    Revert "us: change Visual Voicemail number for T-Mobile USA"
    
    Revert https://gitlab.gnome.org/GNOME/mobile-broadband-provider-info/-/merge_requests/30,
    because the voicemail is 123, but the visual voicemail number is 127.
    
    See-also: https://gitlab.gnome.org/GNOME/mobile-broadband-provider-info/-/merge_requests/31
    
    This reverts commit 12da7cd6a65b898cbf6922d0714551910e0016b1.
