Text Messaging Play a Vital Role in HealthCare Sector. The highly regulated healthcare industry can certainly stand up informational mobile sites modeled on their wired Web sites. A major utility is the use of SMS to alert opted-in consumers of the next refill of their prescription. This alert can come from a pharmacy such as CVS/pharmacy or Walgreens or from a pharmaceutical manufacturer such as Pfizer or Johnson & Johnson. Pharma companies can also offer allergy information on their mobile sites and via text messages. SMS is the best tool for pharma companies simply because some patients -- the elderly, for example -- may not care much for fancy mobile stuff. But given the fact that 99 percent of mobile phones nationwide have SMS, the channel is ideal for delivering refill reminders or health alerts.
