How much on average a month having an iphone 4 for verizon bill cost me?

A friend of mine is giving me her Iphone 4 (she upgraded) and since I have tmobile, I would have to switch plans, so how much would it cost me a month? Say I had a 6gb package, i currently use a lot of data and internet access, unlimited talk/text on my tmobile plan.

Atleast $70

Honestly it's best to contact the service provider and go over your options. Depends on how many minutes a month you want, free evenings and weekends, texting limitations, call waiting, etc. Then there's different data plans. We couldn't give you a complete accurate answer considering we don't know your complete preference. You can call customer support toll free and get the full insight on the matter

You could just unlock the phone and use your current plan.

6 gb on verizon would be around 130 a month

you can flash it to boost

$40 for the smartphone with unlimited talk and text.

$80 for 6GB of data.

25% to 30% for taxes and fees. Where I live the taxes and fees for a Verizon phone are 25%.

$40+$80=$120
$120x.25=$30
$150 per month, possibly more depending on where you live.

120 plus 12
Half of the 12 to your state
Half to verizon for free
