Today's best Samsung Galaxy S25 deals: free devices, accessories, and massive rebates

Samsung Galaxy S25 Ultra: free with a new unlimited line, plus free Galaxy Watch and tablet at Verizon
Verizon's current deal on the Galaxy S25 Ultra is easily the best yet from the carrier. For the first time ever, no trade-ins are needed to get this extremely premium device for free alongside a new line on an unlimited data plan. On top of this, you can also throw in a free tablet and smartwatch if you're willing to pay a little extra for the cellular lines. The only catch here is that you need a line on the priciest Ultimate unlimited plan to get the Ultra for free, although both the Plus and Galaxy S25 are similarly available on the slightly cheaper plans.

Samsung Galaxy S25 series: up to $1,000 off with a trade-in at Samsung
The Samsung Store has been offering solid Galaxy S25 deals for a few months now but unfortunately the party had to end sometime. Right now, its trade-in rebates of up to $1,000 are OK but they're not quite as generous as the offers before. Previously you also had an option to instead go for a $300 upfront discount, which was just a flat-out great all-around option for those not looking to line up a trade.

Samsung Galaxy S25 series: get up to $1,299 off with a trade-in, plus cheap watch and tablet at AT&T
AT&T's opening Galaxy S25 deals offer a compelling combination of a decent trade-in rebate and the option to bundle in a Galaxy Watch 7 and Samsung tablet for just $0.99 per month each. As always, the trade-in rebate is the bulk of the deal here since its maximum saving of up to $1,299 is enough to cover the entire cost of every device in the range. Note, that you need a 36-month unlimited plan to be eligible for the saving, although I expect the trade-in eligibility criteria to be pretty generous.

Samsung Galaxy S25 Plus: get a device and unlimited plan for $65/mo at Boost Mobile
If you're looking for something a little different from the usual trade-in / expensive plan deal, then consider Boost Mobile's Infinite Access plan. The carrier offers the Galaxy S25 Plus alongside an unlimited plan for just $65/mo - a deal that doesn't require that usual trade-in to be eligible. While the plan here isn't as feature-laden as some of the higher-end options at Verizon and the like, this is a very cheap option - and Boost Mobile will also throw in a free upgrade when the time comes, too.

Samsung Galaxy S25 series: up to £660 off with a trade-in at Samsung
While you can no longer get your hands on the excellent storage upgrade that Samsung was offering as part of its initial preorders promotion, the official UK retailer is still offering an excellent trade-in rebate of up to £660 off. This remains the cheapest way to get an unlocked device in the UK so it's a strong recommendation, even if this deal isn't quite as complete of a package as previously.
