I have a Nokia Lumia 520. However when I want to use my Lumia 520 I have to remove the battery to insert the simcard. When I boot my Lumia up I notice that the time & date are not correct even when it's connected via wifi or 3G.
Is this a bug with WP as I had a Lumia 710 too and it does exactly the same thing.
