OnePlus 8 5G, Locked to T-Mobile | Black, 128GB, 6.55 in, Batt 90%+ | Grade B-
Used
Why we picked it #1
This T-Mobile locked OnePlus 8 stands out for value—it’s one of the lowest price listings near the top of what you’ll see for condition. You’re getting 128GB of storage and a battery with over 90% health, which is great for a device of this age. That means you can expect reliable daily performance and a battery that won't leave you stranded mid-day. Compared to the fully unlocked listings, you’re saving around $15–$25, but the tradeoff is it’s locked to T-Mobile—if that’s your carrier, this works out perfectly, but you can’t use it on AT&T or international SIMs. Also, it includes a non-OEM charging cable (not original), and stock photos are used, so you aren’t seeing the exact device—if you care a lot about little scratches or unique blemishes, that’s worth noting. All told, if you're already on T-Mobile, this is an excellent mix of price, strong battery health, and solid condition for the money.
OnePlus 8 5G, Fully Unlocked | 128GB, Black, 6.55 in Screen | Grade A | IN2015
Used
Why we picked it #2
Choosing this fully unlocked OnePlus 8 gets you more flexibility and peace of mind—the phone will work on any compatible carrier, and it's graded as 'A' condition, so it's likely to look and feel fresher than the cheaper options. Battery health is up there at 90%, so you won’t have to worry about charging midday. This is the pick if you want to avoid carrier headaches and want a device that feels close to new, but you’ll pay a bit more than the T-Mobile locked or slightly more worn options. Tradeoffs: No charging block included, photos aren’t of the actual device, and there’s a restocking fee for non-defective returns, which isn’t ideal if you’re the type to change your mind. Still, if you want the least risk and widest compatibility, this is the safest play—you're paying a little more, but getting peace of mind.
OnePlus 8 5G, Fully Unlocked | 128 GB, Gray, 6.55 in Screen | B- Grade | IN2017
Used
Why we picked it #3
This listing is a mid-priced, fully unlocked option that saves you a bit compared to the top pick. You’ll get 128GB of storage and the flexibility to use the phone with any compatible network. The big tradeoff is cosmetic wear: it's a B- grade, so expect visible signs of use—scratches or scuffs could be present. Unlike the top listings, you won’t get the same 'like new' look, and the battery health isn't specified, so there’s a little more uncertainty there. Photos are stock, not the exact device, and there's a restocking fee if you return it for any reason other than defects. If you’re okay with some wear and want full carrier flexibility at a discount, this is a practical pick—just set your expectations on looks, and try to confirm battery life with the seller if that's important to you.
OnePlus 8 5G UW - IN2019 - 128GB - Gray (Verizon) - Very Good Condition
Used
Why we picked it #4
If cost is your main driver, this Verizon-locked OnePlus 8 is by far the cheapest option that still ticks most practical boxes. You’ll get 128GB of storage—a solid baseline for apps and photos—and it’s listed as 'Very Good' overall, sold by a top-rated seller and shipping fast. The big catch is that this is only for Verizon users—the phone won’t work on other networks. Battery health is a real downside at 78%, so you’ll probably find yourself charging it more often, and the original charger and box aren’t included. There are some small nicks on the edges too, but that might be a fair trade if you want maximum savings and don’t care about minor cosmetics. In short: if you’re on Verizon and can live with an aging battery, you won’t find a better price.
OnePlus 8 5G IN2017 T-Mobile Unlocked 128GB Interstellar Glow C
Used
Why we picked it #5
This listing gives you a T-Mobile unlocked OnePlus 8 in the eye-catching Interstellar Glow color, and you'll get decent seller support and data sanitation for peace of mind. The price is reasonable, sitting comfortably in the middle, and you get 128GB of storage—same as the other top options. The main compromise here is battery health—it’s at 78%, so you’ll need to charge it more often, and while it's functional, the cosmetic grade is below the fully unlocked Grade A at #2 and #3. If you want an unlocked T-Mobile device in a standout color and don’t mind some cosmetic flaws or a battery that’s showing its age, this strikes a nice balance between cost, condition, and carrier flexibility.
