My AirVoice contract says data won't be turned on unless I call them to make it happen. That said, I noticed that it seemed like data was on. I got a bit worried so I turned it to airplane mode just to make sure the phone was not accidentally doing something I don't want to pay for.
For the texts-from-others question, I explained to one person that I am on this reduced plan and it'd be great if they could compress texts. They took this pretty well, I thought.
For the spouse, I reminded him that I can't get the internet a few times. Also, I had to explain I can't receive MMS so to please email me photos instead.
I usually use texts to meet up with people or send a random hello. In sum, I do not get many texts.
I need to get Google Voice--or something--set up at home, because I miss talking with people.
