I'm going on a cruise this coming week out of the country and I'm taking my phone along. I don't plan to use it much (maybe if I find a WiFi hotspot I would check email and such but thats it). My concern is that in case Visa decides to freeze my card until I call them back, I might have to make a phone call. If I turn on my receiver I don't want a ton of text messages and other things rolling in. My question is: Are there any settings or apps (I'm rooted) that could turn off everything except the phone radio? And does this stop texts from rolling in?
