The data pro plan for an AT&T AirCard is $50 a month, for approximately 5 GB of data. The air cards themselves also range in price, with some costing under $50 and others over $150 as of 2015.
The base price of a data plan using an air card is $50 as of 2015. However, consumers looking to increase the amount of data they want with their portable hotspot will see an avid increase in price. Users that use more than the amount of data associated with the account will be expected to pay overage fees. Each air card component also requires a 2-year contract to be signed, prior to its use and purchase, to obtain it at that price.
