Nokia Phones in 2025: The 6820, 2720 V Flip, 'Infinity' Builds, and How to Reset a Nokia

I'm a procurement manager at a 420-person logistics company. For the past 7 years I've managed our mobile device budget—about $130,000 a year in phones, accessories, and repair contracts—and documented every order in our cost tracking system. The sideline that funds my own Nokia nostalgia is buying old phones, factory resetting them, and reselling them. So the questions below aren't pulled from a support forum; they're the ones my team and my collecting friends actually ask, and the answers come from money I've spent. Read the Infinity answer before you buy anything.

1. What was the “Nokia phone from 2000” everyone’s actually looking for?

When I first started searching for the “nokia phone from 2000,” I assumed the Nokia 6820 was from that era. It isn't. If you're actually remembering 2000, you're picturing the 3310 or the 6210—the indestructible bricks that showed up in every pocket, every movie, and eventually every antique phone collector's shelf. The 6820 came later, in 2004. From the front it looked like a normal candybar, but the screen twisted open to reveal a full QWERTY keyboard. It had a VGA camera, Bluetooth, and Series 40 software. In my opinion, that twist mechanism is more interesting than half of today's foldables. The problem is age: a “mint” 6820 in 2025 is still a 21-year-old machine. I've bought two “mint” units, and both had cracked flex cables under the keyboard. Parts are cheap. Patience is not. Treat it like a collectible, and budget $30–60 for a repair before you click buy.

2. Is the Nokia 2720 V Flip worth it in 2025?

To be fair, the 2720 V Flip got a rough reception when it first came out. KaiOS isn't going to replace your smartphone—you get WhatsApp, Google Maps, and YouTube, and that's more or less it. The 2024 refresh improved the hinge, made VoLTE more reliable, and the buttons are the best tactile feedback I've felt on any phone in years. From a total cost standpoint, it's pretty good: user-replaceable battery, standard USB-C, and very little inside that's begging to fail. I'd argue it's one of the best “slow down” phones you can buy in 2025. My one warning: check network bands before you purchase. A flip phone sold for one carrier doesn't always play nicely on another. A reset won't fix coverage. VoLTE support isn't automatic until you put your SIM in and make a call.

3. What's the deal with “Nokia Infinity” phones?

Here's the question that surprises people: “Nokia Infinity” is not a Nokia product, and it's not made by HMD Global—the company that licenses the Nokia name for phones. It's a name used by independent builders who create custom phones that look like retro Nokias with modern internals—big on YouTube, popping up in secondhand marketplaces. I have mixed feelings about them. On one hand, the craftsmanship is genuinely impressive. On the other, they're unlicensed, supported by nobody, and priced like collectibles—$400–800 in the listings I've tracked. I almost bought one for $430. The upside was owning something nobody I know has ever held. The risk was zero warranty, unknown internal parts, and no official software updates. I kept asking myself: is $430 worth potentially $430 down the drain? Per FTC advertising guidelines (ftc.gov), product claims have to be truthful and substantiated. So if a listing says “hand-built with genuine Nokia parts,” ask for photos of the internals and a supplier receipt. If they won't provide it, walk. As a conversation piece? Fine. As a daily phone? Don't.

4. How do you reset a Nokia phone?

How you reset a Nokia depends on the software, not the logo. For a 2720 V Flip or any recent KaiOS Nokia: Settings → Device → Reset → Factory reset (the wording varies slightly by KaiOS version). It'll ask for confirmation and your lock code. For a Nokia Android phone: Settings → System → Reset options → Erase all data. If the screen is frozen or the phone won't boot, power it off, hold Power + Volume Up, and select wipe data/factory reset in recovery. For classic Nokia feature phones from the 2000s, the route differs by platform. On Symbian/Series 60 phones, dial *#7370# and press call—that's the format code. On Series 30/40 feature phones, look in Settings → Restore factory settings. Default security code is 12345 on most. One thing a factory reset doesn't fix: carrier locks. If the phone is SIM-locked, a reset won't unlock it. Check that before you buy, not after.

5. Where should you buy a used Nokia without getting burned?

After comparing 8 vendors over 3 months with a TCO spreadsheet, I can tell you the cheapest listing is rarely the cheapest phone. Three things matter: condition, battery, and return policy. “Fully tested” should come with a screen-on photo. “New battery” should come with an answer about whether it's original or aftermarket—aftermarket batteries in old Nokias are a gamble, and a few are fire hazards. A seller who charges $5 more but takes returns is cheaper than a no-returns seller, because when a $100 “mint” phone arrives with a shattered LCD, the no-returns seller keeps the phone and your money. The vendor who lists all fees upfront—even if the total looks higher—usually costs less in the end. I've learned to ask “what's NOT included?” before “what's the price?” That single question has exposed missing chargers, fake “never activated” claims, and a “mint in box” that was a shell with no internals. Also budget $8–15 for shipping. A phone in a bubble mailer is too thick for a USPS large envelope—flats max out at 0.75 inches (USPS Business Mail 101, pe.usps.com)—so it ships as a parcel.

6. How much does owning a Nokia phone really cost?

Not the sticker price—the total. In my tracking system, a retro Nokia's true cost breaks down roughly like this: purchase 40–50%, battery replacement 15–20% (a 20-year-old battery is dead or swelling), charging accessories 10%, and repairs the rest. The 2720 V Flip keeps TCO honest because parts still exist. The 3310 is fun until you need 4G. The Infinity build is the worst TCO—not because it's expensive, but because its parts won't exist in five years. When I audited our 2023 fleet spending, I found that a $120 flip phone that lasts four years costs less than a $400 smartphone that needs a new screen by year two. I still kick myself for clearing out the storeroom in 2021 and throwing away nine classic Nokias that would have sold for about $1,200. Now I reset, test, and list them. Buy what you can actually maintain.
