Customers switching to AT&T and keeping their current phone can save up to $360 per line over 36 months when adding up to four new lines. Important Loyalty & Scam Warning

The "free" price is usually delivered via monthly bill credits over 36 months; canceling early makes the remaining balance due immediately.

Under the Premium 2.0 plan , users can receive a 50% discount on any smartwatch or tablet line for each phone line on the account.

While there is no current official promotion titled "Buy X Get 8 Free," AT&T is running several multi-line and "on us" deals that allow customers to get multiple devices or lines at significant discounts or no cost. Based on current offers from AT&T Deals , the closest available options involve high-value trade-ins or business-specific multi-line incentives.

Even on free devices, you are typically required to pay the full sales tax upfront based on the full retail value of the phone.

Be cautious of unsolicited calls or texts offering extreme "loyalty discounts" or "buy one get X free" deals. Reportedly, scammers have been posing as AT&T representatives to offer fake 25% discounts to gain access to account details. Authentic AT&T offers are typically found directly within your customer portal on the official AT&T website .
