Is there a WhatsApp addon to form a WhatsApp huddle wherein non-users of WhatsApp can receive messages by SMS?
No, whatsapp is an app. to put it simply for you, it would be like trying to send a sms from facebook or msn messenger.
i do not recommend using whatsapp for reasons stated by others. please be aware what an app has access to BEFORE you install it, once it's installed and got your information there is no getting it back from them.
TIP: most major smartphone operating systems have their own proprietary messaging service that you can use to send messages to other people on the same OS for free.
for example apple products (ios) have imessage which works through the standard messaging app built in and can send free messages as you normally would a txt to and iphone, ipod touch, ipad etc. simply send the message to the persons 'apple ID' instead of their phone number (you type the apple id in the box where the phone number usually goes). your apple ID is usually the email address you use to log into apple/itunes, NEVER give out your password to anyone or any apps.
hope that helps,
Almost all apps are like that
No,this is not WhatsApp works like that.The idea was to provide users a way to communicate with each other without paying SMS charges.Two parties must follow same protocol while communicating with each other.
you cant do that not possible right now
WhatsApp breached data privacy laws by storing non-user contact details
No, whatsapp can send messages only to those who use the app, the messages are stored in the server and are used by the whatsapp app much like email, except that it is instant unlike Email.
No you can't ! That's the answer for the question :)
