Two big service providers in Canada have started charging customers to receive txts. This has angered a lot of customers, those on payg have left and those on contract are filling lawsuits against the companies.
I'm with the customers here, if I was charged to receive texts I certainly would go else where. Not just because the company can gain profits for spamming you, but that's not how the phone system works. If you phone someone the person that wants to get in contact pays not the person who is answering the call. At least with phoning you can reject the call. You can't with a text message.
