Lumia 850 in Japan

swinefeaster

    Hello,

     

    My wife switched to tmo to take advantage of the free data roaming in Japan, and was also told her phone is compatible. She is now in Japan but the data roaming doesn't appear to be working.

     

    What should she see in her system tray to indicate she is connected correctly to free roaming? Which carrier and which band? Currently its says LTE and something like "4000"

     

    Thanks
