Umm....why not just call your friends?
How can I persuade my parents to let me get Snapchat? - they don't really like social media but it is hard to get hold of my friends on other sites.
Why don't you ask them about Skype ? Easy enough to monitor and more privacy. They could see or hear when you were talking with your friends and that might work out better for you.
Hi! Skype is your best step! :D
