequencies-and-bands-of-cell-phone-carriers-in-usa-canada/
    
    T-Mobile uses 1900 MHz Band 2 LTE, 700 MHz Band 12 LTE, 1700/2100 MHz 
    Band 4 LTE.
    
    And see https://www.frequencycheck.com/countries/germany for example. 
    Germany uses Band 3 (1800+), Band 7 (2600) and Band 20 (800 DD). I see 
    no overlap with T-Mobile US frequencies, but sometimes phones have 
    hardware for bands not used by the carrier.
