Nokia Phones in 2025: Banana Phone, 2720 Flip 4G & DuraForce Pro 2 — Buyer's FAQ

If you're considering a Nokia phone in 2025, you're probably asking the same questions I asked back in 2023 — before I'd wasted roughly $2,400 on the wrong devices. I manage device purchasing for a field services company, and in the past three years I've bought just about every Nokia on the market: for our team, for friends, and (let's be honest) for myself. I've documented every mistake so I don't repeat them. Here are the answers I wish I'd had.

1. Is the Nokia banana phone (8110 4G) worth buying in 2025?

Only if you know what you're getting into. The “banana phone Nokia” search is still going strong in 2025 — and I get it, the design is iconic. When I first picked one up in March 2023, I assumed a 4G Nokia would just work like any other 4G phone. That was my first mistake. The 8110 4G runs KaiOS. It's not a mini smartphone. You get calls, texts, a basic browser, and a handful of apps. That's it.

The second issue is network bands. The banana phone supports LTE bands 1, 3, 5, 7, 8, 20, and 28 — which works well in Europe and parts of Asia, but not everywhere. On some US and Canadian carriers, it drops to 3G more often than I expected. (Unfortunate, since I bought it specifically for reliable 4G calling.)

What it does well: battery life for days, a truly iconic look, and the best pocket conversation piece you can buy. Notifications are clear, the speaker is loud, and the build is impressive for the price. But as a 2025 daily driver? No. As a backup, a travel phone, or a digital detox device? Absolutely. Just check the LTE band list against your carrier before you buy. I didn't. Don't be me.

2. How do I unblock a number on my Nokia phone?

The honest answer: it depends on the phone, and the menus move around between software versions. On a Nokia Android phone, open the Phone app, tap the three dots, then Settings, then Blocked numbers. Find the number and tap the minus icon. Done.

On a KaiOS phone — like the 2720 Flip 4G or the banana phone — it's usually Settings > Call settings > Blocked numbers. But here's what I learned the hard way: some KaiOS versions put it under Privacy instead. I once spent 30 minutes on a support call telling a colleague to look under “Call settings,” while his screen showed “Blocked list” under “Privacy.” We were both right, but we were looking at different screens. Asking “what do you see right now?” would have saved us both the headache. (And yes, I did laugh at myself afterward. Ironic for a telecom company.)

If you get stuck, use the search bar in Settings. Type “block,” and most phones will take you straight to the right menu. This trick works on Android and KaiOS, and it's rescued me more times than I can count.

3. Nokia 2720 Flip 4G: what should I check before buying?

The 2720 Flip is the most sensible Nokia feature phone for 2025 — but “sensible” doesn't mean “no surprises.” I learned this when I ordered 10 units for our field team in Q1 2024. They looked great in the box. Then came the problem: VoLTE.

The 2720 supports VoLTE, but your carrier has to authorize it for your specific SIM. We tested one unit with a personal SIM, and it worked perfectly. Then we deployed the rest on corporate SIMs, and half of them couldn't complete calls. That was a $700 mistake, and it still stings. Check the IMEI on your carrier's compatibility page before buying. Not after.

Second lesson: the charger. The 2720 uses micro-USB. I handed one to a colleague who, in good faith, plugged it into a fast charger. “It's USB, it'll be fine.” It wasn't. Fried charging port, $45 motherboard replacement. My communication failure — I should have said “use the included cable only.” If you buy one, keep the original charger with it. Yes, it's micro-USB in 2025. No, there's no easy fix. Just manage it.

4. Should I still buy the DuraForce Pro 2 in 2025?

I wanted the DuraForce Pro 2 to work. It's a rugged Android device that looks perfect for field crews — military-grade, waterproof, shockproof. When I bought a used one in May 2024, I was genuinely excited. Then I checked the OS version. Android 10. No more security updates. Some apps won't update anymore, and signing into a corporate account feels like a risk.

That $180 second-hand deal became a $180 reminder that in 2025, an unsupported OS isn't a bargain. It's a liability. Also, the DuraForce Pro 2 comes in multiple variants with different 4G band support. I bought an international version that missed a critical band for our US network and had to return it. If you're looking for a rugged phone, get something current — the price difference is smaller than you'd think, and it's way cheaper than the hassle.

5. Is KaiOS really as bad as people say?

It's limiting if you expect it to be a smartphone. It's perfectly fine if you use it for what it's meant to do: calls, texts, light internet, and long battery life. KaiOS is the operating system behind the banana phone and the 2720 Flip, and it's designed for low-power hardware. Yes, the app store is small. No, you won't find your favorite banking app. And yes, heavier websites can feel slow.

But the people who complain about KaiOS usually bought the phone expecting Android-level functionality. I did exactly that. I tried to make the banana phone do everything my smartphone did. It struggled. It wasn't the OS's fault. It was mine. (A lesson that keeps repeating itself across 2025, honestly.)

6. So which Nokia phone should you actually buy in 2025?

Here's my short version, based on three years of mistakes:

• Nokia banana phone (8110 4G): for the retro fan, the detox experiment, or the conversation starter. Not a daily driver.
• Nokia 2720 Flip 4G: for calls, texts, and some maps. Check VoLTE before buying. Seriously.
• Rugged Android (like the DuraForce Pro 2): avoid old models with dead software support. Spend a little extra on something that still gets security updates.

The biggest mistake I've made — bigger than any individual phone — was focusing on the purchase price instead of the total cost. That $50 cheaper refurb cost me $140 after the battery gave out and the bands didn't match. The $700 VoLTE mistake saved me maybe $20 per unit at the start. Even worse, I saw the warnings in the specs and ignored them because I wanted to believe it would work.

Take the extra 15 minutes: check the network bands, check the OS support status, and read the real-world reviews. It would have saved me thousands of dollars and a fair amount of embarrassment. I keep this checklist in my notebook, and it's coffee-stained but functional. Unprofessionally sticky, but functional.
