Added unlimited texting to my cell phone a couple years ago because my kids seemed to prefer texting over calling and their plans had unlimited. They were putting me over my max most of the months, even though I told them I was not paying for unlimited. Kids! LOL. I bit the bullet and switched to the unlimited plan. Well, I have since switched to the iPhone. One daughter had an iPhone and her texts changed to blue. My other daughter just got an iPhone month ago. Now her texts are blue. My son got an iPhone yesterday and his texts are blue. They are the only people I text with. Since they are all blue, and also show up on my iPad, can I cancel the unlimited text through my carrier and just go back to that minimal amount for the occasional random text from my sister? I am assuming the blue texts are not using my cellular plan, but rather are Apple messages that are completely not related to my cellular text plan? They all appear on my iPad also, so I am assuming they are not using my cellular plan's text messaging. Not asking for phone support, I will be contacting my phone provider, I am basically just making sure that my understanding of the blue texts is correct in that they are not using my cellular text plan before I do this. Am I correct? Thanks.
