Well, tell me one thing did you get charged by the service provider for those 10messages ? I mean if your getting charged for those 10 messages then I would say try doing a soft reset of the settings over your device and again if that doesn't solves the problem then i would say walk over to the nearest customer support for fixing it up ! and if you are not getting charged for the same then I don't think there is anything to worry about it's the problem with your carriers, I would say better to talk to your carrier for fixing it up.
