As reminder device for medication & safer sex	"Using my cell phone is like having another arm. I always use the alarm function of mine [cell phone] to wake up in the mornings and I use it as a reminder [to take my pills]." Male, 39 years old

	"I think it's important [to use cell phones to receive prevention messages] because you can be updated and be prevented." Male, 48 years old
	"It has to get to you. Definitively. Even by chance, you always open your SMS messages, even by chance. And you might find something. You have to be obstinate; you have to be very incisive when you leave your clear message. For example: How is going everything? Did you take care of yourself" Did you use your condoms today? It looks like offensive or pushing, but it is a way to attack directly the problem and that people can listen to you. I'd prefer an SMS, and it should be incisive, rather than a pre-recorded voice message." Male, 34 years old

Male, 35 years
