I use Go Launcher but not Go SMS
I use the standard messaging app on the HTC One X
If I don't set Go Launcher as the default Launcher then I don't have a problem, but if I do then the minute Go Launcher is started I get an SMS sent to my wife's phone, every time I reboot the phone.
If I use HTC Sense as the Launcher then I don't get the SMS every time I reboot the phone.
Also as my micro-sim is a replacement it does not have my number stored on it, so when you go to about and check it the information the number is reported as unknown, so it's a bit pointless sending a message saying new sim = null, new number = null as how is anyone going to trace that...
update: not sure but may have fixed this, but need some further testing - had to remove the anti-theft and then reinstall it while using Go Launcher as default launcher, so far after a few reboots it's not sent any messages saying it's a different sim card
