The investigators are testing whether patients with diabetes can communicate with our health care system through text messaging. The investigators will look at how often they respond to prompts for blood pressures, blood sugars, and step counts. The investigators will also see if they come in for lab tests when prompted by text message. Also, for patients overdue for medication refills, the investigators will ask them why they have not yet called for the refill.

Patients will be sent text messages through a software interface, the Patient Relationship Manager (PRM). A registered nurse will also use PRM to receive incoming responses. Tasks will be created for her to outreach to patients who have out of range text responses or poor response rates. This intervention if a feasibility study to see if patients can communicate with the investigator's health care system and potentially utilize PRM to better manage their diabetes.
