Greetings all,
I've just upgraded my iPhone 4S to iPhone 6. I had a very old unlimited data plan ($30) and 1000 text messages ($10). My plan was 450 Nation with tons of saved minutes ($39). My monthly bill was between $85 - $99, due to overages (international text messages).
I pre-ordered online (AT&T) and when I activated my iPhone 6, I immediately lost my data and message plans. I could call CS or go to AT&T store and spend few hours to get my unlimited plan, however I decided to save my time and pick limited data plan.
My average monthy data usage is 450MB, my max was 0.9GB (only one time for 4 years). I chose Mobile Shared Value plan - 1GB, unlimited voice, unlimited text (incl. international!) for $25 + $40 smartphone = $65 total (about $69 with taxes and surcharges). So I am saving between $15 and $30 a mont.
Is there a catch? I'll come back in a month or so to update with my experience.
