That's true. I normally remote start, so by the time I get there, everything should be booted. The Joying I have boots pretty quickly, and connects to the house WiFi pretty fast. I guess it depends how fast the MIFI device boots up and creates a connection for it to catch.
[FYT Android Head Units] mastrv:
Why do I reboot instead of sleep? It's like when you call for support...the first thing they ask is to reboot to see if the issue has gone away. In any case, it starts up fast enough. The connection is pretty quick, as well. I do a few things when it starts up...I turn off the screen lock, connect to VPN, start Waze and PowerAmp. The WiFi on the head unit connects pretty quickly to the hotspot.

With Samsung phones, they come with Bixby. It's like Macrodroid or Automate or Tasker. You set the rules and actions. I have mine set to perform an action when the head unit bluetooth is connected. My phone automatically connects to the head unit bluetooth. The Bixby routine then turns on the hotspot, WiFi on the phone is turned off and Mobile data is turned on. When I shut off the car, the routine turns off hotspot, turns on WiFi and then turns off mobile data. That suits me for now. There are other conditions that can be set like location, specific SSIDs connected to, etc.

This is a cost thing, as well. If you have a MiFi in the car, that means you need another SIM with corresponding data plan. There's the cost of the MiFi and then you have to figure out how to work with the MiFi...do you leave it on all the time so that it connects as soon as you get in the car? That's OK if your going on short errands. Overnight, does the charge last long enough? What if you leave the car over the weekend...keep it on the whole time?

Anyway, each person does what's more convenient or what they prefer. I tried the MiFi and it was less convenient and more costly than what I have now. Also, where I am, the data plans are more expensive than in other parts of the world, I believe.

So I recorded the screen that shows my inability to change APN settings. Upon further digging, there seems to be a default APN for CMNET that I also cannot change.

Here is the video:

iCloud Drive - Apple iCloud

Store, organize and collaborate on files and folders with iCloud Drive. Easily upload, delete or recover files. Changes will sync across your devices with iCloud.

Any thoughts on how to make my default owner account have access to APN settings? I also tried creating another user account, and that account couldn’t access any settings at all.
[FYT Android Head Units] DroidX2:
I see. Thanks! I have Samsung. Never got around to setting up Bixby, but I may try it. I'll have to eat the initial start up costs, but if it works good enough, that'll be a win. Thanks for your help! Since I have the card, I'll still test and report back regarding the SIM card, as well as steps taken.

So I bought this version with band 4 support in mind ... Let me tell you it has been a big disappointment with Joying. It is the snapdragon 625 I've tried TMobile, att, and Verizon none of which work. Att and T-Mobile get signal and operate but sim connection shuts off randomly. I've replaced sim tray sim card reader and even sim card no luck with keeping connection. It completely drops connection randomly. I went as far as buying a replacement unit since Joying wasn't interested in warranty replacing unit over 4g connection. Both units do the same connect to TMobile 4g momentarily then disconnect, show no sim then reconnect to 3g for 5-10min then back to 4g then disconnects again then repeats. Anyone with snapdragon 625 have luck with TMobile?
[FYT Android Head Units] DroidX2:
Sorry to hear. I considered the Snapdragon due to it's popularity in the US and better compatibility with US bands, but after reading up on both processors, many suggested the UIS chip was a more powerful chip than the SnapDragon verison used.

To report back on my findings - Testing a Verizon Sim Card in a Joying Head Unit

SKU: JY-UQS11N8G-H

CPU: UIS7862 12nm Dual ARM Cortex-A75 + Six ARM A55

Verdict: The Card works, but proper setup must take place.

Kudos to those in this thread that have reported your experiences, which in turn helped me complete this task.

--I currently have a Verizon account with a few lines on it. I added a Tablet/Data line, in which Verizon sent me a Sim Card. I tested my phone SIM CARD in the Unit for signal prior to adding the line, Signal was shown, but no connection to the network

***Note: The IMEI for the Joying Unit shows the device as incompatible to Verizon, so to qualify for the New Line, I needed to use a device with a working IMEI - in which case I used my iPad 5, copying the IMEI of that device to the Verizon website to complete the transaction.

--Once SIM Card arrived, I placed it in the iPad for activation. After activation, SIM Card was then placed in Joying Unit. I then restarted the Unit. After restart, Unit was showing 4G Signal, but internet was not working. There didn't seem to be a clear way to add a new APN, so I turned on my phone hotspot to download the ADDAPN app. Upon opening the app, I was given the option to add a new APN.

APN Settings:

I had to do a little digging and modification since even the APN settings from my phone were not a match. My phone is a Samsung Galaxy Note 20 Ultra 5G. Here is what works based on my experience.

NOTE: Unlisted settings were not changed and should be left as "Not Set"

Name: Verizon Internet

APN: VZWINTERNET

MCC: 311

MNC: 480

APN Type: default,supl,mms

APN Protocol: IPv4/IPv6

APN roaming protocol: IPv4

APN enable/disable: APN enabled

Bearer: Unspecified

MVNO: GID

MVNO value: BAE0000000000000

Once complete, I clicked the 3 dots on the top right corner, and Saved the settings. Afterward, I restarted the Unit. Once Unit restarted, Internet was tested and working.

Due to the Unit not having full band compatibility, results may vary based on the Verizon setup in your area, however, mine so far has been good, with an occasional hiccup spot in the usual places where even my phone has issues.

Hopefully, I was able to assist those looking to add a Verizon SIM Card to their Joying Unit. This method may also work with other SIM Cards, such as AT&T or T-Mobile, with the exception that the APN settings may need to be modified.

***This was tested on the below Unit:

[FYT Android Head Units] DroidX2:
Hi Rudy;

The SIM Tray seems to be a bit finicky when installing, so make sure that the SIM is in the correct orientation, and that the metal bracket snaps into place after you place it on the SIM Card and slide it up. You can slightly see the slant in the tray to assist with installation.

It requires a MICRO-SIM, so make sure you have an adapter if your SIM is a NANO SIM. Also, if your SIM install was tight and locked, you could try another SIM Card and see if the connection stays steady.

Although rare, the SIM Tray may have a bad connection on the pins. Try cleaning the SIM Card pins with a cotton swab and alcohol. Restart the Unit after you install the SIM. From there, you may need to manually add your APN settings before you get an actual useable connection.
[FYT Android Head Units] rudy626:
Hello DroidX2, I appreciate the feedback and also your contribution with the Verizon sim write up which I might try tomorrow. I did extensive testing and fiddling with the sim tray on my first unit, went as far as desolderin and resoldering new sim tray with no luck. I also bought a separate sim tray which helped a little but still my issue persists. On this my second unit I am encountering the same issues as my first unit when I first installed it, 4g connection for a couple minutes then disconnects from the network completely.. I will try wedging a piece of paper to help pressure the sim card in place as i haven't done that on this unit and I am using a micro sim card adapter. I am really stuck I installed this unit November of 2021 and to this day cannot get it to work for more than 20 minutes. I am at the point of just trying to wedge the sim or wait for the mint mobile sim if that doesn't do it I will be waiting for the next generation of headunits with hopefully better us modems and sim trays. Also starting to believe maybe T-Mobile is locking out the unit due to IMEI but can not confirm.
[FYT Android Head Units] Litwick87:
Glad I found this thread. I’m thinking about buying a joying 11.6 unit (not sure which chipset I need yet). I have a T-Mobile tablet data plan on an iPad that I never use. I’m hoping to swap it over into the head unit when I do purchase it.
[FYT Android Head Units] DroidX2:
That's odd that the same issue persists with a second Unit. I'm sure the SIM Card works fine in other devices. The metal bracket, at least on my Unit, holds the SIM Card tightly in place once snapped in. If the bracket works correctly, you shouldn't be able to place anything between it and the SIM Card, unless you mean to place it above the bracket inside the SIM holder.

Since you have SnapDragon and T-Mobile, you should have a better connection due to the support for Band 4. On your T-Mobile account, do you have the Unit IMEI registered, or another compatible device IMEI?

I encountered an issue with another Chinese device, one of the Snail Gaming phones, in which I used that device IMEI, and it worked for a while on AT&T, but then suddenly, it just stopped working. I think it may be an Carrier IMEI block. Probably try registering with a common device IMEI first, like an iPad or Android Tablet, and then install into the unit.
[FYT Android Head Units] DroidX2:
Yes, that should work. The Snapdragon does seem to support more US bands, well, one extra, but more support is better, so just swapping the SIM Card should work. Between the two chipsets, Snapdragon is more well known, but tests say the UIS chip is a more powerful chip. However, if you're not a chipset aficionado, you probably won't tell the difference.
[FYT Android Head Units] Litwick87:
For the Jeep specific one I see a single DIN 6/128 and as a pff the shelf I see the Qualcomm 4GB, but I don’t know what the jeep specific one really entails. I’ll need to email them.
[FYT Android Head Units] Litwick87:
Looks like this one plus a Jeep canbus decoder should work for me.

Joying Newest Ultra-Thin Android 11.6" Double Din Car Music Player With Qualcomm Snapdragon System

[FYT Android Head Units] DroidX2:
It seems the vehicle specific models come with prewired harnesses with Canbus if needed, as well as a Dash Trim kit for a more factory install. The Unit itself is the same. The Snapdragon Units seem to max at 4GB RAM, 64GB Storage. The UIS Units go to 6GB/8GB RAM, and 128GB Storage.
[FYT Android Head Units] Litwick87:
Ahh so no need for a separate canbus decoder
[FYT Android Head Units] DroidX2:
Most likely you will need one if your Factory Unit had Car related features. Jeep may have UConnect like Dodge, and if so, then you'll need the CANBUS for steering wheel controls as well as other features. But the Canbus should come in the box with the Jeep Unit. But if you get the universal Unit, you will need to get the Canbus and Trim kit separately. Also, measure your dash, because the 11.6 doesn't sit flush in my vehicle. It fits fine, but one side isn't snapped in place due to the dash design. I would probably need the 10.1 inch screen for a fully flush install.
[FYT Android Head Units] Litwick87:
My car (2012 wrangler) is listed as compatible for the 11.6, but you’re right I’ll measure before ordering.
[FYT Android Head Units] rudy626:
That is a great suggestion I will attempt this tomorrow as I will be off and have some time to go over it. Another development that I kind of feel embarrassed to admit was that today I locked the radio to wcdma only and it works and maintains connection on 3g. I can't believe I didn't think of this sooner, but yeah I tested this with 4hrs of driving today and 0 issues besides top speeds of 5mbps. Still as soon as I switch to 4g it will lose connection. Now I am starting to think it's a comparability issue with frequency range.
[FYT Android Head Units] DroidX2:
Locked to WCDMA? You should be able to change it back in the Android Settings to Global. Sometimes the true Settings for these Units are hidden and you'll need an app like Activity Launcher to access them. With your Unit being the SnapDragon, once you set it to 4G, you should get a decent connection. If not, then definitely check your APN settings. I think it's the BEARER section, make sure the LTE options are selected. The ones I posted are for Verizon, so T-Mobile may be slightly different.
[FYT Android Head Units] Litwick87:
I guess I probably shouldn’t get the snapdragon unit. This is from joying.

“Sorry our snapdragon 11.6 unit cannot compatible with our jeep canbus harness, if you want to purchase our snapdragon 11.6 unit, you need to purchase the suitable canbus harness from other place.

If you choose our 7862 system 11.6" head unit, then it can work with our Jeep canbus harness which is plug and play for your car.”

Best regards

[FYT Android Head Units] dorfious:
If anyone has successfully swapped IMEI numbers on one of these crazy units, will you PM me details? I paid for both T-Mobile and Verizon sims with no success. So far, $60 in the hole.
[FYT Android Head Units] DroidX2:
For Verizon, I didn't do a IMEI swap per se, but instead, I used a compatible device such as an iPad 5 to activate the line. Once the card was activated, I removed it from the iPad and placed it in the Joying Unit, updated the APN settings, and restarted the JOYING and it worked.
[FYT Android Head Units] DroidX2:
Maybe due to the snapdragon chip differences, the canbus they have doesn't communicate correctly. Weird indeed. The Unit itself should work, but you will lose car related features through the Unit due to not having a canbus.
[FYT Android Head Units] Litwick87:
I’ll take my chances without having extended band LTE on T-Mo over not having CANBUS/steering wheel controls.

All else fails what’s a decent car router I can stick a SIM card in? Something I can maybe tuck away?
[FYT Android Head Units] DroidX2:
Even though my connection works, due to the limited bands supported, I have been researching some MiFi devices. There's an extra USB Connection on the back of the Joying Unit that I was thinking of simply adding the MiFi device to it. However, to avoid the extra charge for a data line, as another user (MASTRV) suggested, depending on your device, you can set it up to use Hotspot when it automatically Bluetooth connects to the Unit.

These are the pros/cons for each setup I have gathered.

SIM Card in Unit;

PROS: Instant connection; no extra peripheral needed, full speed under good connection

CONS: possible disconnects due to limited band support, finding correct APN settings, expensive charge with opening new line on account

HOTSPOT:

PROS: creates solid, stable WiFi connection, simple setup

CONS: mostly manual setup, requires manual turn on with every vehicle start-up if not automated, hotspot speed limited by carrier, phone required

MIFI DEVICE:

PROS: creates stable WiFi connection for unit and other devices in car, gives full speed connection not limited like certain hotspot connections, can be tucked away for clean installation, has battery for constant power and instant on when vehicle starts up.

CONS: extra peripheral cost, expensive start up cost if opening new line on account, needs to be powered for faster connection from vehicle start-up or slower connection time due to device power up if battery depletes.

I have not used a MiFi device, so there may be some other pros and cons, but from what I have gathered, those are most of the situations you should run into with each setup.

As for In-Car WiFi devices, HOTSPOT or MIFI are good choices. The better MIFI device depends on your chosen company. For Verizon, I am considering either the MIFI 7100L or 8100L. The 5G models are more expensive, and based on reviews, may need some polishing before I am willing to spend more for a device being used in the vehicle for short driving periods.
[FYT Android Head Units] Litwick87:
Welp I ordered

ill keep all this In mind after testing. I just ordered the UIS version + all 4 accessories. Here goes nothing..
[FYT Android Head Units] DroidX2:
Nice! Congrats! It's a nice really nice Unit. I'm satisfied with my purchase. I even have a Firestick attached to it just in case a streaming app doesn't work. That's one of the reasons I am thinking about getting the MiFi, since I won't have to switch to Hotspot when using the FireStick. Also, if I want to play Gamepass, I may need a faster, more stable connection.

Hopefully you are able to get everything set up correctly. There is a wire in the back that has to be connected for the canbus to work. Mine came connected from factory, but my vehicle doesn't need canbus. You will also need to select and activate your canbus in the Unit. From there, you should be able to program the Steering Wheel controls.

Shipping will take about 2 weeks. I ordered on the 9th and it arrived on the 20th.
[FYT Android Head Units] mastrv:
A MiFi is a device that creates a "hotspot" the same way a phone would/does. The FireStick should be able to connect to a phone's hotspot just as it would connect to a MiFi's hotspot.

You can always try out with your phone's hotspot and then if it doesn't work, then get or try out the MiFi.
[FYT Android Head Units] Litwick87:
With a mifi I can just pop a T-Mobile SIM card in and hopefully run? Or do I need a new plan.

I’m really hoping I can use my iPad data plan as that thing is gathering dust. I use SoundCloud a lot and don’t want to stream things off my phone if I have a perfectly good android head unit.
[FYT Android Head Units] mastrv:
I think it depends on several things:

First, does T-Mobile allow this.

Second, does the plan allow it.

Three, the MiFi itself

These were some of the things when I had/used a MiFi several years ago. Best way is to just try it. For the MiFi, you may need specific a MiFi that works with your provider, T-Mobile. Go in to a T-Mobile store, if possible, and try on a MiFi in the store. Not all MiFis are equal. Best way is to try out the MiFi in the areas or routes you normal use.

If you have a MiFi or are going to get one other than directly from T-Mobile, you might need to unlock it. You'll need to check that as well. Some places have laws that require providers provide unlock info/methods. You may also be able to get unlock info from various sites...not sure about it.

I switched providers and my old MiFi did not work at it's best in certain locations as it did not have all bands of the new provider I was switching to.

There are some pretty nifty MiFis available. I had the 763s wireless aircard MiFi: https://www.ltemifi.com/sierra-763s-wireless-aircard-4g-lte-mobile-hotspot-647.html This was before they had 5G and colour LCD displays.

Just some things/info to consider.
[FYT Android Head Units] Litwick87:
Mine says it will be here on Wednesday.
[FYT Android Head Units] DroidX2:
Nice! Maybe yours is coming from the US warehouse. If it's coming from the China warehouse that's pretty amazing!

I have a Dasaita right now but thinking about new unit with built in cellular to combine with it. Using phone as hotspot is hit or miss, even in the same locations from day to day. Some days I get 40mbps down, some I get .1 until I toggle wifi on/off a few times.

If I'm going to invest again and eat the loss selling the Dasaita, I would prefer one with a 5g modem but I'm guessing those don't exist yet? Searching just gives me references to 5ghz wifi
[FYT Android Head Units] DroidX2:
I can confirm the Firestick works excellently with Hotspot, so it should have no issue with a MiFi device.
[FYT Android Head Units] DroidX2:
Yeah, to be honest, we're lucky to have these Units running full Android, especially here in the US. I doubt there is a 5G head unit as these units still don't support full 4G bands for all carriers here. I do believe that EU and ASIA are larger markets and also where the companies are located, so the devices are made to work in those areas primarily. I have the Joying Unit, so I can only confirm that the T-Mobile plan you mention should work on the Unit, albeit missing a band or 2.

Whichever Unit you choose, check its cellular band compatibility and confirm that it supports bands for your selected carrier. From my experience, I am using Verizon on the Joying Unit, and it has compatibility with 2 of Verizon's 4G bands. The connection is pretty stable for the most part, but sometimes I do get an occasional slow moment before things pick back up. The connection also is not the fastest. This was noticed when I tried to lock a YouTube video to 1080p. Setting back to Auto allowed it to adjust an maintain playback, albeit with some quality drops in the video.
[FYT Android Head Units] magconp:
I just got the universal 7inch model for my Subaru Outback.

i was hoping to just pop in the sim from a tmobile phone that I have as a backup device that never really leaves the house.

but the phone uses a nano sim and I can't tell what the joying takes. It looks like something about 1in square with 8 contacts.

i got the unit off Amazon, so maybe its an older style?

What format sim cards are people using?
[FYT Android Head Units] magconp:
ok. Found an adapter and now have 5 bars and streaming some tunes!

for others referenc3, these take a micro sim ans o ly use 6 of the 8 connectors in the dongle.
[FYT Android Head Units] Litwick87:
I installed the unit and popped in the T-Mobile sim.

No bars.

Tried the AddAPN app, but that didn’t work either. I’ll have to mess with it
[FYT Android Head Units] Litwick87:
hmm my tmobile sim from my ipad didnt work by simply putting it in with an adapter.
[FYT Android Head Units] magconp:
Mine was from anither android phone. Maybe theres a difference?
[FYT Android Head Units] DroidX2:
After installing the SIM Card, did you restart the Unit?
[FYT Android Head Units] Litwick87:
A few times, yeah.
[FYT Android Head Units] DroidX2:
Hmm, in that case, check to see if the data is turned on. Perhaps from messing with it, you may have turned it off accidentally. Also, make sure WiFi is turned off, or it's not in airplane mode or something. Hope that helps.
[FYT Android Head Units] Litwick87:
Yeah I don’t know what changed on it’s own but it was working when I checked this morning!

I need to go on a flight/trip so I’ll be taking the SIM card back out and into my iPad. Here’s to hoping this trading back and forth works.
