To get the Subscribe button, you’ll need to convert your profile to public. The option to convert your profile is only available if you’re over 18, have had your Snapchat profile for at least 24 hours, and have at least one friend on Snapchat (a person you follow who also follows you back).

Once you tap Create, you’ll have a new public profile to customize. The Subscribe button appears on this profile instantly.
If you ever decide you no longer want to have a public profile, you can delete the profile without affecting your Snapchat account. Just return to your public profile editing screen, tap the gear at the top-right, then tap Delete Public Profile.
You must have a public Snapchat profile with at least 100 subscribers. Your profile must be at least one week old. You’ll need at least one bi-directional friend—a relationship in which two Snapchatters have accepted one another as a friend.
There are many theories about how many views you’ll need before Snapchat considers you a Creator. Even though Snapchat says you only need 100 subscribers, many users claim it takes thousands of views (not just subscriptions) to get noticed by Snapchat. To increase both your views and subscribers, focus on creating the type of content that people will want to share with others. Promote your Snapchat on social media platforms on which you already have a following, such as Twitter and Instagram. Engage with the Snapchat community. The more rapport you build with others, the better the chances that Snapchat will recognize you as an influencer.
