I use my normal phone
.
All contacts, email and web browsing are done within secure folder( previously knox).
You can't copy and paste from within this to your normal party of your phone.
The only thing you have to remember is to delete texts and call history, this needs the normal part of your phone to do this.
Have secure part set to block the private contacts so you receive no random call/text. Turn it off when punt planning.
Emails goto secure part and set to no notification sound/ alert.
Perfect for me so far.
1 tip. Bmw's telephone system can't tell the difference so shows all your contacts
So. I have named them as Bmw then appropriate locations, Dudley,Brum, derby etc
If I do get a call and it someone gets through while I'm in the car I will tell the wife it's about the bmw recall.
Received a letter for a wire replacement that they will get in touch with me about.
I hope she ain't logged on this forum hunting me down lol.
Safer than a second phone as I have a works one as well, 3's a crowd on this occasion.
