Unihertz Atom XL, The Smallest DMR Walkie-Talkie Rugged Smartphone Android 11 Unlocked 6GB+128GB (Support T-Mobile & Verizon only)

TL;DRThis phone is amazing. In all reality, the only con is the screen brightness in the sun, but I can deal. I've been using it for a month or so now alongside Tasker and Lightning Launcher Extreme and couldn't be happier.-This phone is possibly the best phone I've ever had. The fact that it's unlocked gives it much more prestige.-It is an incredibly snappy phone.-It fits in my pocket and I can use it comfortably with one hand!-The android update (Android 10) gives it great support with apps.-Using it with the AT&T Bring Your Own Phone sim kit with Straight Talk and the service is awesome.-The smaller screen may seem like a bad thing but you can binge Twitch, YouTube, playing games...anything for hours because the phone has less pixels to push AND it has a decent size battery (4300mAh).-Speaker is nice and loud if you need it to be (usually I don't and have it at 50-75% even for alarms and such).-The stock alarms are a great collection of birds chirping, water sounds and noticeable chimes.-The device handles heat very well. Spent 3 hours driving with it mounted to the windshield while it was hot out and had no AC and the device didn't even slow down or drain extra battery while using the GPS.-I've dropped the phone by accident a few times now and the phone hasn't seemed to be affected by it.-The quick charge is another awesome thing with this phone AND it uses USB 3(I know a lot of phones have this, but still a great plus).-I've already gotten used to the red "intelligent button" on the side and have switched around the actions a little to make using it easier for myself.-The NFC chip is very quick as well.-The Intelligent Assistant has a bunch of great things that give the phone greater quality of life changes such as the app blocker, which has 4 options for EVERY app (Boot Locker, Start Blocker, Background Blocker, and Background Cleanup). Definitely look into this part of the assistant if you want to maximize your battery life. (I can use my phone regularly for 3 days without having to charge.)-I don't have any bluetooth or wifi issues.-I haven't used the headphone jack or radio yet.I really can't think of any notable cons. I absolutely love this phone. If this changes in the future, be sure I'll update my review once again.

There is no technical support if you need one. I had problem with messages sometimes and they do not respond.Update: I had problems with messages first and while I was waiting for their responses I got more problems. I could not hear people more and more. So after 20 days I could not use phone at all. Their response was to change IMEI number , but their instructions how to do it did not work on my phone. This "technical support" looks like this. You write them what problem you have, you get answer in 2-3 days asking to send the video of the problem, you send the video, in 2-3 days you get an advice what to do, it is not clear and you ask to give more details , in 2-3 days you get more details, you try but it does not work and you write and explain what exactly does not work, in 2-3 days they ask you to send a video etc. I am still waiting for their next response, but returned the phone while I could.

The only difference between this phone and the Atom L is the addition of a DMR antenna. However, despite this distinguishing feature being an additional $50 cost, there wasn't any information for me exactly what frequencies are able to be programmed into this device. Now that I have the phone, I can tell you that it can receive & transmit on any frequency between 400MHz and 480 MHz. Both Digital and Analog modes are supported.Options for Analog Channels:* Channel name (Label the channel)* Channel ID (up to 48 different channels can be defined per zone)* Send frequency (between 400MHz and 480Mhz, definable to resolution of 1 hz)* Recv frequency (between 400MHz and 480Mhz, definable to resolution of 1 hz)* Band (either Narrow Band or Wide Band)* Power (either "Low Power" or "High Power", doesn't specify wattage)* Squelch Level (between 0 and 10, 2 is default and 1 works fine for me. 0 leaves the receiver on all the time.)* Recv subAudio type (either "Wave", "CTCSS", "CDCSS" or "Reverse CDCSS")* Send subAudio type (either "Wave", "CTCSS", "CDCSS" or "Reverse CDCSS")Options for Digital Channels:* Channel name (Label the channel)* Channel ID (up to 48 different channels can be defined per zone)* Send frequency (between 400MHz and 480Mhz, definable to resolution of 1 hz)* Recv frequency (between 400MHz and 480Mhz, definable to resolution of 1 hz)* Power (either "Low Power" or "High Power", doesn't specify wattage)* Color code (integers between 0 and 15 inclusive, not sure what this changes)* Double slot (either "Direct mode", "Slot 1", or "Slot 2")* Mic gain (either 0, 1, or 2, assumedly dB)* Contact type (either "Person", "Group" or "All")* Contact Number (1-16776415)* Encrypt switch (either "Off" or "On")Obviously you will want to stick to the pre programmed FRS frequencies if you are not licensed to use others. FRS frequencies are preprogrammed for "China", "China Taiwan", "EU", "USA", "Aus", "Rus", "Norway", and "South Africal". GMRS frequencies are also pre-programmed for the USA, but it is illegal in the United States to transmit on any frequency in the 400MHz to 480MHz range other than the FRS frequencies without permission & licensing from the FCC. Stick to "USA FRS" if you are unlicensed.The name of the app used for DMR is "Intercom", it is version 2.0.
