First, let me say that this is not Ting's fault... but want to get the community's feedback on my position/considerations...
So I signed up for Ting in September, bought a G3 (and a feature phone for my parents), and was off to the races.
I checked my account online regularly, and set up alerts to inform me when data or voice or messages went above certain thresholds... all fine and good. Even installed tasker to keep the device from syncing over cellular data and only do it over WiFi.
Then in November, I saw that on one day I had data usage - which typically runs in the 6-8 Mb range - had a 300+Mb day... I racked my brain, but could not determine that I had done anything differently than usual... I called Ting and they were unable to help me with why the usage had been so high. I checked the data usage as measured by the device itself and it showed much lower usage and no apps which seemed to be the culprit. Ting CS graciously credited me down a notch on the plans by giving me a $10 credit. I figured, "OK, one little bump in the road... no problem."
Then I noticed my behavior started changing... I waited until I got into wifi to check things like email and fb. I didn't stream any videos or other things that I was concerned would 'eat' into my bucket of data. Things I would not have worried about with an unlimited plan (even a throttled one).
And then this past weekend, I made a big boo-boo. I accidentally uploaded 2.7Gb of photos to Picasa from my device... well, accidentally isn't the right word... but I didn't think about it right away... when I did a minute later, I tried to cancel the upload - obviously I failed. To make matters worse, I think I actually uploaded 2x because it didn't seem to start the first time I tried.
So now I am hit with a fairly substantial data bill this month. And I find myself 'scared' to do things on my sexy new S3.
So I'm weighing the longer-term pluses and minuses w/respect to staying with Ting. On the one hand, my bill even this month is likely to be only on par with my previous unlimited plan. And this is 'probably' a relatively rare occurrence with me. On the other hand, I truly 'hate' the thought that one little button press (or 2 if i actually did it twice) cost me ~$60 in data charges. And it could happen again, i,e, if my 4 year old figures out my unlock code and spends an hour on YT or something like that.
I'll stress again... none of this is Ting's fault. I bought into the idea of a 'measured rate' data plan, after all. But for me, having to think about using the device before I actually use it, combined with the capability of a single action generating massive usage (something that's unlikely to happen with voice calls...) makes me question whether or not I should stay. 'Unlimited' is more powerful a word than I previously thought :).
So that's my story and my situation.
