Last week I upgraded my phone and plan and hubby got my old phone with a new sim card and phone number on my same account as cheaper that way. We did the reset and wipe all data etc from my old phone and set his up. The issue is that I have noticed when I text a friend and she responds (this isn't happening with all numbers), hubby gets all our correspondence. Same when someone calls his number it also rings mine! How can we fix this as though there are no issues with privacy for us, it's just damned annoying!!!
