In the U.S., two of the big four carriers will be selling the OnePlus 8 — not the OnePlus 8 Pro — starting April 28 at 9 p.m. PDT: T-Mobile and Verizon. The self-proclaimed Un-carrier intends on making a splash with the new launch by giving away phones to its subscribers and rounding up as many switchers as possible with big discounts on both the 8 as well as the 7T.

New and existing customers are able to get $350 off a 128GB OnePlus 8 (half-off after discount) or the LTE-equipped OnePlus 7T ($150 after discount) where stock is available if they start or add a line and then sign onto a 24-month installment plan — the discount comes in monthly credits. If you canceled a line within the past 90 days, you'll need to add two lines.
