Re: Not that deep
I've had the opposite experience. At work we switched from O2 to EE, and now the only way I can make or take a call on the mobile at home or work is if I stand next to a window. I thought maybe it was my fault for flashing AOKP onto my S5, but my IT Manager's M8 has exactly the same issue after switching to EE. He even said that it was due to EE's signal penetration being awful.
At home the wife's Note 3 is on Vodafone and gets a great signal, while mine says 2-3 bars, but still can't make/take calls.
