Both things, mainly the second you are right. And I had the private box of go sms pro for this, but it is not working on my new phone with Android 4.04 (see my post Go sms pro private box: not working cause of the +1 area code
) . So basically I am looking a for a easy switch (texts on-texts off) that is provisional and allows me to retrieve the texts when the switch is on. And I do want to receive calls, so flight mode is not an option.
