ONLY KNOWN FOR TELUS USERS: It's a memory issue in most cases. If you have too many applications downloaded or too many photos/video/music, it will focus the memory more on those than your texts/calls. Try either moving your photos/movies/music to a memory card, delete the photos, etc. and then remove the card, and have a friend text or call you (don't answer the call). If that doesn't work you can try deleting some of the applications. Only ones you have bought. But, don't worry, you can get them back without paying again by going to the Telus Portal, hitting the menu button, click settings, and then purchases. Once it builds the list, you should be able to click on the application and re-download it. If none of those suggestions work, try contacting you service provider and see what they suggest.
