After receiving an invite via SMS, the user can register his/her personal medical information in the Red Cross database, either by replying the SMS invitation or by entering the website.

In agreement with the carrier, the SOS SMS service is available as an emergency number, accesible through the emergency screen.

When a rescuer dials *SOS from the patient's cellphone, no sensible personal information is displayed, just gender, age, height and weight, to properly identify the patient. But important information is available to the rescuer, like blood type, allergies, medical conditions, pregnancy, medicated drugs, or any other vital data.

In the pre-launch stage 300,000 users were invited via SMS, since march 19th 2015.

So far, 40% have successfully registered their personal medical information in the Red Cross database.

The launch stage will be supported by a national media campaign, after which we expect to reach 80% of all the cellphone users in Mexico.

Every day the Mexican Red Cross attends more than 3,000 emergencies. In 5% of the cases, patients die for not having basic medical information available. Patients who are in state of shock or unconscious and that don't have a medical tag.

With the SOS SMS service, Red Cross rescuers can access the patient's medical information through the patient's cellphone, even in locked-screen mode. And so, any cellphone can become a tool to save it's owner's life.
