How do I get a Snapchat+ Badge?

[AnnisHayma]

I’ve seen some users with a Snapchat+ Badge next to their name and I’m wondering how to get it. Do you need to subscribe to something, or does it unlock automatically after a certain level of activity? Also, does the badge appear instantly after subscribing?
If anyone has Snapchat+ and can explain the steps, that would really help!
