    I recently unlocked my Lumia 820 and put an Austrian 3 (Drei) SIM card in it. The connection in the top left corner shows that it has connection and then after 1-2 seconds it says no sevice for one second and then it's good again. Why ist this happening? Tried it on WP8.1 WM10 10166 and 10512. I have a feeling this drains my battery really fast. The fast battery drain is only on WM10.
    Tested the battery, without SIM it drains normal.

    FIX: I have got only a 3G connection and my phone was set to 4G. I set it to 3G and it Works now! Yay.
