The Target $20 off $50 coupon
is a near-perfect match with the FreedomPop 12-month LTE SIM [target.com]
, which gets you 1GB of data and unlimited talk/text (via VOIP app) each month for 12 months on AT&T. This is a good solution for people already familiar with FreedomPop's free LTE service which was just axed from 700MB free to 250MB each month (starting now or with your next billing cycle).
A filler item is required to bring the total over $50. I suggest picking something you'll actually use from travel sized toiletries [target.com]
You'll additionally pay an E911 fee which varies by state, as well as state sales tax where applicable. Total in my state was about $33, or about $2.75 per month for the FP service.
