SMS/imessage vs data? Need clarification?

I have an iPhone 5s and this question may seem a bit stupid to you, but I need some clarification. I don't have a data plan so I message with iMessage when I have Wi-Fi. But I also have unlimited texting which I didn't think mattered unless you had a data plan. So if I turn on SMS, can I text when not connected to Wi-Fi and it will just cost me the unlimited texting money or is it separate and I will have to pay more? Also, I know you can't message anyone without an iOS device when using plain iMessage, but if I use SMS, can I text any other phone that's not IOS and it will not cost me anything other than the unlimited texting?

Do you enjoy reading the news, or books, or both?

So I just started reading the news on my phone. I've got an Iphone with a couple news apps, and send articles I want to read later to my Instapaper account. I truly enjoy and feel like I'm becoming more informed, plus building my reading chops lol. I've thought about starting to read books, however I feel that with my short attention span, I will never get through a book, or I will just become aggravated with my slow reading. Anyway do you like reading the news or books, or both, and should I start reading some books if so give me a suggestion, Thanks Ill pick best answer.

Can my iPhone avoid water damage?

So I just dropped my iPhone 4s into the toilet… It was before I sat down, so I got it out in literally a second and dried in 3 seconds. It was on when I dropped and it seems to work fine still right now. I was kind of slow to dry out the headphone jack and the charging port.

Should my iPhone be ok, and when would it be safe to charge it again?

Will AT&T charge me if I put my sim card into an iPhone?

I'm currently using a Pantech Link II right now and my two year plan with AT&T has recently expired. Even it expired I still didn't upgrade yet. I have an unlocked iPhone 3gs and I was wondering if I put my sim card into the iPhone will I get charged for data? My pantech that I have now does not have internet so the data is blocked. If I turn off the data and everything on the iPhone will they still charge me? I know that they know that I'm using a iPhone. I was just going to be using the phone like a regular phone and use Wi-Fi instead of their data.
