My Dad Blocks Text Messaging on His Phone

AS OF TODAY OUR CELL PHONE HAS BEEN BLOCKED FOR TEXT MESSAGES.
I noticed on a couple of recent Verizon bills that I had been charged for a text message. I have never sent a text, nor do I even know how to retrieve one, and the same goes for Mom. Therefore, I do not want to receive charges for an unused tool.

You can call me at any time (preferably not after 11:00 pm until 6:00 am, eastern time), but in an emergency you can call any time. I recently was awakened at 1:33am by someone looking for someone named Tanya. I should have told them that Tanya was in my bed and don’t disturb us again, but at that hour I was not too quick on the trigger.
You can also e-mail us because I can access that either here at home or away, and even on my “I Pad”.
Or if you are not in a hurry you can send me a letter or post card.
All calls and messages are cheerfully received and replied to, unless we forget.
Incidentally, I think all the texts we have received were junk mail from advertisers.
Best to you all and love from both Mom and me.
