I'm thinking about buying this phone
and simply putting my current SIM card in it. I had been looking on AT&T's website at their phones, but every phone I chose told me I needed to upgrade my voice plan.
If I buy this phone will I be able to keep my current plan and not pay the $40 upgrade fee, or will AT&T lock me out and prevent me from using it? To switch plans would cost me an extra $25 per month. Over a 2 year period I would pay an extra $600 which is more than this phone would cost me without a contract.
