Today I noticed what to me is unexplained behavior of text messaging. I normally keep the Cellular Data setting on my iPhone set to OFF (since I'm on the cheapest data plan and I want to minimize unnecessary cell data communication). Last night, I sent text messages out, both iMessage and SMS. I received some back. Earlier today, I set the Cellular Data setting to on briefly. When I switched it on, about two or three text messages quickly poured in. So, is it necessary to keep Cellular Data set to on in order to receive texts from certain users on certain providers, or perhaps even on the same provider as you in certain situations?
