You can text people via phone number for free the only setback is you must already have been using it, or you will have to get a new phone number using your email, you can transfer other People's phone numbers onto the website and text them but you will have to log back in using email after the 20 minutes when the page closes. all text will be saved and you can go back and view them, you can also view photos. but unfortunately You can not send photos, view/send video and audio or send/receive calls. this is for Nintendo(Lite) i am not sure about any other device than computer and phone where the website/app works wonderful!
