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

Samsung Galaxy S25 series: $900 instant trade-in credit and up to $300 credit at Samsung
Looking for an unlocked device? This right here is your best option by far. The official Samsung Store is offering an excellent trade-in rebate of up to $900 and $300 of store credit on the house for both carrier and unlocked devices today. The trade-in here is superb and the $300 credit is also a significant bonus that can be used to pick up any number of cheap accessories at the Samsung Store. Overall, a superb opening deal and one that's even better than I anticipated.

Samsung Galaxy S25: free with a new unlimited line, plus free Galaxy Watch and tablet at Verizon
Verizon's current deal on the Galaxy S25 is actually a step-up from what it was initially offering. You no longer need a trade-in to get the standard Galaxy S25 for free alongside a new line on either a Plus or Ultimate plan. On top of that, you can also throw in a free Galaxy Watch and tablet as bonuses here if you're willing to pay a bit extra for their cellular lines. One of the biggest advantages of this particular deal is that it's available on both the Ultimate and Plus plan - the latter being the mid-tier option that's usually been excluded from deals like this up until now.

Samsung Galaxy S25 Ultra: $5/mo with a new line at Verizon
More interested in the higher-end Galaxy S25 Ultra? The good news is that Verizon has also recently waived the trade-in eligibility on this particular device recently if you'd prefer to get a straight-up monthly discount. Available currently is a whopping $1,199 saving on this device, which brings the monthly cost down to just $5/mo over the duration of 36 months. Note, however, that you will need a new line on the pricey Ultimate plan to be eligible for this deal.

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.
