With My420Net IM, you can send messages, photos, videos and files of any type (doc, zip, mp3, etc), as well as create groups for up to 5000 people or channels for broadcasting to unlimited audiences.
You can write to your phone contacts and find people by their usernames.
As a result, My420Net IM is like SMS and email combined — and can take care of all your personal or business messaging needs.
Anyone on your phone's contact list that has this app will be allowed to send you a friend request.
This works with the contacts you already have on your phone. First thing you do when you open it is register your phone number and then it activates and lets you create your account.
So if you want a friend to add you then they have to already have you as a contact on their phone.
This makes this app very secure and private. You wont get messaged by any spam strangers at all.
