I blocked it, I still have old flip phone, Nokia, charge it once a week, small n light enough to hide in my pocket. I pay $50 a month for 2 lines and 600 shared mins, 11 year old plan!
I do not have any message plan and it costs 25 cents per message, every now and then people would send me a few and I didn't mind paying 2 - 3 dollars extra every month as compared to paying $10 to get a message plan, but then I started getting spams and two of my acquaintance started sending me messages a LOT, even after requesting them not to do it and their messages were really unimportant.
So here I am today, all incoming and outgoing messages BLOCKED.
