Black Friday’s electronics deals are legendary, so we’ve rounded up the best Black Friday cell phone deals we’ve seen so far. More deals will be added as promotions are released.

One of Sprint’s better Black Friday deals this year offers 50% off the new HTC Bolt handset, which retails at $600. The Sprint deal requires activation of a new line of service, and you’ll have to pay off the phone in 24 monthly installments. Valid Nov. 24-25.

T-Mobile is promising a free Samsung Galaxy S7 on Black Friday weekend in exchange for a qualifying phone trade-in. Plus, you get a free virtual reality headset, the Samsung Gear VR. You can sign up for, or already be on, the new T-Mobile One plan and trade in a Galaxy S6, Galaxy Note 5 or “other qualifying device.” Details on what else qualifies are scarce. You can get the deal if you’re still on the discontinued Simple Choice Unlimited plan, as well.

The T-Mobile Black Friday deal requires you to pay for the S7 with a 24-month financing agreement, but T-Mobile credits your bill for the monthly cost of the phone, making it free as long as you stay with the carrier for the full two years. Offer valid Nov. 24-27.

If you buy a 256 gigabyte iPhone 7 from Best Buy, you’ll get a $250 Best Buy gift card. The 256GB phone is listed for $1,069.99 on Best Buy’s website. Buyers of the 32GB or 128GB iPhone 7 also will get gift cards, for lesser amounts. You’ll need service with Verizon, Sprint or AT&T, and you’ll need to pay for the phone with installment financing, likely for 24 months. Offer valid Nov. 24-26.

Best Buy is offering a similar deal on the Samsung Galaxy S7 and S7 Edge: a $250 gift card in exchange for a phone financing deal and service on Verizon, Sprint or AT&T. This offer also includes a free Samsung Gear VR headset.

If you want to buy an unlocked Galaxy S7, one not tied to any carrier, Best Buy will offer those for $120 off the usual retail price of $669.99. Offers valid Nov. 24-26.

Wal-Mart’s Black Friday deals also include a $250 gift card when you buy any Apple or Samsung phone, provided you pay off the phone with a monthly installment plan from AT&T or Verizon. The offer doesn’t apply to the Samsung Galaxy J3 and may not be valid for the entire Black Friday weekend.

Get a $250 Target card when you buy and activate an iPhone 7 or Galaxy S7 — including an S7 Edge — on Verizon, AT&T or Sprint. As with the previous deals, you’ll need to pay for the phone with a monthly financing plan, likely 24 months. Offer may not be valid for the entire Black Friday weekend.
