I use Microsoft LUMIA 540. The only chatting app which I could use in it is Whatsapp. When will it support apps like snapchat, kik. There is also an KIK app in store which will never installs.
There is a petition for Snapchat which has over 57k signatures. So there's a pressure. Other than that it's impossible to answer your question due to the fact that both companies haven't made an official announcement regarding the matter. Let's hope soon.
