Verizon's current Galaxy S25 deals are the best we've seen from the carrier this year. All three devices are currently available with huge discounts if you pair them up with a new line on one of the carriers' unlimited plans. In particular, the Galaxy S25 and Galaxy S25 Plus are available on the excellent value Welcome Unlimited plan, which is just $25/mo per line if you have four lines. Even the Galaxy S25 Ultra is avaiable with huge discounts of up to $1,000 off right now - although note, you will require a line on the higher-end Plus or Ultimate unlimited plans to be eligible for a discount on the flagship.

Samsung Galaxy S25 series: up to $200 upfront, or up to $700 off with a trade-in at Samsung
Samsung's current trade-in rebate of up to 700 off isn't one of the biggest rebates we've ever seen from the official site. The upfront discount of up to $200 off, however, is easily one of the better no-strings-attached deals we've seen for a while at Samsung, however, so this is still a fantastic option if you're looking for a slightly cheaper unlocked device this week.

If a trade doesn't appeal, then consider picking up the standard Galaxy S25 for just $10/mo alongside an unlimited plan. Finally, new customers will get an additional $200 in bill credits if they sign-up online.
