    I recently got a one plus one and I just noticed that when my Voice Call is ON, my mobile Data does not work. I have tried different locations just to make sure there is no coverage issues and accessed the data by disconnecting the voice call.
    My career is Tmobile - USA, and I know my sim card is okay because I was able to use this with the same sim card on my old iphone 5.

    Does Oneplus One does not support voice + data simultaneously.

    I have the same problem, as soon as I make a call, the data disconnects completly. I usually have 3G, H or H+. Switching off LTE helped. I am in France, provider is free.fr.

    Just checked, even when switching it back on, it still works. Maybe a driver issue which gets reset when disabling/enabling LTE?
