The essential little kit

The nec Nothing to say it's perfect I already have the little Atom and the Titan this one is me ideal compromise.

5.0 out of 5 stars I love this phone

I've only had the Unihertz Atom L for a few days, but so far I'm LOVING it.

I love how small it is. I'm so sick of giant 6"+ slab phones that everyone makes these days. I wouldn't go any smaller than a 4 inch screen though. It doesn't give me any trouble that any other larger touchscreen wouldn't also give me, but any smaller, and I imagine it would.

This phone lasted over 60 hours before needing charged.

It's not the latest, greatest, fastest phone on the market by a long shot, but it is the smallest one with the best specs that won't cost as much as a used car, and for that, I'm grateful.

I can't possibly recommend this thing enough(unless you have large hands, then you'll probably hate how small it is). I hope this thing continues to work as it has, and I hope the company sticks around making small budget phones like this one for a LONG time.

I haven't tried playing any games on it, and I haven't had any issues requiring customer service, so I can't really comment on those things, but I have seen review videos with people playing games with this and the Jelly 2, which has essentially the same hardware, so it can definitely be done.

Update: it's now May 2022, and the only "issue" I have to report is for whatever reason it won't do the wireless update it keeps reminding me about once a week, but everything works perfectly. I really hope this company keeps making small rugged phones like this one because it's my favorite phone I've ever owned.

A good and practical phone that is rugged -Be careful on compatibility with cell twr updates

This UPDATES MY REVIEW. MARCH 2022, I used mine with Consumer Cellular. With a drop of 3G my phone worked on Data, but not did not process calling. CC and local reps at Target could not fix what they said to be a SIM card incompatibility. And that forced me to buy a sleazy new phone. I like my Atom L much better. Be wary of this problem and if anyone has better advice please provide info.

---------- Orig review -----------My first smart phone was a petite Atom which I liked. This continued to work following ocean immersion. As I became a heavier user I needed a larger phone with higher capacity battery. The Atom L met that requirement. Although a larger size it is still not too big and the larger screen, especially keyboard, is nice. It seems very rugged and has other added capabilities (over the Atom) such as SD card compatibility. The camera is very good. I use Consumer Cellular and some system settings had to be changed to download data with easy tech support of CU, I found a nice rotating clip case by Turtleback (for iPhone 5/5S/SE) that is a perfect fit (itemA-PMPVerSMExtHDL2). Other on-line reviews cover the phone in more detail. Overall a good practical phone that is not fragile. The owner manual is a bit too minimal. That should be improved.

An update a year later - still working fine with good battery life. Yesterday after dark dropped it off the end of a pier in sea water. Using a crab net I recovered it this AM and after a period it seemed to recover fine and tests our OK and seems to be fully functional again. I would buy this again. I think a good choice for heavy duty use where a basic, non-glitz, smart phone is the requirement.

small screen phone

it might be difficult to read the lcd for some people, I'm fine with the pixel size. I don't know how long this battery is gonna last, you can't replace the battery. I'm currently with mint mobile as the carrier. this camera has a 48 megapixel 8000x6000 jpg output. sometimes I can see screen burns, if I leave the color screen saver on it usually massage's it away.

It perfectly satisfy my demand!

Not the perfect phone but with every new phone being the size of a large stone tablet, this phone is a blessing. Camera is a little bad but I don’t use my phone camera often so meh. The back and open apps buttons at the bottom are light sensors not touch sensors so they don’t or barely function in the dark. Other than that the performance is awesome and the battery life is great. First smartphone I’ve owned that is actually comfortable in one hand.
