I've got a bunch of damaged iPhone 4's some of them arrive unactivated so one of the first things I do is activate them with iTunes to see what kind of working order they are in.
To this end I purchased a brand new Vodafone microsim the sim has no credit on it and if I leave the sim in the phone eventually I'll get a txt from Vodafone telling me I don't have enough credit to send a txt message which is odd because I haven't sent any txt's.
It's happened with all the iPhone 4's I've activated and left the sim in the phone for a bit. I can't tell what the contents of the txt is or who it's going to. Only thing I can think off is that there is some kind of secondary activation with Vodafone for the microsim?
Can anyone shed some light on what this mystery txt is?
