Iphone service plans including only unlimited text, calling, and image sending?

I haven't had real cell phone service in a while due to financial struggles. I'm really interested in just unlimited text, calling, and photograph sending. But would also like to have the capability to use the internet on my phone through my Wi-Fi at home. Only want to pay for the unlimited text, calling, and photo sending. Don't care to have internet access but at home through the phone. Around what price are these plans and would a Iphone be a good option or would I have to get a plan that includes internet if I get an Iphone?

What you want is unlimited text, calling and data, since image sending even when sent through TEXT (converts to MMS) which of course uses data.

So if you do not CARE about internet, you do not care about "photo sending" via text or apps that send pictures, because they all do so via DATA (another word for INTERNET) when you are talking cell phones. So unless you can wait to send all your pictures, AFTER you get home to use Wi-Fi, there will be no picture sending while out and about, unless you also have cellular data (internet) on the phone. '

So when you go to the phone store to talk about your wish list for a plan, DO NOT say anything about sending pictures to others or you will be saddled with a data plan, unless you make it 100% clear that you do NOT want cellular data. And then make 100% in the phone settings that cellular data is turned off, on the phone and on the cell phone company side, so that there's no chance that data will be used even by accident. I have this done for several friends that only wanted or needed voice and text, even with smartphones, because they were clear that they had no interest in data use on their phone.
