I am currently unable to get incoming text messages... I think it might have to do with a US add on package that I bought.. it was good for 10 days.. I stopped getting incoming text almost exactly 10 days to the hour since I first added on.. I am back in Ontario now....messages were working fine the past few days.
So it is working now? usually it will resolve it self. and restart might help.
It is a known issue for some customers with us roaming addon.
