antaeusa: I can spend up to $200 so might as well get a decent phone because the company pays for it)
Perhaps, but why waste the money on things like a touchscreen that will only waste battery when you already have an S3?
What line of work are you in? Perhaps a rugged phone would be a better use of the budget.
Or even just a decent non-smart phone that is going to last the distance (and the day).
Many of the 'smart phones' in your price range suffer from appalling battery life, are slow (because they are low on RAM) and really have no spare internal memory to do anything useful anyway.
Is perhaps another option to port your current number to your work plan, and just use it with your S3?
