In other countries, incoming calls and text messages are free. It would be nice if they were free on Ting. This is especially true in the case of text messages because receiving text messages is either all or nothing in the case of phone numbers you don't know. You can't elect to ignore an incoming text message like you can a phone call.
"In the US, it’s the norm for both the sending and receiving parties to be charged for a call. But nearly everywhere else in the world, only the person who originated the call actually pays."
