From Argentina only: Testers for an appication test

General information for the app: The app enables you to send massages or phone others via internet
Extra notes: My agency is looking for people registering on our website from Argentina - however we need some expertise for the Argentinian Market and some knowledge if there are special platforms for students in Argentina or any other popular platforms.
Please make sure that you fit in the requirements: for participating you have to use or have access to a SIM card from Movistar.
The applicants needs to have a knowledge of online platforms and communication in Argentina and shall help to provide ads that lead to conversions.

Another possibility is to identify blogs in Argentina on which we then could pay for blog marketing.

Keen on your ideas!
