I bought a galaxy note 5 recently. And since I got it, it has been having an on and off connection with the rogers network both voice and data at the same time. Someone in the community mentioned about loose sim card. So I did a follow up on this angle. I taped the sim card to render it immobile. I never had a disconnection since then. If you sandwich the adaptor with the sim card in it, in between two microscope glass slides, and shake it, it's noticeable the card moves.
