Hello. We warmly welcome you to Android Forums. Now lets get started with your issue. It is most likely an error with your service provider (Sprint, Verizon, AT&T, etc.). Text messaging issues are rarely the issue of the phone, as the service and applications on android are fairly robust. It will be best to dial 611 on your handset and let the kind representative know what your issue is. They should have you fixed up that call. If you still have the issue, feel free to re-post your question with more info and the inclusion of what your representative for your carrier tells you.
