If, by "text messages", you mean SMS, then the answer as far as BlackBerry is concerned is no. SMS are a voice-only level of service, and never traverse any of the BlackBerry infrastructure.
If, by "text messages", you mean BBM, then the answer still remains no as far as BlackBerry is concerned. BBM is a peer-to-peer messaging system, and the BlackBerry servers are not involved in the process of those communications.
