A:AnswerThe SIM card is a separate purchase from the pre-paid unlimited data plan. You'll have to purchase one month of the pre-paid unlimited data plan of your choice (upon installing the SIM) to get things started. Plans change, so I suggest checking out the latest offerings at: https://www.att.com/prepaid/plans.html Also, be sure to read the footnotes in the chart at that web site.
The folks at Best Buy set things up for me for one of the pre-paid plans when I purchased a new smartphone. The one-month pre-paid fee was charged to my credit card.
A:AnswerI'm on the ATT pay as you go plan. I pay $30-35 a month for phone service and I get 1GB of data. I can add an extra 1GB for $10 each. I've been NYC and the coverage was excellent there. There might be better options for you, but that's my two cents.
Alternatively, if you want to switch to ATT permanently they have a limited time promotion. Phone service and 8GBs of data each month for only $25 but you have to pay for the full year upfront to get the deal. I'll probably change my plan to this soon.
