The monthly device charges for the Samsung Galaxy S10e drop from $20 to just $1 when you get one on a 30-month installment plan and open a new line of service with an Unlimited plan at AT&T. Over the course of the plan you'll have saved $570, which makes this the best deal we found for the S10e on any carrier by at least $400. As a bonus, add a pair of the new Samsung Galaxy Buds+ to your order and their price will automatically drop from $150 to $100. That's the best price for a pair by $50. Shipping is free. Sales tax is charged in most states.
