Review: The Handy Little Phone That Gets Out of Your Way - So, I like to support things I love, and things that are different. I have to say, I've really fallen for this little phone. It's called the Atom, as in the smallest unit of matter. And it's made by a strange-phone-producing company called Unihertz. I just want to endorse this phone because it's so dang cool, feels great, and it just plain gets out of my way. For people who don't want to stare at screens when they leave the office, people who would rather spend time with family instead of social networks, and for people who don't want to carry around an enormous wafer of glass in their pocket, this little thing fits the bill. Great for phone calls, calendar, the occasional note or photo. You can even search things on the web, if you really want to. It's just as fast as a giant rectangle and can do the same stuff. But with a screen just over 2", not wanting to spend a beautiful, sunny day on your phone is kind of the point here. As it should be. For my phone wish list, while the Atom doesn't quite check all of the boxes I would like, it does check a lot of them. I didn't realize a phone's form factor would be so important, but that's become my favorite thing about this phone. It's hilariously fun to make calls on this little thing, and it feels GREAT in the hand. So HOW could the Atom be improved? Here are a few things... On Cloud Avoidance For those weird ones among us who want to avoid cloud services, the Atom needs much better USB sync with the Mac. Once you get the hang of USB settings on the phone, third party SyncMate sort of works, but it's slow and cumbersome and sometimes only works if the phone is kept active through the sync. And if you have an old calendar, a lot of contacts, and a few photos, SyncMate will time out every time. You have to rely on manually exporting photos using Android File Transfer. Seriously? This is all a royal pain in 2022 that ought not exist. On Ditching Google Like most Android phones, Google has its tentacles wrapped around the Atom phone. Want to download an app? You have to sign into Google, or find some alternative. Directions? Google. Not to mention Google tracks everything. I realize that escaping Google for syncing, directions, etc. is quite the feat unless you're a Librem 5, a PinePhone or a ClearPHONE. But I wish more companies would try to do it. Seems like Unihertz, with their Apple-like "think different" approach is in a good place to put the "hertz" on Google. I wish they would. On Beefing Up the Battery The battery on the Atom is decent. It will last about a day. Maybe a day and a half with low use. And it might be better still than the tiny Palm Phone. But it could be better. If it would last 3-4 days like my old BlackBerry Classic, you'd really have something. On Right to Repair Lastly, right to repair. Unihertz, please take a cue from companies like FairPhone. Make your phones user upgradable and repairable! List parts and prices on your website and provide instructions to users. At least make the battery easily replaceable. Sustainability is fine, but it's mostly about convenience and long product life for me. On Carrier and Purchase Availability As of this writing, AT&T has booted me, a customer for over a decade, off of their network citing that they would no longer support the Atom. Unihertz says that Verizon will support this phone so long as the SIM card is activated in another phone and the IMEI numbers on the phone are updated (instructions for which are available through Unihertz customer care). Verizon will neither confirm nor deny this, though I have briefly used their prepaid plan with the Atom following this method and the Atom's convenient dual-SIM feature. Enter T-Mobile. To my surprise and glee, T-Mobile openly still supports the Atom, per their customer care AND as reflected through their website's "bring your own phone" IMEI search. So far, the phone works great on T-Mobile, and I'm happy with the service. In short, there needs to be more support for the Atom in the U.S. And there should be more places to buy it and other unique phones like this. You can forget finding the Atom locally, and that's a crying shame. Personally, I blame Americans, with our tendency to buy whatever top corporations sell in the phone stores. We need to work on that. In Summary... I wouldn't say these were cons to me purchasing the phone, so much as they are a "wish list" of things I might like to see next in future iterations of the phone, and upgrades to be made. For me, though the Unihertz Atom doesn't have a perfect score for my wishlist, I would say its most endearing feature, being size, outshines every other phone I've looked at. And that's why I got it. This tiny thing is still such a novelty to me that I can't seem to get over. In terms of form factor and general function, I think Unihertz hit this one out of the park. Looking forward to seeing what comes next for the Atom.
Review: Almost perfect - I've been looking for a smartphone that isn't massive like all the mainstream behemoths. This is the best one I can find so far. To be honest, it's not my ideal phone, but it's close. I have the Jelly pro, and would stick with that, but the battery life on that phone is abysmal. It's great to be able to swap it easily, but if I'm swapping because it doesn't last more than a few hours, that's no good. The Atom has more than double the capacity, and that's enough. I'd still like to be able to swap the battery out easily, but I understand that the Atom is designed as a rugged/waterproof phone, so it makes sense that you can't. Battery life is good, it lasted all day for me YMMV. Compared to the Jelly pro, this phone is pretty thick and heavy. I assume a fair amount of that space and weight is due to the larger battery. It would be amazing if the screen took up nearly all the face of the device like mainstream trends, but that's a compromise I'm willing to live with. I love how small it is, but I'd actually prefer a slightly larger screen. The precision of the touch interface is incredible for a screen this size. I have large fingers, and I rarely select something I'm not aiming for. The only problem I've found with the screen size and touch precision is when using a swype style keyboard, it just doesn't have enough room to read the swipes accurately. If I type out letters individually it has no problems with accuracy. Considering the fact that half a dozen keys fall under my finger when I type, I'm blown away with it's ability to know what I'm going for. Since it's so small I turned on the "play all audio as mono", and it works just fine. I didn't see the point of stereo audio when the speakers are only inches apart. It is loud enough that I can use it as an alarm. Bluetooth has connected perfectly anytime I've used it thus far. I've had no random disconnects or any other issues whatsoever. My Project Fi sim card worked without any trouble, but it reads it as T-Mobile only. Wish it had an SD card slot, but with 64gb of internal storage, this isn't a big deal. The camera is usable quality, but I've only taken two pictures so far, so I can't really judge. One photo was the standard 16mp 4:3 without HDR, the other was 8mp 4:3 with HDR. The HDR was clearer/better. I don't take a lot of pictures anyway, so I'm not the greatest to rate quality. The fingerprint reader doesn't pick up my finger every time, but does at least 50% of the time. I think it's more because you can only have it recognize a small part of your print due to it's small size. To help with this, I put in my thumb print as separate prints, just from different angles. The processor and RAM are certainly enough. I haven't had it freeze or lag on me yet. I don't game, and wouldn't suggest gaming on such a small device, but it works well for video, browsing reddit etc. Altogether, a great phone, and I hope Unihertz keeps up the good work. I'll definitely be looking for their latest model the next time I am looking to upgrade. No phone is perfect, but this one comes pretty close.

## Questions & Answers

**Q: Can I use this phone with my Verizon account?**
A: Yes you can, but you may have to go into the phone and enable the cellular data option. Mine was disabled right out of the box, I took it in to a Verizon store and the guy made it work. Verizon does not list it as a supported phone, but if you already have an active Verizon sim, it should work.

**Q: Can you display the small screen on a large screen like a tv using usb c to a hdmi adapter cable?**
A: No but if you get a chrome cast or a smart tv you can cast YouTube and other media services

**Q: So this phone allows for 2 sim cards from different carriers? How does it know which one to use?**
A: You can select which SIM card to use by default for Cellular Data, Voice, and Text.  For the Cellular Data one, you set it and don't really change it unless you wanted to.  For Voice, I have mine set to prompt me every time I make a call.  I tried that with Text, but with the Google Messages app, it would throw an error stating no default SIM selected.  I selected one as the default and from there, any time I create a new message OR reply to an existing thread, there's a button to allow you to switch between the two different SIM cards.

It defaults to SIM1 & SIM2, but I renamed them to "AT&T" and "T-Mobile", and even color coded them to Blue & Pink, respectively.  During normal operation, the phone is connected to both networks to send & receive calls or texts at any given time, but you'll notice only one will show the "4G" logo to indicate mobile data for that SIM card in the status bar.  The other will show signal strength, but with an "X", indicating it's not connected to cellular/mobile data.

When the phone rings, the call screen is color coded to match the SIM cards since I customized them, so it's easy to determine which SIM card is receiving the call.  When making a call, it prompts me which one to use, along with the names & color codes.

When receiving text messages, it will say "via AT&T" or "via T-Mobile" below the text itself in the Message app to indicate the SIM card receiving the text.  The Messages app will even say "Text message from " and then the SIM card you've selected to text from, and also displays a color-coded SIM card icon with the SIM card number inside the icon (1 or 2).  Tapping that icon brings up the menu to choose which SIM card to send from, which, again, is color coded & has the labels I chose.

I haven't yet found an easy way to toggle the cellular/mobile data between the SIM cards, aside from just going to settings and telling it to switch.

Overall, I'm really happy with how well it handles the different SIM cards, and switching between the two for Voice & Texts is very intuitive.

**Q: Will this phone do voice to text?**
A: Yes.  With the google gboard, there's a mic button you can tap to activate voice to text. You can also use the Google Assistant app for texting, or Android Auto for hands-free driving.

### ⭐⭐⭐⭐⭐ Review
*by R***T on May 10, 2022*

Het wordt hoog tijd om een recensie te schrijven. Ik twijfelde eerst of ik wel uit de voeten zou kunnen met dit apparaat, maar inmiddels ben ik er erg blij mee. Vooral nadat 1 van mijn kinderen me had geattendeerd op de knop om vensters (apps) te kunnen verkleinen (ja, hilarisch). Het 'toetsenbord' is wat klein, natuurlijk, maar door goed op de woord-suggesties te letten hoef je nog maar weinig zelf te typen. Heerlijk dat dit ding gewoon altijd in de broekzak past. Ik ben geen veel-gebruiker van een Smart-phone, maar voor mij is het allemaal meer dan genoeg. De batterij gaat ruim 1 dag mee, soms wel 2 dagen .. als je er weinig mee doet. Voor het werk gebruik ik een Apple (van mijn werkgever ontvangen), die gebruik ik nog wel eens als ik onderweg wel graag een groot scherm wil; maar voor 'grote' zaken heb ik het liefst een computer met stevig toetsenbord. PS: de vinger-scan doet het niet zo goed, maar dat geldt ook voor de Apple. Kortom: heerlijk apparaat, die Unihertz Atom.
